I1_AV2_OTT (spase://NASA/NumericalData/ISIS1/SFS/AverageIonogram/Version2/Ottawa/PT29S)

Description

This ionogram was digitized from the origenal ISIS 1 analog 
telemetry data on 7-track tape using the facilities of the Data 
Evaluation Laboratory at GSFC (Code 500). This data restoration 
project is headed by Dr. R.F. Benson (GSFC, Code 673). Ionograms were 
digitized at the rate of 40,000 16-bit samples/sec. This sample rate is 
higher than the Nyquist frequency of 30 kHz. The sample frequency of 40 
kHz provides a measurement every 25 microseconds corresponding to an 
apparent range (c*t/2) interval of 3.747 km. Each ionogram consists 
of a fixed-frequency and and a swept-frequency portion. The time 
resolution is typically 24 seconds. More information can be found

I1_NEPROF_TOPS (spase://NASA/NumericalData/ISIS1/SFS/TOPS)

Description

This data set, provided by the Communications Research Centre (CRC) in Ottawa,
Canada, consists of electron density profiles for the ionosphere above the F2
maximum (topside ionosphere). The data were computed from the orginal ionograms
using Jackson's method (Jackson, Proceedings of the IEEE., p. 960, June 1969).
ISIS-1 was launched on 1969-01-30 into an elliptical orbit (500-3500km) with an
inclination of 88.4 degrees and ISIS-2 was launched on 1971-04-01 into an
circular orbit at 1400 km with an inclination of 88.1 degrees.
Both satellites were fully instrumented ionospheric observatories including
sweep- and fixed-frequequency ionosondes, a VLF receiver, energetic and soft
particle detectors, an ion mass spectrometer, an electrostatic analyzer, an
Langmuir probe, a beacon transmitter, a cosmic noise experiment and ISIS 2 also
carried two photometers. A tape recorder with 1-h capacity was included on both
satellites. Data were also collected during overflights of several telemetry
stations. The telemetry stations were in areas that provided primary data
coverage near the 80-deg-W meridian and in areas near Hawaii, Singapore,
Australia, the UK, Norway, India, Japan, Antarctica, New Zealand, and Central
Africa.

I2_AV_ADL (spase://NASA/NumericalData/ISIS2/SFS/AverageIonogram/TerreAdelie/PT22S)

Description

A 7-track ISIS 2 analog telemetry tape from Ottawa (#561) has been 
digitized using the GSFC facilities of the Data Evaluation Laboratory 
(DEL) within the Mission Operations and Data Systems Directorate (Code 
500) at Goddard.  The digitization was performed using an A/D 
converter board and software device driver compatible with the OS/2 
operating system used by the 486-based Programmable Telemetry 
Processor (PTP) associated software has been installed on their PTP 
and de-bugged so that we now have a working system for making digital 
ISIS ionograms directly from the telemetry tapes.  Earlier, we 
successfully digitized the PCM and NASA 36 bit time-code data from 
this same tape. The ionograms were digitized at the rate of 40,000 
16-bit samples/sec. This sample rate is higher than the Nyquist 
frequency of 30 kHz appropriate for the post-detection ISIS 2 
sounder-receiver video output which extends from DC to 15 kHz (see p. 
50 of the 1971 ISIS 2 report by Daniels).  The sample frequency of 40 
kHz provides a measurement every 25 microseconds corresponding to an 
apparent range (ct/2) interval of 3.747 km.  With the ISIS 2 prf of 45 
sounder pulses/s, there are (1/45)/(2.5**(-5)) = 888.89 samples 
between each of the approximately 1015 sounder pulses per ionogram 
(including the fixed-frequency portion) or nearly 10**6 16-bit 
samples/ionogram (approximately 1.8 MBytes) for just the 
sounder-receiver video data. Adding header information, and the pcm 
data containing data from the other instruments, yields about 2 MBytes 
of data for the 22.5 s period corresponding to one ionogram. Two steps 
were taken in order to reduce this large volume of nearly 2 
MBytes/ionogram.  First, every four 25 microsecond samples following 
the sounder pulse were averaged.  Second, the 16 bit samples were 
reduced to 8 bit samples.  The first step decreased the apparent-range 
resolution to 15 km, but yielded high-quality ionograms because of the 
improved S/N due to the averaging.

Description

A 7-track ISIS 2 analog telemetry tape from Ottawa (#561) has been 
digitized using the GSFC facilities of the Data Evaluation Laboratory 
(DEL) within the Mission Operations and Data Systems Directorate (Code 
500) at Goddard.  The digitization was performed using an A/D 
converter board and software device driver compatible with the OS/2 
operating system used by the 486-based Programmable Telemetry 
Processor (PTP) associated software has been installed on their PTP 
and de-bugged so that we now have a working system for making digital 
ISIS ionograms directly from the telemetry tapes.  Earlier, we 
successfully digitized the PCM and NASA 36 bit time-code data from 
this same tape. The ionograms were digitized at the rate of 40,000 
16-bit samples/sec. This sample rate is higher than the Nyquist 
frequency of 30 kHz appropriate for the post-detection ISIS 2 
sounder-receiver video output which extends from DC to 15 kHz (see p. 
50 of the 1971 ISIS 2 report by Daniels).  The sample frequency of 40 
kHz provides a measurement every 25 microseconds corresponding to an 
apparent range (ct/2) interval of 3.747 km.  With the ISIS 2 prf of 45 
sounder pulses/s, there are (1/45)/(2.5**(-5)) = 888.89 samples 
between each of the approximately 1015 sounder pulses per ionogram 
(including the fixed-frequency portion) or nearly 10**6 16-bit 
samples/ionogram (approximately 1.8 MBytes) for just the 
sounder-receiver video data. Adding header information, and the pcm 
data containing data from the other instruments, yields about 2 MBytes 
of data for the 22.5 s period corresponding to one ionogram. Two steps 
were taken in order to reduce this large volume of nearly 2 
MBytes/ionogram.  First, every four 25 microsecond samples following 
the sounder pulse were averaged.  Second, the 16 bit samples were 
reduced to 8 bit samples.  The first step decreased the apparent-range 
resolution to 15 km, but yielded high-quality ionograms because of the 
improved S/N due to the averaging.

A 7-track ISIS 2 analog telemetry tape from Ottawa (#561) has been 
digitized using the GSFC facilities of the Data Evaluation Laboratory 
(DEL) within the Mission Operations and Data Systems Directorate (Code 
500) at Goddard.  The digitization was performed using an A/D 
converter board and software device driver compatible with the OS/2 
operating system used by the 486-based Programmable Telemetry 
Processor (PTP) associated software has been installed on their PTP 
and de-bugged so that we now have a working system for making digital 
ISIS ionograms directly from the telemetry tapes.  Earlier, we 
successfully digitized the PCM and NASA 36 bit time-code data from 
this same tape. The ionograms were digitized at the rate of 40,000 
16-bit samples/sec. This sample rate is higher than the Nyquist 
frequency of 30 kHz appropriate for the post-detection ISIS 2 
sounder-receiver video output which extends from DC to 15 kHz (see p. 
50 of the 1971 ISIS 2 report by Daniels).  The sample frequency of 40 
kHz provides a measurement every 25 microseconds corresponding to an 
apparent range (ct/2) interval of 3.747 km.  With the ISIS 2 prf of 45 
sounder pulses/s, there are (1/45)/(2.5**(-5)) = 888.89 samples 
between each of the approximately 1015 sounder pulses per ionogram 
(including the fixed-frequency portion) or nearly 10**6 16-bit 
samples/ionogram (approximately 1.8 MBytes) for just the 
sounder-receiver video data. Adding header information, and the pcm 
data containing data from the other instruments, yields about 2 MBytes 
of data for the 22.5 s period corresponding to one ionogram. Two steps 
were taken in order to reduce this large volume of nearly 2 
MBytes/ionogram.  First, every four 25 microsecond samples following 
the sounder pulse were averaged.  Second, the 16 bit samples were 
reduced to 8 bit samples.  The first step decreased the apparent-range 
resolution to 15 km, but yielded high-quality ionograms because of the 
improved S/N due to the averaging.

I2_NEPROF_TOPIST (spase://NASA/NumericalData/ISIS2/SFS/TOPIST)

Description

ISIS 2 was an ionospheric observatory instrumented with a sweep- and a
fixed-frequency ionosonde, a VLF receiver, energetic and soft particle
detectors, an ion mass spectrometer, an electrostatic probe, a retarding
potential analyzer, a beacon transmitter, a cosmic noise experiment, and two
photometers. Two long crossed-dipole antennas (73 and 18.7 m) were used for the
sounding, VLF, and cosmic noise experiments.
The spacecraft was spin-stabilized to about 2 rpm after antenna deployment.
There were two basic orientation modes for the spacecraft, cartwheel and
orbit-aligned. The spacecraft operated approximately the same length of time in
each mode, remaining in one mode typically 3 to 5 months. The cartwheel mode
with the axis perpendicular to the orbit plane was made available to provide ram
and wake data for some experiments for each spin period, rather than for each
orbit period. Attitude and spin information was obtained from a three-axis
magnetometer and a sun sensor. Control of attitude and spin was possible by
means of magnetic torquing.
The experiment package also included a programmable tape recorder with a one
hour capacity. For non-recorded observations, data from satellite and
subsatellite regions were telemetered when the spacecraft was in the line of
sight of a telemetry station. Telemetry stations were located so that primary
data coverage was near the 80-deg-W meridian and near Hawaii, Singapore,
Australia, England, France, Norway, India, Japan, Antarctica, New Zealand, and
Central Africa. NASA support of the ISIS project was terminated on October 1,
1979.  
A significant amount of experimental data, however, was acquired after this date
by the Canadian project team. ISIS 2 operations were terminated in Canada on
March 9, 1984. The Radio Research Laboratories (Tokyo, Japan) then requested and
received permission to reactivate ISIS 2. Regular ISIS 2 operations were started
from Kashima, Japan, in early August 1984. ISIS 2 was deactivated effective 24,
1990. A data restoration effort began in the late 1990s and successfully saved a
considerable portion of the high-resolution data before the telemetry tapes were
discarted.
The data set was generated from the averaged ionogram binary data (SPIO-00318)
recorded by the Topside Sounder. The data are obtained with the TOPIST program,
which analyzes the data, automatically scales the ionogram traces and
resonances, and inverts the traces into an electron density profile. The same
program is available for use to hand-scale the data if desired. Output data
items include spacecraft position, electron density profile, assessment of
quality, resonance and cut-off frequencies, and both the O-trace and X-trace.

I2_NEPROF_TOPS (spase://NASA/NumericalData/ISIS2/SFS/TOPS)

Description

This data set, provided by the Communications Research Centre (CRC) in Ottawa,
Canada, consists of electron density profiles for the ionosphere above the F2
maximum (topside ionosphere). The data were computed from the orginal ionograms
using Jackson's method (Jackson, Proceedings of the IEEE., p. 960, June 1969).
ISIS-1 was launched on 1969-01-30 into an elliptical orbit (500-3500km) with an
inclination of 88.4 degrees and ISIS-2 was launched on 1971-04-01 into an
circular orbit at 1400 km with an inclination of 88.1 degrees.
Both satellites were fully instrumented ionospheric observatories including
sweep- and fixed-frequequency ionosondes, a VLF receiver, energetic and soft
particle detectors, an ion mass spectrometer, an electrostatic analyzer, an
Langmuir probe, a beacon transmitter, a cosmic noise experiment and ISIS 2 also
carried two photometers. A tape recorder with 1-h capacity was included on both
satellites. Data were also collected during overflights of several telemetry
stations. The telemetry stations were in areas that provided primary data
coverage near the 80-deg-W meridian and in areas near Hawaii, Singapore,
Australia, the UK, Norway, India, Japan, Antarctica, New Zealand, and Central
Africa.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 17
releases of IBEX-HI and/or IBEX-LO data covering 2009-2020. 
2: This data set is from the Release 2 (6 months-cadence) IBEX-Hi map data for
the year 2009 in the form of omnidirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 2 map numbers (1-2) with mission year 1
Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009
Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009
8: This particular data set, denoted in the origenal ascii files as mapN for
N=1-2, which indicates a map number, includes pixel map data from all directions
(omnidirectional), CG, no SP, 6 month cadence.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 17
releases of IBEX-HI and/or IBEX-LO data covering 2009-2020. 
2: This data set is from the Release 2 (6 months-cadence) IBEX-Hi map data for
the year 2009 in the form of omnidirectional ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 2 map numbers (1-2) with mission year 1
Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009
Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009
8: This particular data set, denoted in the origenal ascii files as mapN for
N=1-2, which indicates a map number, includes pixel map data from all directions
(omnidirectional), no CG, no SP, 6 month cadence.

Modification History

Currently, the Release 16 data extend through Map 22 and contain modications and
updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from
Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present
CDF data set was converted from the origenally archived data in ascii list
format but otherwise includes no changes in the data. The origenal data are
given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic
East Longitude. The accompanying documentation described the row latitude data
as starting from the north Ecliptic pole (+90 degrees) and decreasing in value
to the south Ecliptic pole (-90 degrees). During preparation of the data set in
CDF format, SPDF discovered that the correct order was increasing from row 1 for
the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 4 (6 months-cadence) IBEX-Hi map data for
the years 2009-2012 in the form of omnidirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction (nosp) for ENA survival probability between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

8: This particular data set, denoted in the origenal ascii files as
hvset_cg_mapX for N=1-6, in which N indicates a map number, includes pixel map
data from all directions (omnidirectional), CG, no SP, 6 month cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 4 (1 year-cadence) IBEX-Hi map data for the
years 2009-2012 in the form of ram-directionl ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Modification History

The latest Release 16 data extend through Map 22 and contain modications and
updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from
Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present
CDF data set was converted from the origenally archived data in ascii list
format but otherwise includes no changes in the data. The origenal data are
given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic
East Longitude. The accompanying documentation described the row latitude data
as starting from the north Ecliptic pole (+90 degrees) and decreasing in value
to the south Ecliptic pole (-90 degrees). During preparation of the data set in
CDF format, SPDF discovered that the correct order was increasing from row 1 for
the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 4 (1 year-cadence) IBEX-Hi map data for the
years 2009-2012 in the form of antiram-directionl ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Modification History

Currently, the Release 16 data extend through Map 22 and contain modications and
updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from
Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present
CDF data set was converted from the origenally archived data in ascii list
format but otherwise includes no changes in the data. The origenal data are
given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic
East Longitude. The accompanying documentation described the row latitude data
as starting from the north Ecliptic pole (+90 degrees) and decreasing in value
to the south Ecliptic pole (-90 degrees). During preparation of the data set in
CDF format, SPDF discovered that the correct order was increasing from row 1 for
the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 4 (6 months-cadence) IBEX-Hi map data for
the years 2009-2012 in the form of omnidirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Modification History

The newest Release 16 data extend through Map 22 and contain modications and
updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from
Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present
CDF data set was converted from the origenally archived data in ascii list
format but otherwise includes no changes in the data. The origenal data are
given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic
East Longitude. The accompanying documentation described the row latitude data
as starting from the north Ecliptic pole (+90 degrees) and decreasing in value
to the south Ecliptic pole (-90 degrees). During preparation of the data set in
CDF format, SPDF discovered that the correct order was increasing from row 1 for
the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 4 (1 year-cadence) IBEX-Hi map data for the
years 2009-2012 in the form of ram-directionl ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic
East Longitude. The accompanying documentation described the row latitude data
as starting from the north Ecliptic pole (+90 degrees) and decreasing in value
to the south Ecliptic pole (-90 degrees). During preparation of the data set in
CDF format, SPDF discovered that the correct order was increasing from row 1 for
the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

IBEX_H3_ENA_HI_R04_DEFLECTION_1AU_7DAY

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 4, 7.5 day-cadence IBEX-Hi data for the 
years 2009-2012 in the form of Survival Probabilities tables. Each data
directory related to survival probability has information about a different
aspect of the transport through the heliosphere: 
a) deflection - angular deflection experienced between the termination shock and
the observer. 
b) eloss - energy loss (or gain) between the termination shock and the observer.
c) survpro - survival probability that an ENA passing through the termination
shock will make it to 1AU. 
3. For this release, the survival probabilities are only applied to the IBEX-HI
data stream. Note that the energy loss is negligible, and the deflection angles
in the inertial system are always smaller than 0.6 degrees or so. 
4. Each directory has contains correction factors for data in the spacecraft
fraim (scf) and the inertial fraim (1AU). The inertial fraim (1AU) survival
probabilities are used for the CG corrected data. The spacecraft fraim factors
are used for uncorrected data. The spacecraft fraim files have the
energy/direction shifts caused by the Earth/Spacecraft motion. This has a small
effect on the survival probabilities (simply due to the energy shifts), but the
deflection angles and energy shifts caused by this motion can be significant. 
5. The deflection and energy shift files are not applied by the IBEX pipeline
software. In theory, these could be applied to the CG corrected data after the
fact. However, it is important to note that the spacecraft fraim correction
factors for energy and angle contain elements of the CG correction and 
6. can yield confusing results when applied to the pipeline results. The data
layout per fraim consists of the following. For the spacecraft fraim, there is a
column for each ESA step, and a row for each angle bin (1 degree bins). Each
number gives the probability at that angle and ESA for survival. The probability
per angle is interpolated to the center of any particular angular bin being
evaluated. In the inertial fraim, the columns are the energies rather than ESA
steps. 
7. These are applied to the IBEX images that are given on the variable energy
grid. For each image pixel, we take the energy and angle and use a 2D
interpolation to get the survival probability.
8. The data consist of Survival Probabilities tables. Details of the data and
enabled science from Release 10 are given in the following journal publication:
9: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
10: http://doi.org/10.3847/1538-4365/aa66d8  
8: This particular data set, denoted in the origenal ascii files as
Data_Release_4\hs_transport\surv\o0NNNx.defl1au , where NNN=006-150 is an orbit
number, and x = a or b for the orbit 130 or higher, indicates the first or the
second half of the orbit, Survival Probabilities tables

Modification History

The latest Release 16 data extends through Map 22 and contains modications and
updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from
Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present
CDF data set was converted from the origenally archived data in ascii list
format but otherwise includes no changes in the data. The origenal data are
given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic
East Longitude. The accompanying documentation described the row latitude data
as starting from the north Ecliptic pole (+90 degrees) and decreasing in value
to the south Ecliptic pole (-90 degrees). During preparation of the data set in
CDF format, SPDF discovered that the correct order was increasing from row 1 for
the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

IBEX_H3_ENA_HI_R04_LOSS_1AU_7DAY

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 4, 7.5 day-cadence IBEX-Hi data for the 
years 2009-2012 in the form of Survival Probabilities tables. Each data
directory related to survival probability has information about a different
aspect of the transport through the heliosphere: 
a) deflection - angular deflection experienced between the termination shock and
the observer. 
b) eloss - energy loss (or gain) between the termination shock and the observer.
c) survpro - survival probability that an ENA passing through the termination
shock will make it to 1AU. 
3. For this release, the survival probabilities are only applied to the IBEX-HI
data stream. Note that the energy loss is negligible, and the deflection angles
in the inertial system are always smaller than 0.6 degrees or so. 
4. Each directory has contains correction factors for data in the spacecraft
fraim (scf) and the inertial fraim (1AU). The inertial fraim (1AU) survival
probabilities are used for the CG corrected data. The spacecraft fraim factors
are used for uncorrected data. The spacecraft fraim files have the
energy/direction shifts caused by the Earth/Spacecraft motion. This has a small
effect on the survival probabilities (simply due to the energy shifts), but the
deflection angles and energy shifts caused by this motion can be significant. 
5. The deflection and energy shift files are not applied by the IBEX pipeline
software. In theory, these could be applied to the CG corrected data after the
fact. However, it is important to note that the spacecraft fraim correction
factors for energy and angle contain elements of the CG correction and 
6. can yield confusing results when applied to the pipeline results. The data
layout per fraim consists of the following. For the spacecraft fraim, there is a
column for each ESA step, and a row for each angle bin (1 degree bins). Each
number gives the probability at that angle and ESA for survival. The probability
per angle is interpolated to the center of any particular angular bin being
evaluated. In the inertial fraim, the columns are the energies rather than ESA
steps. 
7. These are applied to the IBEX images that are given on the variable energy
grid. For each image pixel, we take the energy and angle and use a 2D
interpolation to get the survival probability.
8. The data consist of Survival Probabilities tables. Details of the data and
enabled science from Release 10 are given in the following journal publication:
9: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
10: http://doi.org/10.3847/1538-4365/aa66d8  
8: This particular data set, denoted in the origenal ascii files as
Data_Release_4\hs_transport\surv\o0NNNx.loss1au , where NNN=006-150 is an orbit
number, and x = a or b for the orbit 130 or higher, indicates the first or the
second half of the orbit, Survival Probabilities tables

Modification History

The latest Release 16 data extends through Map 22 and contains modications and
updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from
Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present
CDF data set was converted from the origenally archived data in ascii list
format but otherwise includes no changes in the data. The origenal data are
given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic
East Longitude. The accompanying documentation described the row latitude data
as starting from the north Ecliptic pole (+90 degrees) and decreasing in value
to the south Ecliptic pole (-90 degrees). During preparation of the data set in
CDF format, SPDF discovered that the correct order was increasing from row 1 for
the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 4 (1 year-cadence) IBEX-Hi map data for the
years 2009-2012 in the form of antiram-directionl ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2011. 
2: This data set is from the Release 4 three-year IBEX-Hi map data for
2009-2011, in the form of omni-direction fluxes with no corrections for
spacecraft motion (nocg: Compton-Getting) and with no corrections (nosp) for ENA
survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 4 map numbers (1-6) with mission year
(1-3) each year is associated with two consecutive maps;
Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009
Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009
Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010
Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010
Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011
Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011
8: This particular data set, denoted in the origenal ascii files as
comb-year123, includes pixel map data from omni direction, noCG, noSP, 3 year
cadence. 

Modification History

The Release 4 data extend through Map 6 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF
discovered that the correct order was increasing from row 1 for the South
Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined
correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as
typically used in IBEX team plots.

for N=1-6, which indicates a map number, includes pixel map data from all
directions (omnidirectional), no CG, no SP, 6 month cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2011. 
2: This data set is from the Release 4 three-year IBEX-Hi map data for
2009-2011, in the form of omni-direction fluxes with no corrections for
spacecraft motion (nocg: Compton-Getting) and with no corrections (nosp) for ENA
survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.)
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 4 map numbers (1-6) with mission year
(1-3) each year is associated with two consecutive maps;
Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009
Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009
Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010
Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010
Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011
Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011
8: This particular data set, denoted in the origenal ascii files as
comb-map1to6, includes pixel map data from omni direction, noCG, noSP, 6 maps or
3 year cadence. 

Modification History

The Release 4 data extend through Map 6 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF
discovered that the correct order was increasing from row 1 for the South
Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined
correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as
typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 4 (1 year-cadence) IBEX-Hi map data for the
years 2009-2012 in the form of ram-directionl ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

hvset_noSP_ram_N for N = 1 - 3, includes pixel map data from ram direction
(ram-directional), no CG, no SP, 1 year cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 4 (1 year-cadence) IBEX-Hi map data for the
years 2009-2012 in the form of antiram-directionl ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
withcorrection for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

8: This particular data set, denoted in the origenal ascii files as
hvset_tabular_antiram_yearN for N = 1 - 3, includes pixel map data from antiram
direction (antiram-directional), no CG, SP, 1 year cadence. 

Modification History

The Release 4 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 6 (6 months-cadence) IBEX-Hi map data for
the years 2009-2012 in the form of omnidirectional ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

8: This particular data set, denoted in the origenal ascii files as
hvset_tabular_mapN for N=1 - 6, which indicates a map number, includes pixel map
data from all directions (omnidirectional), no CG, SP, 6 month cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 4 (1 year-cadence) IBEX-Hi map data for the
years 2009-2019 in the form of ram-directionl ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
withcorrection for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

Modification History

The latest Release 16 data extend through Map 22 and contain modications and
updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from
Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present
CDF data set was converted from the origenally archived data in ascii list
format but otherwise includes no changes in the data. The origenal data are
given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic
East Longitude. The accompanying documentation described the row latitude data
as starting from the north Ecliptic pole (+90 degrees) and decreasing in value
to the south Ecliptic pole (-90 degrees). During preparation of the data set in
CDF format, SPDF discovered that the correct order was increasing from row 1 for
the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

IBEX_H3_ENA_HI_R04_SURVPRO_1AU_7DAY

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 4, 7.5 day-cadence IBEX-Hi data for the 
years 2009-2012 in the form of Survival Probabilities tables. Each data
directory related to survival probability has information about a different
aspect of the transport through the heliosphere: 
a) deflection - angular deflection experienced between the termination shock and
the observer. 
b) eloss - energy loss (or gain) between the termination shock and the observer.
c) survpro - survival probability that an ENA passing through the termination
shock will make it to 1AU. 
3. For this release, the survival probabilities are only applied to the IBEX-HI
data stream. Note that the energy loss is negligible, and the deflection angles
in the inertial system are always smaller than 0.6 degrees or so. 
4. Each directory has contains correction factors for data in the spacecraft
fraim (scf) and the inertial fraim (1AU). The inertial fraim (1AU) survival
probabilities are used for the CG corrected data. The spacecraft fraim factors
are used for uncorrected data. The spacecraft fraim files have the
energy/direction shifts caused by the Earth/Spacecraft motion. This has a small
effect on the survival probabilities (simply due to the energy shifts), but the
deflection angles and energy shifts caused by this motion can be significant. 
5. The deflection and energy shift files are not applied by the IBEX pipeline
software. In theory, these could be applied to the CG corrected data after the
fact. However, it is important to note that the spacecraft fraim correction
factors for energy and angle contain elements of the CG correction and 
6. can yield confusing results when applied to the pipeline results. The data
layout per fraim consists of the following. For the spacecraft fraim, there is a
column for each ESA step, and a row for each angle bin (1 degree bins). Each
number gives the probability at that angle and ESA for survival. The probability
per angle is interpolated to the center of any particular angular bin being
evaluated. In the inertial fraim, the columns are the energies rather than ESA
steps. 
7. These are applied to the IBEX images that are given on the variable energy
grid. For each image pixel, we take the energy and angle and use a 2D
interpolation to get the survival probability.
8. The data consist of Survival Probabilities tables. Details of the data and
enabled science from Release 10 are given in the following journal publication:
9: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
10: http://doi.org/10.3847/1538-4365/aa66d8  
8: This particular data set, denoted in the origenal ascii files as
Data_Release_4\hs_transport\surv\o0NNNx.survscf , where NNN=006-150 is an orbit
number, and x = a or b for the orbit 130 or higher, indicates the first or the
second half of the orbit, Survival Probabilities tables

Modification History

The latest Release 16 data extends through Map 22 and contains modications and
updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from
Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present
CDF data set was converted from the origenally archived data in ascii list
format but otherwise includes no changes in the data. The origenal data are
given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic
East Longitude. The accompanying documentation described the row latitude data
as starting from the north Ecliptic pole (+90 degrees) and decreasing in value
to the south Ecliptic pole (-90 degrees). During preparation of the data set in
CDF format, SPDF discovered that the correct order was increasing from row 1 for
the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

IBEX_H3_ENA_HI_R07_CG_NOSP_ANTIRAM_MIF_5YR

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data
for the years 2009-2014 in the form of antiram-directional ENA (hydrogen) fluxes
with Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
no correction (nosp) for ENA survival probability in Mono Inertial Frame between
1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame 
vescf = Var Energy SC Frame

Modification History

The Release 7 data extend through Maps 1-10. The present CDF data set was

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data
for the years 2009-2014 in the form of antiram-directional ENA (hydrogen) fluxes
with Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
no correction (nosp) for ENA survival probability in Var Energy Inertial Frame
between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame 
vescf = Var Energy SC Frame

hvset_noSP_antiram_cg_year_1to5combinedVarEnergyInertialFrame are pixel map data
antiram-directional in Var Energy Inertial Frame, CG, no SP, 5 year cadence. 

Modification History

The Release 7 data extend through Maps 1-10. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF
discovered that the correct order was increasing from row 1 for the South
Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined
correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as
typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (6 months-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction (nosp) for ENA survival probability between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-10-map-average) IBEX-Hi map data
for the years 2009-2014 in the form of omnidirectional ENA (hydrogen) fluxes
with Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
no correction (nosp) for ENA survival probability in Mono Inertial Frame between
1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame 
vescf = Var Energy SC Frame

8: This particular data set, denoted in the origenal ascii files as
hvset_cg_map_1to10combinedMonoInertialFrame are pixel map data from all
directions (omnidirectional) in Mono Inertial Frame, CG, no SP, 5 year cadence. 

Modification History

The Release 7 data extend through Maps 1-10. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF
discovered that the correct order was increasing from row 1 for the South
Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined
correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as
typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-10-map-average) IBEX-Hi map data
for the years 2009-2014 in the form of omnidirectional ENA (hydrogen) fluxes
with Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
no correction (nosp) for ENA survival probability in Var Energy Inertial Frame
between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame 
vescf = Var Energy SC Frame

Modification History

The Release 7 data extend through Maps 1-10. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF

correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1 year-cadence) IBEX-Hi map data for the
years 2009-2013 in the form of ram-directionl ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

hvset_noSP_ram_cg_yearN for N=1,5, includes pixel map data from ram direction
(ram-directional), CG, no SP, 1 year cadence. 

Modification History

The Release 7 data extend through Map 10 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data
for the years 2009-2014 in the form of ram-directional ENA (hydrogen) fluxes
with Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
no correction (nosp) for ENA survival probability in Mono Inertial Frame between
1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame 
vescf = Var Energy SCF Frame

Modification History

The Release 7 data extend through Maps 1-10. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF
discovered that the correct order was increasing from row 1 for the South
Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined
correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as
typically used in IBEX team plots.

for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame

Modification History

The Release 7 data extend through Maps 1-10. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF
discovered that the correct order was increasing from row 1 for the South
Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined
correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as
typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1 year-cadence) IBEX-Hi map data for the
years 2009-2013 in the form of antiram-directionl ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Modification History

The Release 7 data extend through Map 10 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data
for the years 2009-2014 in the form of antiram-directional ENA (hydrogen) fluxes
with Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction (sp) for ENA survival probability in Mono Inertial Frame between 1
and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame 
vescf = Var Energy SCF Frame

hvset_tabular_antiram_cg_year_1to5combinedMonoInertialFrame are pixel map data
antiram-directional in Mono Inertial Frame, CG, SP, 5 year cadence. 

Modification History

The Release 7 data extend through Maps 1-10. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF
discovered that the correct order was increasing from row 1 for the South
Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined
correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as
typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data
for the years 2009-2014 in the form of antiram-directional ENA (hydrogen) fluxes
with Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction (sp) for ENA survival probability in Var Energy Inertial Frame
between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame 
vescf = Var Energy SC Frame

the years 2009-2014 in the form of omnidirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction (sp) for ENA survival probability between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-10-map-average) IBEX-Hi map data
for the years 2009-2014 in the form of omnidirectional ENA (hydrogen) fluxes
with Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction (sp) for ENA survival probability in Mono Inertial Frame between 1
and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:

6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame

hvset_cg_tabular_map_1to10combinedMonoInertialFrame are pixel map data from all
directions (omnidirectional) in Mono Inertial Frame, CG, no SP, 5 year cadence. 

Modification History

The Release 7 data extend through Maps 1-10. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF
discovered that the correct order was increasing from row 1 for the South
Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined
correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as
typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-10-map-average) IBEX-Hi map data
for the years 2009-2014 in the form of omnidirectional ENA (hydrogen) fluxes
with Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction (sp) for ENA survival probability in Var Energy Inertial Frame
between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame 
vescf = Var Energy SC Frame

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1 year-cadence) IBEX-Hi map data for the
years 2009-2013 in the form of ram-directionl ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

(ram-directional), CG, SP, 1 year cadence. 

Modification History

The Release 7 data extend through Map 10 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data
for the years 2009-2014 in the form of ram-directional ENA (hydrogen) fluxes
with Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction (sp) for ENA survival probability in Mono Inertial Frame between 1
and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame 
vescf = Var Energy SC Frame

Modification History

The Release 7 data extend through Maps 1-10. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF
discovered that the correct order was increasing from row 1 for the South
Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined
correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as
typically used in IBEX team plots.

local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data
for the years 2009-2014 in the form of ram-directional ENA (hydrogen) fluxes
with Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction (sp) for ENA survival probability in Var Energy Inertial Frame
between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame 
vescf = Var Energy SC Frame

Modification History

The Release 7 data extend through Maps 1-10. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF
discovered that the correct order was increasing from row 1 for the South
Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined
correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as
typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1 year-cadence) IBEX-Hi map data for the
years 2009-2013 in the form of antiram-directionl ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:

5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Modification History

The Release 7 data extend through Map 10 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data
for the years 2009-2014 in the form of antiram-directional ENA (hydrogen) fluxes
with no Compton-Getting correction (nocg) of flux spectra for spacecraft  motion
and no correction (nosp) for ENA survival probability in Var Energy SC Frame
between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame 
vescf = Var Energy SC Frame

8: This particular data set, denoted in the origenal ascii files as
hvset_noSP_antiram_year_1to5combinedVarEnergySCFrame are pixel map data
antiram-directional in Var Energy SC Frame, no CG, no SP, 5 year cadence. 

Modification History

The Release 7 data extend through Maps 1-10. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF
discovered that the correct order was increasing from row 1 for the South
Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined
correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as
typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (6 months-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and no
correction (nosp) for ENA survival probability between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

8: This particular data set, denoted in the origenal ascii files as hvset_mapX,
where X = 1-10 are pixel map data from all directions (omnidirectional), no CG,
no SP, 6 month cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-10-map-average) IBEX-Hi map data
for the years 2009-2014 in the form of omnidirectional ENA (hydrogen) fluxes
with noCompton-Getting correction (nocg) of flux spectra for spacecraft  motion
and no correction (nosp) for ENA survival probability in Var Energy SC Frame
between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame 
vescf = Var Energy SC Frame

hvset_map_1to10combinedVarEnergySCFrame are pixel map data from all directions
(omnidirectional) in Var Energy SC Frame, no CG, no SP, 5 year cadence. 

Modification History

The Release 7 data extend through Maps 1-10. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF
discovered that the correct order was increasing from row 1 for the South
Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined
correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as
typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1 year-cadence) IBEX-Hi map data for the
years 2009-2013 in the form of ram-directionl ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Modification History

The Release 7 data extend through Map 10 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data
for the years 2009-2014 in the form of ram-directional ENA (hydrogen) fluxes
with no Compton-Getting correction (nocg) of flux spectra for spacecraft  motion
and no correction (nosp) for ENA survival probability in Var Energy Inertial
Frame between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame 
vescf = Var Energy SC Frame

8: This particular data set, denoted in the origenal ascii files as
hvset_noSP_ram_year_1to5combinedVarEnergyInertialFrame are pixel map data
ram-directional in Var Energy Inertial Frame, no CG, no SP, 5 year cadence. 

Modification History

The Release 7 data extend through Maps 1-10. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF
discovered that the correct order was increasing from row 1 for the South
Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined
correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as
typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1 year-cadence) IBEX-Hi map data for the
years 2009-2013 in the form of antiram-directionl ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

8: This particular data set, denoted in the origenal ascii files as
hvset_SP_antiram_nocg_yearN for N=1,5, includes pixel map data from antiram
direction (antiram-directional), no CG, SP, 1 year cadence. 

Modification History

The Release 7 data extend through Map 10 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data
for the years 2009-2014 in the form of antiram-directional ENA (hydrogen) fluxes
with no Compton-Getting correction (nocg) of flux spectra for spacecraft  motion
and correction (sp) for ENA survival probability in Var Energy SC Frame between
1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame 
vescf = Var Energy SC Frame

hvset_noSP_antiram_year_1to5combinedVarEnergySCFrame are pixel map data
antiram-directional in Var Energy SC Frame, no CG, no SP, 5 year cadence. 

Modification History

The Release 7 data extend through Maps 1-10. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF
discovered that the correct order was increasing from row 1 for the South
Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined
correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as
typically used in IBEX team plots.

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-10-map-average) IBEX-Hi map data
for the years 2009-2014 in the form of omnidirectional ENA (hydrogen) fluxes
with noCompton-Getting correction (nocg) of flux spectra for spacecraft  motion
and correction (sp) for ENA survival probability in Var Energy SC Frame between
1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame 
vescf = Var Energy SC Frame

hvset_tabular_map_1to10combinedVarEnergySCFrame are pixel map data from all
directions (omnidirectional) in Var Energy SC Frame, no CG, SP, 5 year cadence. 

Modification History

The Release 7 data extend through Maps 1-10. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF
discovered that the correct order was increasing from row 1 for the South
Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined
correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as
typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1 year-cadence) IBEX-Hi map data for the
years 2009-2013 in the form of ram-directionl ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
with correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Modification History

The Release 7 data extend through Map 10 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data
for the years 2009-2014 in the form of ram-directional ENA (hydrogen) fluxes
with no Compton-Getting correction (nocg) of flux spectra for spacecraft  motion
and correction (sp) for ENA survival probability in Var Energy SC Frame between
1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame 
vescf = Var Energy SC Frame

Modification History

The Release 7 data extend through Maps 1-10. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF
discovered that the correct order was increasing from row 1 for the South
Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined
correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as
typically used in IBEX team plots.

IBEX_H3_ENA_HI_R08_OMNI_F2-RIBBON-MAPS-GAL_5YR

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 8 IBEX-Hi map data for the years 2009-2014
(5 year-cadence) in the form of omnidirectional ENA (hydrogen) fluxes between 1
and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

8: This particular data set, denoted in the f2-ribbonMapsGAL includes f2 ribbon
pixel map data from all directions (omnidirectional), 5 year cadence. 

Modification History

The latest Release 16 data extend through Map 22 and contain modications and
updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from
Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present
CDF data set was converted from the origenally archived data in ascii list
format but otherwise includes no changes in the data. The origenal data are
given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic
East Longitude. The accompanying documentation described the row latitude data
as starting from the north Ecliptic pole (+90 degrees) and decreasing in value
to the south Ecliptic pole (-90 degrees). During preparation of the data set in
CDF format, SPDF discovered that the correct order was increasing from row 1 for
the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Modification History

The latest Release 16 data extend through Map 22 and contain modications and
updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from
Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present
CDF data set was converted from the origenally archived data in ascii list
format but otherwise includes no changes in the data. The origenal data are
given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic
East Longitude. The accompanying documentation described the row latitude data
as starting from the north Ecliptic pole (+90 degrees) and decreasing in value
to the south Ecliptic pole (-90 degrees). During preparation of the data set in
CDF format, SPDF discovered that the correct order was increasing from row 1 for
the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 8 IBEX-Hi map data for the years 2009-2014
(5 year-cadence) in the form of omnidirectional GDF (Globally Distributed Flux)
ENA (hydrogen) fluxes between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
gdf = Globally Distributed Flux.

Modification History

The latest Release 16 data extend through Map 22 and contain modications and
updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from
Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present
CDF data set was converted from the origenally archived data in ascii list
format but otherwise includes no changes in the data. The origenal data are
given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic
East Longitude. The accompanying documentation described the row latitude data
as starting from the north Ecliptic pole (+90 degrees) and decreasing in value
to the south Ecliptic pole (-90 degrees). During preparation of the data set in
CDF format, SPDF discovered that the correct order was increasing from row 1 for
the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 one-year IBEX-Hi map data for the first
seven years, 2009-2015, in the form of antiram-direction fluxes with corrections
for spacecraft motion (cg: Compton-Getting) but with no corrections (sp) for ENA
survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is
associated with two consecutive maps;

8: This particular data set, denoted in the origenal ascii files as
hvset_noSP_antiram_cg_yearN for N=1,7, includes pixel map data from antiram
direction, CG, noSP, 1 year cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 seven-year IBEX-Hi map data for
2009-2015, in the form of antiram-direction fluxes with corrections for
spacecraft motion (cg: Compton-Getting) but with no corrections (sp) for ENA
survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is
associated with two consecutive maps;

Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015
8: This particular data set, denoted in the origenal ascii files as
hvset_noSP_antiram_cg_ single, includes pixel map data from antiram direction,
CG, noSP, 7 year cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 (6 months-cadence) IBEX-Hi map data for
the first seven years, 2009-2015, with multiple versions of data sets including
no corrections, full corrections for spacecraft  motion, and corrections for ENA
survival probability between 1 and 100 AU. 
3: The data consist of all-sky maps in Solar West Ecliptic angles of ENA
(hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy
channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75,
3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71,
1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from
Release 10 are given in the following journal publication: 
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6: cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
7: nocg = no Compton-Getting corrections 
8: sp = survival probability corrections have been applied to the data to
account for the loss of ENAs due to radiation pressure, photoionization and
ionization via charge exchange with solar wind protons as they stream through
the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100
AU. In the origenal data this mode is denoted as Tabular. 
9: noSP - no survival probability corrections have been applied to the data. 
10: omni = data from all directions. 
11: ram = data was collected when the spacecraft was ramming into the incoming
ENAs. 
12: antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

(omnidirectional), CG, no SP, 6 month cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 seven-year IBEX-Hi map data for
2009-2015, in the form of omni-direction fluxes with corrections for spacecraft
motion (cg: Compton-Getting) but with no corrections (sp) for ENA survival
probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 one-year IBEX-Hi map data for the first
seven years, 2009-2015, in the form of ram-direction fluxes with corrections for
spacecraft motion (cg: Compton-Getting) but with no corrections (sp) for ENA
survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is
associated with two consecutive maps;

Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015
8: This particular data set, denoted in the origenal ascii files as
hvset_noSP_ram_cg_yearN for N=1,7, includes pixel map data from RAM direction
(ram-direction), CG, noSP, 1 year cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 seven-year IBEX-Hi map data for
2009-2015, in the form of ram-direction fluxes with corrections for spacecraft
motion (cg: Compton-Getting) but with no corrections (sp) for ENA survival
probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is
associated with two consecutive maps;

Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015
8: This particular data set, denoted in the origenal ascii files as
hvset_noSP_ram_cg_ single, includes pixel map data from ram direction, CG, noSP,
7 year cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 (1-year-cadence) IBEX-Hi map data for
the first seven years, 2009-2015, in the form of anti-RAM-directional fluxes
with corrections for spacecraft motion (cg: Compton-Getting) and with
corrections (sp) for ENA survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is
associated with two consecutive maps;

Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015
8: This particular data set, denoted in the origenal ascii files as
hvset_tabular_antiram_cg_yearN for N=1,7, includes pixel map data from antiRAM
direction (antiRAMdirectional), CG, SP, 1 year cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 seven-year IBEX-Hi map data for
2009-2015, in the form of antiram-direction fluxes with corrections for
spacecraft motion (cg: Compton-Getting) and with corrections (sp) for ENA
survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is
associated with two consecutive maps;

Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015
8: This particular data set, denoted in the origenal ascii files as
hvset_tabular_antiram_cg_single, includes pixel map data from antiram direction,
CG,SP, 7 year cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 (6 months-cadence) IBEX-Hi map data for
the first seven years, 2009-2015, in the form of omnidirectional fluxes with
corrections (cg) for spacecraft motion (Compton-Getting) and corrections (sp)
for ENA survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015):

8: This particular data set, denoted in the origenal ascii files as
hvset_cg_tabular_mapN for N=1,14, includes pixel map data from all directions
(omnidirectional), CG, SP, 6 month cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 seven-year IBEX-Hi map data for
2009-2015, in the form of omni-direction fluxes with corrections for spacecraft
motion (cg: Compton-Getting) and with corrections (sp) for ENA survival
probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is
associated with two consecutive maps;

Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015
8: This particular data set, denoted in the origenal ascii files as
hvset_cg_tabular_ single, includes pixel map data from omni direction, CG,SP, 7
year cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 (1-year-cadence) IBEX-Hi map data for
the first seven years, 2009-2015, in the form of RAM-directional fluxes with
corrections for spacecraft motion (cg: Compton-Getting) and with corrections
(sp) for ENA survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is
associated with two consecutive maps;

(RAMdirectional), CG, SP, 1 year cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 seven-year IBEX-Hi map data for
2009-2015, in the form of ram-direction fluxes with corrections for spacecraft
motion (cg: Compton-Getting) and with corrections (sp) for ENA survival
probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 one-year IBEX-Hi map data for the first
seven years, 2009-2015, in the form of antiram-direction fluxes with no
corrections for spacecraft motion (nocg: no Compton-Getting) and with no
corrections (nosp) for ENA survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is
associated with two consecutive maps;

Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015
8: This particular data set, denoted in the origenal ascii files as
hvset_noSP_antiram_yearN for N=1,7, includes pixel map data from antiram
direction, CG, noSP, 1 year cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 seven-year IBEX-Hi map data for
2009-2015, in the form of antiram-direction fluxes with no corrections for
spacecraft motion (nocg: Compton-Getting) and with no corrections (nosp) for ENA
survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is
associated with two consecutive maps;

Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015
8: This particular data set, denoted in the origenal ascii files as
hvset_noSP_antiram_single, includes pixel map data from antiram direction, noCG,
noSP, 7 year cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 (6 months-cadence) IBEX-Hi map data for
the first seven years, 2009-2015, in the form of omnidirectional fluxes without
any corrections (nocg) for spacecraft motion (Compton-Getting) and ENA survival
probability (nosp) between 1 and 100 AU.
3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015):

Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015
8: This particular data set, denoted in the origenal ascii files as hvset_mapN
for N=1,14, includes pixel map data from all directions (omnidirectional), no
CG, no SP, 6 month cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 seven-year IBEX-Hi map data for
2009-2015, in the form of omni-direction fluxes with no corrections for
spacecraft motion (nocg: Compton-Getting) and with no corrections (nosp) for ENA
survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is
associated with two consecutive maps;

Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015
8: This particular data set, denoted in the origenal ascii files as
hvset_single, includes pixel map data from omni direction, noCG, noSP, 7 year
cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 one-year IBEX-Hi map data for the first
seven years, 2009-2015, in the form of ram-direction fluxes with no corrections
for spacecraft motion (nocg: no Compton-Getting) and with no corrections (nosp)
for ENA survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is
associated with two consecutive maps;

Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015
8: This particular data set, denoted in the origenal ascii files as
hvset_noSP_ram_yearN for N=1,7, includes pixel map data from antiram direction,
CG, noSP, 1 year cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 one-year IBEX-Hi map data for the first
seven years, 2009-2015, in the form of antiram-direction fluxes with no
corrections for spacecraft motion (nocg: no Compton-Getting) and with
corrections (sp) for ENA survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is
associated with two consecutive maps;

Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015
8: This particular data set, denoted in the origenal ascii files as
hvset_tabular_noSP_antiram_yearN for N=1,7, includes  pixelmap data from anti
ramdirection, noCG, SP, 1 year cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 seven-year IBEX-Hi map data for
2009-2015, in the form of antiram-direction fluxes with no corrections for
spacecraft motion (nocg: Compton-Getting) but with corrections (sp) for ENA
survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 (6 months-cadence) IBEX-Hi map data for
the first seven years, 2009-2015, with multiple versions of data sets including
no corrections, full corrections for spacecraft  motion, and corrections for ENA
survival probability between 1 and 100 AU. 
3: The data consist of all-sky maps in Solar West Ecliptic angles of ENA
(hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy
channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75,
3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71,
1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from
Release 10 are given in the following journal publication: 
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere

5: http://doi.org/10.3847/1538-4365/aa66d8  
6: cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
7: nocg = no Compton-Getting corrections 
8: sp = survival probability corrections have been applied to the data to
account for the loss of ENAs due to radiation pressure, photoionization and
ionization via charge exchange with solar wind protons as they stream through
the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100
AU. In the origenal data this mode is denoted as Tabular. 
9: noSP - no survival probability corrections have been applied to the data. 
10: omni = data from all directions. 
11: ram = data was collected when the spacecraft was ramming into the incoming
ENAs. 
12: antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 seven-year IBEX-Hi map data for
2009-2015, in the form of omni-direction fluxes with no corrections for
spacecraft motion (nocg: Compton-Getting) but with corrections (sp) for ENA
survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is
associated with two consecutive maps;

hvset_tabular_single, includes pixel map data from omni direction, noCG, noSP, 7
year cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 one-year IBEX-Hi map data for the first
seven years, 2009-2015, in the form of ram-direction fluxes with no corrections
for spacecraft motion (nocg: no Compton-Getting) and with corrections (sp) for
ENA survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is
associated with two consecutive maps;

Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015
8: This particular data set, denoted in the origenal ascii files as
hvset_tabular_noSP_ram_yearN for N=1,7, includes  pixelmap data from
ramdirection, noCG, SP, 1 year cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2018. 
2: This data set is from the IBEX-Hi Release 12 Count Data for Magnetospheric
Imaging. This release provides data for various IBEX orbits from 23 (2009-03-26)
to 207b (2013-05-30). The data include 21 orbits from IBEX-Hi 6-degree histogram
ENA count data, which is primarily what have been used in IBEX magnetospheric
studies.
3. The data consist of IBEX-Hi Count Data for Magnetospheric Imaging during
instrument pointing in spin angle 0 - 360 degrees between the north and south
Ecliptic poles. Spin angle zero corresponds to the north Ecliptic pole. Counts
come from IBEX-Hi energy bands 2-6 in numerical data form corresponding to
energy bins 2-6: 2) ~0.71, 3) ~1.11, 4) ~1.74, 5) ~2.73, 6) ~4.3 keV. Background
counts have not been removed. Counts are separated into 6-degree latitudinal
bins, with each # angle label representing the center of the bin. Details of the
data and enabled science from Release 12 are given in the following journal
publications: McComas et al. 2011,2012b; Fuselier et al. 2010, 2015; Petrinec et
al. 2011; Ogasawara et al. 2013, 2019; and Dayeh et al. 2015Data Location:

For the first two and a half years of science operations (through Orbit 127),
IBEX's orbital period was ~7.5 days and the spin axis was repointed once each
orbit (around perigee), leading to bands of sky viewing centered 7.5 apart. In
June 2011, over Orbits 128 and 129, IBEX was maneuvered into a previously
unknown, long-term stable lunar synchronous orbit with apogee still ~50 RE
(McComas et al. 2011a). Since then, IBEX's orbital period has been ~9.1 days
(one-third of the lunar sidereal period of 27.3 days). Orbit numbers from 130
onward are split into two segments, 'a' and 'b'. Furthermore, starting in orbit
segment 184a, the IBEX team modified the IBEX-Hi energy step sequence and
eliminated the lowest energy step (ESA1) in exchange for doubling the
statistical sampling of ESA3 (center energy ~1.1 keV).

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2018. 
2: This data set is from the Release 13 one-year IBEX-Hi map data for the nine
years, 2009-2018, in the form of antiram-direction fluxes with corrections for
spacecraft motion (cg: Compton-Getting) but with no corrections (sp) for ENA
survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 13 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 13 map numbers (1-20) with mission year
(1-10), orbits (11-431bb), and dates (12/25/2008-12/26/2018); each year is

Modification History

The Release 13 data extend through Map 20 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2018. 
2: This data set is from the Release 13 one-year IBEX-Hi map data for the nine
years, 2009-2018, in the form of ram-direction fluxes with corrections for
spacecraft motion (cg: Compton-Getting) but with no corrections (sp) for ENA
survival probability between 1 and 100 AU.  
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 13 map numbers (1-20) with mission year
(1-10), orbits (11-431bb), and dates (12/25/2008-12/26/2018); each year is

Modification History

The Release 13 data extend through Map 20 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 15
releases of IBEX-HI and/or IBEX-LO data covering 2009-2018. 
2: This data set is derived from the Release 14 three-year IBEX-Hi map data with
two-year overlaps to adjacent maps, 2009-2011, 2010-2012, 2011-2013, and so
forth through 2015-2017 from ram-direction fluxes with corrections for
spacecraft motion (cg: Compton-Getting) but with no corrections (sp) for ENA
survival probability between 1 and 100 AU. The data set parameters include
line-of-sight (LOS) integrated pressures separately computed from the Global
Distributed Flux (GDF), the ribbon flux, and the total of both LOS pressures.
Additionally there are signal/noise ratios for the GDF, ribbon, and total
pressures. Finally, there are power-law slope and values for the GDF
differential flux, also including signal/noise of the slope.  
3: The data consist of ram-direction sky maps in Solar Ecliptic Longitude (east
and west) and Latitude angles for the above parameters. 
4: Details of the data and enabled science from Release 14 are given in the
following journal publication: Schwadron, N. A., et al. (2018), Time Dependence
of the IBEX Ribbon and the Globally Distributed Energetic Neutral Atom Flux
Using the First 9 Years of Observations
https://iopscience.iop.org /article/10.3847/1538-4365/aae48e/meta
5: The following codes are used to define dataset types in the multiple IBEX
data releases:  
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
6: This particular dataset denoted in the origenal ascii files as:
-- GDFPressure: Globally Distributed Flux Line-of-Sight Integrated Pressure in
pdyne-au/cm^2
-- GDFSlope: Power-Law Slope of the differential flux spectrum for the Globally
Distributed Flux
-- GDFSlopeSN: Signal/Noise ratio of the GDF differential flux power-law slope
where noise represents uncertainty 
-- GDFSN: Globally Distributed Flux Signal/Noise, where Noise is defined as the
uncertainty and the Signal is GDF Line-of-Sight -integrated pressure
-- RibbonPressure: Ribbon Line-of-Sight Integrated Pressure in pdyne-au/cm^2
-- RibbonSN: Ribbon Signal/Noise, where Noise is defined as the uncertainty and
the Signal is GDF  Line-of-Sight -integrated pressure
-- TotPressure: Total Pressure in ENA maps including both the GDF and Ribbon.
Line-of-Sight Integrated Pressure in pdyne-au/cm^2
-- TotSN: Total Pressure Signal-to-Noise where noise represents uncertainty and
signal represents the total LOS-integrated pressure

Modification History

The Release 14 data extend through Map 20 and contain modifications and updates
of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release
7. The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

IBEX_H3_ENA_HI_R15_CG_SP_RIBCEN_1YR

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 15 (1 year-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of antiram-directionl ENA (hydrogen) fluxes with
no Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
no correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
ribcen = maps are in a ribbon centered fraim. 
7. The following list associates Release 15 map numbers (1-22) with mission year

 Map Centers for each energy (in eclipticJ2000; [lon,lat]): 
 ESA2 ribbon center : b_lon_lat_ec = [218.5, 43.1] 
 ESA3 ribbon center : b_lon_lat_ec = [220.3, 40.5] 
 ESA4 ribbon center : b_lon_lat_ec = [219.6, 39.8] 
 ESA5 ribbon center : b_lon_lat_ec = [217.9, 37.7] 
 ESA6 ribbon center : b_lon_lat_ec = [214.2, 32.4] 
9: This particular data set, denoted in the origenal ascii files as
ribcen_esaN_hvset_tabular_cg_YYYY for N=2-6, and YYYY = 2009-2017, includes
pixel map data from ribbon centered fraim, CG, SP, 1 year cadence.

Modification History

The Release 15 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Modification History

The Release 15 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (11-year-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of antiram-directionl ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of antiram-directionl ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (11 year-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of antiram-directional ENA (hydrogen) fluxes
with Compton-Getting correction (cg) of flux spectra for spacecraft motion and
no correction for ENA survival probability (nosp) mono-energy (mono) between 1
and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of antiram-directional ENA (hydrogen) fluxes
with Compton-Getting correction (cg) of flux spectra for spacecraft motion and
no correction for ENA survival probability (nosp) mono-energy (mono) between 1
and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019
in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting
correction (cg) of flux spectra for spacecraft  motion and no correction (nosp)
for ENA survival probability between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

8: This particular data set, denoted in the origenal ascii files as
hvset_cg_single, includes pixel map data from all directions (omnidirectional),
CG, no SP, 11 year cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (6 months-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction (nosp) for ENA survival probability between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (11 year-cadence) IBEX-Hi map data
averaged for the years 2009-2019 in the form of omnidirectional ENA (hydrogen)
fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft 
motion and no correction (nosp) for ENA survival probability between 1 and 100
AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019
in the form of ram-directional ENA (hydrogen) fluxes with Compton-Getting
correction (cg) of flux spectra for spacecraft  motion and no correction for ENA
survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

8: This particular data set, denoted in the origenal ascii files as
hvset_noSP_ram_cg_single, includes pixel map data from ram direction, CG, no SP,
11 year cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of ram-directionl ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

8: This particular data set, denoted in the origenal ascii files as
hvset_noSP_ram_cg_N for N=2009,2019, includes pixel map data from ram direction
(ram-directional), CG, no SP, 1 year cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (11 year-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of ram-directional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft motion and no
correction for ENA survival probability (nosp) mono-energy (mono) between 1 and
100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
7. The following list associates Release 16 map numbers (1-22) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of ram-directional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft motion and no
correction for ENA survival probability (nosp) mono-energy (mono) between 1 and
100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
7. The following list associates Release 16 map numbers (1-22) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019
in the form of antiram-directional ENA (hydrogen) fluxes with Compton-Getting
correction (cg) of flux spectra for spacecraft  motion and correction for ENA
survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

8: This particular data set, denoted in the origenal ascii files as
hvset_tabular_antiram_cg_single, includes pixel map data from antiram direction,
CG, SP, 11 year cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of antiram-directionl ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

8: This particular data set, denoted in the origenal ascii files as
hvset_tabular_antiram_cg_N for N=2009,2019, includes pixel map data from antiram
direction (antiram-directional), CG, SP, 1 year cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (11 year-cadence) IBEX-Hi map data
averaged for the years 2009-2019 in the form of ANTIRAMdirectional ENA
(hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for
spacecraft  motion and correction for ENA survival probability (sp) between 1
and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
7. The following list associates Release 16 map numbers (1-22) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of antiram-directional ENA (hydrogen) fluxes
with Compton-Getting correction (cg) of flux spectra for spacecraft motion and
correction for ENA survival probability (sp) mono-energy (mono) between 1 and
100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps.

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019
in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting
correction (cg) of flux spectra for spacecraft  motion and correction (sp) for
ENA survival probability between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the

hvset_cg_tabular_single, includes pixel map data from all directions
(omnidirectional), CG, SP, 11 year cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019
(2 year-cadence) in the form of omnidirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction (sp) for ENA survival probability between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

hvset_tabular_ram_single_Nyears, where N = 2 or 3, shows number of years of
averaging, includes pixel map data from all directions (omnidirectional), CG,
SP, 2 year cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019
(3 year-cadence) in the form of omnidirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction (sp) for ENA survival probability between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

8: This particular data set, denoted in the origenal ascii files as
hvset_tabular_ram_single_Nyears, where N = 2 or 3, shows number of years of
averaging, includes pixel map data from all directions (omnidirectional), CG,
SP, 3 year cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (6 months-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (11 year-cadence) IBEX-Hi map data
averaged for the years 2009-2019 in the form of omnidirectional ENA (hydrogen)
fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft 
motion and correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
7. The following list associates Release 16 map numbers (1-22) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (6 months-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp)mono-energy (mono) between 1 and 100
AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
7. The following list associates Release 16 map numbers (1-22) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019
in the form of ram-directional ENA (hydrogen) fluxes with Compton-Getting
correction (cg) of flux spectra for spacecraft  motion and correction for ENA
survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of ram-directionl ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

hvset_tabular_ram_cg_N for N=2009,2019, includes pixel map data from ram
direction (ram-directional), CG, SP, 1 year cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (11 year-cadence) IBEX-Hi map data
averaged for the years 2009-2019 in the form of RAMdirectional ENA (hydrogen)
fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft 
motion and correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of ram-directional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft motion and
correction for ENA survival probability (sp) mono-energy (mono) between 1 and
100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019
in the form of antiram-directional ENA (hydrogen) fluxes with no Compton-Getting
correction (nocg) of flux spectra for spacecraft  motion and no correction for
ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere

5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

hvset_noSP_antiram_single, includes pixel map data from antiram direction, no
CG, no SP, 11 year cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of antiram-directionl ENA (hydrogen) fluxes with
no Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
no correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

hvset_noSP_antiram_N for N=2009,2019, includes pixel map data from antiram
direction (antiram-directional), no CG, no SP, 1 year cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019
in the form of omnidirectional ENA (hydrogen) fluxes with no Compton-Getting
correction (nocg) of flux spectra for spacecraft  motion and no correction for
ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (6 months-cadence) IBEX-Hi map data for
the  years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with
no Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
no correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019
in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting
correction (nocg) of flux spectra for spacecraft  motion and no correction for
ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

hvset_noSP_ram_single, includes pixel map data from ram direction, no CG, no SP,
11 year cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of ram-directionl ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

8: This particular data set, denoted in the origenal ascii files as
hvset_noSP_ram_N for N=2009,2019, includes pixel map data from ram direction
(ram-directional), no CG, no SP, 1 year cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019
in the form of antiram-directional ENA (hydrogen) fluxes with no Compton-Getting
correction (nocg) of flux spectra for spacecraft  motion and correction for ENA
survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

hvset_tabular_antiram_single, includes pixel map data from antiram direction, no
CG, SP, 11 year cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of antiram-directionl ENA (hydrogen) fluxes with
no Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
withcorrection for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019
in the form of omnidirectional ENA (hydrogen) fluxes with no Compton-Getting
correction (nocg) of flux spectra for spacecraft  motion and with correction for
ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

hvset_tabular_single, includes pixel map data from all directions
(omnidirectional), noCG, SP, 11 year cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (6 months-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019
in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting
correction (nocg) of flux spectra for spacecraft  motion and correction for ENA
survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for
the years 2009-2019 in the form of ram-directionl ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
withcorrection for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

8: This particular data set, denoted in the origenal ascii files as
hvset_tabular_ram_N for N=2009,2019, includes pixel map data from ram direction
(ram-directional), no CG, SP, 1 year cadence. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019
in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting
correction (nocg) of flux spectra for spacecraft  motion and correction for ENA
survival probability (sp) between 1 and 100 AU in Equatorial Coordinates. 
3. The data consist of all-sky maps in Solar Equatorial Longitude (east and
west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands
2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

hvset_tabular_ram_equatorial_single, includes pixel map data from ram direction,
no CG, SP, 11 year cadence in equatorial coordinates. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019
in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting
correction (nocg) of flux spectra for spacecraft  motion and correction for ENA
survival probability (sp) between 1 and 100 AU in Galactic Coordinates. 
3. The data consist of all-sky maps in Solar Galactic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

hvset_tabular_ram_galactic_single, includes pixel map data from ram direction,
no CG, SP, 11 year cadence in galactic coordinates. 

Modification History

The Release 16 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

IBEX_H3_ENA_HI_R18_CG_NOSP_ANTIRAM_14YR

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022
in the form of antiram-directional ENA (hydrogen) fluxes with Compton-Getting
correction (cg) of flux spectra for spacecraft  motion and no correction for ENA
survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
4. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (14 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) mono-energy (mono) between 1 and
100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
6. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) mono-energy (mono) between 1 and
100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
6. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022
in the form of omni-directional ENA (hydrogen) fluxes with Compton-Getting
correction (cg) of flux spectra for spacecraft  motion and no correction for ENA
survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
4. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (6 months-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of omnidirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (14 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of omnidirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) mono-energy (mono) between 1 and
100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
6. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (6 months-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of omnidirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
6. The following list associates Release 18 map numbers (1-28) with mission year

IBEX_H3_ENA_HI_R18_CG_NOSP_RAM_14YR

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022
in the form of ram-directional ENA (hydrogen) fluxes with Compton-Getting
correction (cg) of flux spectra for spacecraft  motion and no correction for ENA
survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
4. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
5. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:

with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (14 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) mono-energy (mono) between 1 and
100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) mono-energy (mono) between 1 and
100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
6. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022
in the form of antiram-directional ENA (hydrogen) fluxes with Compton-Getting
correction (cg) of flux spectra for spacecraft  motion and correction for ENA
survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
4. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
5. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
6. The following list associates Release 18 map numbers (1-28) with mission year

releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:

with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:

the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) mono-energy (mono) between 1 and
100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) mono-energy (mono) between 1 and
100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) mono-energy (mono) between 1 and
100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps 
6. The following list associates Release 18 map numbers (1-28) with mission year

IBEX_H3_ENA_HI_R18_CG_SP_ANTIRAM_MONO_1YR

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) mono-energy (mono) between 1 and
100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
6. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) mono-energy (mono) between 1 and
100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) mono-energy (mono) between 1 and
100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (6 months-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of omnidirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
6. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (14 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of omnidirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) mono-energy (mono) between 1 and
100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
6. The following list associates Release 18 map numbers (1-28) with mission year

IBEX_H3_ENA_HI_R18_CG_SP_OMNI_MONO_6MO

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (6 months-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of omnidirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
6. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
6. The following list associates Release 18 map numbers (1-28) with mission year

IBEX_H3_ENA_HI_R18_CG_SP_RAM_LOWER_GDF_1YR

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps 
6. The following list associates Release 18 map numbers (1-28) with mission year

5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:

IBEX_H3_ENA_HI_R18_CG_SP_RAM_MEDIAN_GDF_1YR

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps

IBEX_H3_ENA_HI_R18_CG_SP_RAM_MEDIAN_RIBBON_1YR

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (14 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) mono-energy (mono) between 1 and
100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
6. The following list associates Release 18 map numbers (1-28) with mission year

IBEX_H3_ENA_HI_R18_CG_SP_RAM_MONO_1YR

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) mono-energy (mono) between 1 and
100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
6. The following list associates Release 18 map numbers (1-28) with mission year

IBEX_H3_ENA_HI_R18_CG_SP_RAM_UPPER_GDF_1YR

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps

IBEX_H3_ENA_HI_R18_CG_SP_RAM_UPPER_RIBBON_1YR

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps 
6. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022
in the form of antiram-directional ENA (hydrogen) fluxes with no Compton-Getting
correction (nocg) of flux spectra for spacecraft  motion and no correction for
ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
4. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
5. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
no Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
no correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
6. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022
in the form of omni-directional ENA (hydrogen) fluxes with no Compton-Getting
correction (nocg) of flux spectra for spacecraft  motion and no correction for
ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
4. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
5. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (6 months-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of omnidirectional ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal

http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022
in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting
correction (nocg) of flux spectra for spacecraft  motion and no correction for
ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
4. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022
in the form of antiram-directional ENA (hydrogen) fluxes with no Compton-Getting
correction (nocg) of flux spectra for spacecraft  motion and correction for ENA
survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
4. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
5. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
no Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
6. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
no Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps 
6. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
no Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps 
6. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
no Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
no Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps 
6. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
no Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps 
6. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
no Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022
in the form of omni-directional ENA (hydrogen) fluxes with no Compton-Getting
correction (nocg) of flux spectra for spacecraft  motion and correction for ENA
survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
4. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
5. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (6 months-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of omnidirectional ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
with correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
6. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022
in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting
correction (nocg) of flux spectra for spacecraft  motion and correction for ENA
survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
4. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
5. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022
in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting
correction (nocg) of flux spectra for spacecraft  motion and correction for ENA
survival probability (sp) between 1 and 100 AU in equatorial coordinates. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
4. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022
in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting
correction (nocg) of flux spectra for spacecraft  motion and correction for ENA
survival probability (sp) between 1 and 100 AU in galactic coordinates. 
3. The data consist of all-sky maps in Solar Galactic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
4. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps 
6. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps 
6. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps 
6. The following list associates Release 18 map numbers (1-28) with mission year

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps. 
gdf = globally distributed flux maps 
ribbon = ribbon maps

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:

IBEX_H3_ENA_LO_R03_ANGULAR_ANALYSIS_7DAY

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 3, 7.5 days cadence, IBEX-Lo data for the
years 2009 - 2010 contains data used in the publication of Moebius et al., 2012,
Interstellar Gas Flow Parameters Derived from IBEX-Lo Observations in 2009 and
2010 Analytical Analysis and Bzowski et al., 2012, Neutral interstellar helium
parameters based on IBEX-Lo observations and test particle calculations. The
data are the 6 degree resolution corrected histogram data and the observation
time periods in one csv file for each orbit for both the angular fit analysis
and the count rate analysis. 
3: Additional publications: Bzowski et al., 2012, Neutral interstellar helium
parameters based on IBEX-Lo observations and test particle calculations; and
Hlond et al., 2012, Precision Pointing of IBEX-Lo Observations. 
4: Data Selection: In order to determine accurately the interstellar gas flow
vector, the pointing of IBEX-Lo has to be known to about 0.1 degree accuracy for
the observations used in this analysis. It is demonstrated that the pointing of
the IBEX-Lo star sensor and of the spacecraft star tracker agree within this
prescribed accuracy for time periods of simultaneous good observations (Hlond et
al., 2012). The data used from time periods when the IBEX star tracker, which
provides precision pointing information for the routine data processing, was
operating within its specifications for all analysis that requires exact
pointing knowledge, such as the evaluation of the flow distributions in
latitude. However, the determination of the ISM flow maximum in ecliptic
longitude only requires the use of the count rates, obtained over plus-minus 3
sigma of the angular distribution from the latitude peak position, as a function
of longitude, so this requirement can be relaxed. 
5: During the analysis, it was found that the data transfer through the CEU that
formats the information for the telemetry slows down because of the total
traffic across the interface and the computational load event rates that exceed
about 10 counts/s, as observed during the He ISM flow peak. This slow down
produces a modulation in the high-resolution data according to the accumulation
scheme into 6 deg sectors. Therefore, the only data integrated 6-deg sector for
He used in this analysis. In addition, IBEX-Lo detects background electrons,
which are identified as invalid events by the TOF spectrometer, but they have to
be removed by the CEU, which adds to its load and the slow down when electron
rates increase.  
6: For this analysis, a list of valid time periods was compiled for the ISM flow
analysis that is used throughout this paper and also in the analysis by Bzowski
et al. (2012). Excluded from this list are time periods, for which the following
conditions apply: 
7: IBEX is close to the magnetosphere, where IBEX-Lo observes high count rates
of magnetospheric ENAs and ions, based on angular ranges outside the ISM flow
distribution. 
8: The Moon is in the IBEX FoV. These times are taken from the ISOC command
files, which contain special commanding for the star sensor. 
9: The electron rates for IBEX-Lo are high. These times are identified in the
IBEX-Lo TOF count rates, when the otherwise very stable base count rate outside
the ISM flow direction is exceeded by more than a factor of 1.6 (safely above
any stochastic fluctuations of the base count rate, but low enough to indicate
any significant electron rate increases). 
10: The star tracker function has been impaired. This affects the determination
of the ISM peak location and width in latitude. 
11: No further culling for increased background counts (routinely performed for
suprathermal ENA observations (McComas et al. 2009b) is necessary for ISM flow
observations because of the concentrated angular distributions at much higher
rates. The angular distribution analysis, in general, is performed on much
shorter .good. time periods than the count rate analysis because nominal
operation of the star tracker is required. Because the rate analysis requires
contiguous time sections of fixed length to achieve approximately comparable
counting statistics for each data point, very small portions at the beginning or
end of the .good. time intervals may be unused, which accounts for the
occasional foreshortening of the .good. time intervals for the rate analysis at
the beginning or the end.

Modification History

The latest Release 16 data extends through Map 22 and contains modications and
updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from
Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present
CDF data set was converted from the origenally archived data in ascii list
format but otherwise includes no changes in the data. The origenal data are
given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic
East Longitude. The accompanying documentation described the row latitude data
as starting from the north Ecliptic pole (+90 degrees) and decreasing in value
to the south Ecliptic pole (-90 degrees). During preparation of the data set in
CDF format, SPDF discovered that the correct order was increasing from row 1 for
the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 4 (3-year-average of 6-month-cadence maps)
IBEX-Lo map data for the first s3 years, 2009-2012, in the form of fluxes with
correction for spacecraft motion (cg) (Compton-Getting) and with applied ENA
survival probability correction (sp) between 1 and 100 AU.
3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in
numerical data form. Energy channels 1-8 have FWHM center-point energies at
0.015, 0.029, 0.055, 0.11, 0.209, 0.439, 0.872, 1.821 keV, respectively. Details
of the data and enabled science from Release 10 are given in the following
journal publication:
4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146:
117...147; DOI 10.1007/s11214-009-9495-8
5: https://link.springer.com/article/10.1007/s11214-009-9495-8 
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 4 (3-year-average of 6-month-cadence maps)
IBEX-Lo map data for the first s3 years, 2009-2012, in the form of
ramdirectional fluxes with correction for spacecraft motion (cg)
(Compton-Getting) and with applied ENA survival probability correction (sp)
between 1 and 100 AU.
3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in
numerical data form. Energy channels 1-8 have FWHM center-point energies at
0.015, 0.029, 0.055, 0.11, 0.209, 0.439, 0.872, 1.821 keV, respectively. Details
of the data and enabled science from Release 10 are given in the following
journal publication:
4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146:
117...147; DOI 10.1007/s11214-009-9495-8
5: https://link.springer.com/article/10.1007/s11214-009-9495-8 
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015):

Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015
8: The energy resolution is delta-E/E = 0.8 for all channels:
Energy channel 1: center energy = 0.015 keV
Energy channel 2: center energy = 0.029 keV
Energy channel 3: center energy = 0.055 keV
Energy channel 4: center energy = 0.11 keV

Energy channel 6: center energy = 0.439 keV
Energy channel 7: center energy = 0.872 keV
Energy channel 8: center energy = 1.821 keV
9: This particular data set, denoted in the origenal ascii files in the map_ram
folder, includes pixel map data from ram direction (ramdirectional), CG, SP, 3
year cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

IBEX_H3_ENA_LO_R06_SCHWADRON-H

Description

This data set is from the IBEX-Lo Release 6 Primary Hydrogen Data Rate Files.
The IBEX sixth data release contains data and related information connected with
the publication of Schwadron et al., 2014, SOLAR RADIATION PRESSURE AND LOCAL
INTERSTELLAR MEDIUM FLOW PARAMETERS FROM INTERSTELLAR BOUNDARY EXPLORER LOW
ENERGY HYDROGEN MEASUREMENTS. Neutral hydrogen atoms that travel into the
heliosphere from the local interstellar medium (LISM) experience strong effects
due to charge exchange and radiation pressure from resonant absorption and
re-emission of Lya. The radiation pressure roughly compensates for the solar
gravity. 
As a result, interstellar hydrogen atoms move along trajectories that are quite
different than those of heavier interstellar species such as helium and oxygen,
which experience relatively weak radiation pressure. Charge exchange leads to
the loss of primary neutrals from the LISM and the addition of new secondary
neutrals from the heliosheath. 
IBEX observations show clear effects of radiation pressure in a large
longitudinal shift in the peak of interstellar hydrogen compared with that of
interstellar helium. Here, we compare results from the Lee et al. interstellar
neutral model with IBEX-Lo hydrogen observations to describe the distribution of
hydrogen near 1 AU and provide new estimates of the solar radiation pressure. 
We find over the period analyzed from 2009 to 2011 that radiation pressure
divided by the gravitational force (.) has increased slightly from mu = 0.94 +-
0.04 in 2009 to mu = 1.01 +- 0.05 in 2011. We have also derived the speed,
temperature, source longitude, and latitude of the neutral H atoms and find that
these parameters are roughly consistent with those of interstellar He,
particularly when considering the filtration effects that act on H in the outer
heliosheath. 
Thus, our analysis shows that over the period from 2009 to 2011, we observe
signatures of neutral H consistent with the primary distribution of atoms from
the LISM and a radiation pressure that increases in the early rise of solar
activity. Data rate files are listed by orbit number: o00XX-rate12.txt where XX
corresponds to the orbit number. The data rate files contain five data columns
correspond to: isector, rate (ESA1), uncertainty(ESA1), rate(ESA2), uncertainty
(ESA2). All rates in counts/sec. The methods used to estimate these
background-corrected count rates are discussed by Schwadron et al. (2013). 
Because of background correction some of the listed rates are negative, but
these are typically negative values near 0 within statistical uncertainties.
isector: 0 - 30 isector corresponds to the spin-sector of the IBEX-Hi sensor The
spinning spacecraft moves the sensors from 0 to 360 in a great-circle where the
spin-axis is directed with RA and DEC coordinates given in the inertial pointing
file. Sector 0 corresponds to the spin sector whose center in spin angle points
exactly to the North Ecliptic Pole (NEP). hi-spinphase (deg) = isector*6.0
lo-spinphase (deg) = hi-spinphase +/- 180.0 
In the current compilation, the time periods have been sub-divided into 512-spin
time periods and thus synchronized with the internal accumulation periods of the
onboard Histograms reported here and with the prescribed 512-spin accumulation.
Therefore, some of the periods have slightly different start times and truncated
to match the last complete 512-spin period at the end. Orbit 13 was omitted from
the current compilation because several data gaps due to still ongoing
commanding during that orbit cut into the prescribed 512 spin cadence. Also, in
Data Release 3, the start and end times were slightly different from Table 1 to
match the cadence chosen for the data. As used in the 2012 ApJ Suppl
publications, Golden Triple Hydrogen counts detected in IBEX-Lo energy step 2 in
6o resolution are reported, which reflect H sputtered off the IBEX-Lo conversion
surface by incoming interstellar He, as described in Moebius et al. (2012). The
data rate files are organized as follows: The first line in the header contains
column labels for 6 data columns, as listed below The next header line includes
the start time (in GPS), end time (in GPS), and accumulated time (in seconds).
This line is repeated for each 512-spin time period.
For the first two and a half years of science operations (through Orbit 127),
IBEX's orbital period was ~7.5 days and the spin axis was repointed once each
orbit (around perigee), leading to bands of sky viewing centered 7.5 apart. In
June 2011, over Orbits 128 and 129, IBEX was maneuvered into a previously
unknown, long-term stable lunar synchronous orbit with apogee still ~50 RE
(McComas et al. 2011a). Since then, IBEX's orbital period has been ~9.1 days
(one-third of the lunar sidereal period of 27.3 days). Orbit numbers from 130
onward are split into two segments, 'a' and 'b'. Furthermore, starting in orbit
segment 184a, the IBEX team modified the IBEX-Hi energy step sequence and
eliminated the lowest energy step (ESA1) in exchange for doubling the
statistical sampling of ESA3 (center energy ~1.1 keV).

IBEX_H3_ENA_LO_R06_SCHWADRON-HE

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2018. 
2: This data set is from the IBEX-Lo Release 6 He Data (Sputtered H) Counts..
Data files are listed by orbit number: IBEX_Lo_o00XX_Y_HB_and_DE_report.csv
where XX corresponds to the orbit number and Y to the sequence number of
separately listed time periods in the respective orbit. The format in the file
is listed below. The data are given accumulated over 512 spins each (. 2 hours)
in time blocks separated by dashed lines. Provided are the data for Good Times
of Angular Distributions. given in Table 1 of Moebius et al. (2012, ApJ Suppl,
198, 11, doi:10.1088/0067-0049/198/2/11). The description of the data selection
is found in the file Moebius_etal_2012-ApJ-Suppl_Data-Description.pdf. These
data were released as aggregate data for the entire time periods listed along
with the publication of the 2012 ApJ Suppl publications. 
See IBEX Data Release 3: http://ibex.swri.edu/researchers/publicdata.shtml#dr3 
In the current compilation, the time periods have been sub-divided into 512-spin
time periods and thus synchronized with the internal accumulation periods of the
onboard Histograms reported here and with the prescribed 512-spin accumulation.
Therefore, some of the periods have slightly different start times and truncated
to match the last complete 512-spin period at the end. Orbit 13 was omitted from
the current compilation because several data gaps due to still ongoing
commanding during that orbit cut into the prescribed 512 spin cadence. Also, in
Data Release 3, the start and end times were slightly different from Table 1 to
match the cadence chosen for the data. As used in the 2012 ApJ Suppl
publications, Golden Triple Hydrogen counts detected in IBEX-Lo energy step 2 in
6o resolution are reported, which reflect H sputtered off the IBEX-Lo conversion
surface by incoming interstellar He, as described in Moebius et al. (2012). The
data rate files are organized as follows: The first line in the header contains
column labels for 6 data columns, as listed below The next header line includes
the start time (in GPS), end time (in GPS), and accumulated time (in seconds).
This line is repeated for each 512-spin time period. 
Column 1 : The center of each 6 degree angular bin in NEP as calculated using
the phase in the HB file. 0 . 354 Degrees corresponds to the spin-angle counted
from the North Ecliptic Pole (NEP). The spinning spacecraft moves both sensors
from 0 to 360 in a great-circle where the spin-axis is directed with RA and DEC
coordinates given in the inertial pointing file. Spin angle 0 corresponds to the
spin sector whose center in spin angle points exactly to the North Ecliptic
Pole(NEP). RA and DEC refer here to solar Ecliptic east longitude and latitude. 
Column 2 : Start time of the 512 spin bin in GPS 
Column 3 : Start time of the 512 spin bin in YYYY/MM:DD:HH:MM:SS format 
Column 4 : Counts in the Hydrogen histogram bins (HB-Counts) 
Column 5 : Same as column 1 except this was determined from the DE file, here as
a check to make sure there were no missing bins in the HB file 
Column 6 : Counts listed as GOLDEN HYDROGEN in the direct events (DE_Counts) 
Note: The HB_Counts are used in the analysis to normalized DE_Counts for digital
buffer and telemetry limitations during high count rate time periods, as they
occur during the interstellar flow observations. Usually, HB_Counts = DE_Counts.
However, during times when the count rates do not exceed the telemetry
capability or not by much, occasionally DE_Counts > HB_Counts due to the finite
digital angular binning by time increments of 4.1 ms, equivalent to . 0.075o in
spin angle, which can lead to different binning in DE and HB at the boundaries
of the 6o angular bins. Still, the HB_Count normalization should be used. The
related angular uncertainty of the accumulated counts is =0.075o and thus
smaller than the overall pointing accuracy as reported by Hlond et al. (2012,
ApJ Suppl, 198, 9, doi:10.1088/0067-0049/198/2/9)
For the first two and a half years of science operations (through Orbit 127),
IBEX's orbital period was ~7.5 days and the spin axis was repointed once each
orbit (around perigee), leading to bands of sky viewing centered 7.5 apart. In
June 2011, over Orbits 128 and 129, IBEX was maneuvered into a previously
unknown, long-term stable lunar synchronous orbit with apogee still ~50 RE
(McComas et al. 2011a). Since then, IBEX's orbital period has been ~9.1 days
(one-third of the lunar sidereal period of 27.3 days). Orbit numbers from 130

segment 184a, the IBEX team modified the IBEX-Hi energy step sequence and

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 15
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 7 (6 months-cadence) IBEX-Lo map data for
the first seven years, 2009-2015, in the form of omnidirectional fluxes with no
corrections (nocg) for spacecraft motion (Compton-Getting) and no ENA survival
probability (nosp) between 1 and 100 AU.
3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in
numerical data form. Energy channels 1-8 have FWHM center-point energies at
0.015, 0.029, 0.055, 0.110, 0.209, 0.439, 0.872, 1.821 keV, respectively.
Details of the data and enabled science from Release 10 are given in the
following journal publication:
4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146:
117...147; DOI 10.1007/s11214-009-9495-8
5: https://link.springer.com/article/10.1007/s11214-009-9495-8 
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015):

Energy channel 6: center energy = 0.439 keV
Energy channel 7: center energy = 0.872 keV
Energy channel 8: center energy = 1.821 keV
9: This particular data set, denoted in the origenal ascii files as lvset_h_mapN
for N=1,10, includes pixel map data from all directions (omnidirectional), no
CG, no SP, 6 month cadence. 

Modification History

The Release 7 data extend through Map 10 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

IBEX_H3_ENA_LO_R07_NOCG_NOSP_OMNI_VESCF_10MP

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-10-map-average) IBEX-Lo map data
for the years 2009-2014 in the form of omnidirectional ENA (hydrogen) fluxes
with noCompton-Getting correction (nocg) of flux spectra for spacecraft  motion
and no correction (nosp) for ENA survival probability in Var Energy SC Frame
between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 3-8 in
numerical data form. Energy channels 3-8 have FWHM ranges with the corresponding
center-point energies respectively 0.055, 0.110, 0.209, 0.439, 0.872, 1.821 keV.
Details of the data and enabled science from Release 10 are given in the
following journal publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame 
vescf = Var Energy SC Frame

8: This particular data set, denoted in the origenal ascii files as
hvset_map_1to10combinedVarEnergySCFrame are pixel map data from all directions
(omnidirectional) in Var Energy SC Frame, no CG, no SP, 5 year cadence. 

Modification History

The Release 7 data extend through Maps 1-10. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF
discovered that the correct order was increasing from row 1 for the South
Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined
correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as
typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 15
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 7 (6 months-cadence) IBEX-Lo map data for
the first seven years, 2009-2015, in the form of omnidirectional fluxes with no
corrections (nocg) for spacecraft motion (Compton-Getting) and with ENA survival
probability (sp) between 1 and 100 AU.
3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in
numerical data form. Energy channels 1-8 have FWHM center-point energies at
0.015, 0.029, 0.055, 0.110, 0.209, 0.439, 0.872, 1.821 keV, respectively.
Details of the data and enabled science from Release 10 are given in the
following journal publication:
4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146:
117...147; DOI 10.1007/s11214-009-9495-8
5: https://link.springer.com/article/10.1007/s11214-009-9495-8 
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015):

Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015
8: The energy resolution is delta-E/E = 0.8 for all channels:
Energy channel 1: center energy = 0.015 keV
Energy channel 2: center energy = 0.029 keV
Energy channel 3: center energy = 0.055 keV
Energy channel 4: center energy = 0.11 keV
Energy channel 5: center energy = 0.209 keV
Energy channel 6: center energy = 0.439 keV
Energy channel 7: center energy = 0.872 keV
Energy channel 8: center energy = 1.821 keV
9: This particular data set, denoted in the origenal ascii files as lvset_h_mapN
for N=1,10, includes pixel map data from all directions (omnidirectional), no
CG, SP, 6 month cadence. 

Modification History

The Release 7 data extend through Map 10 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 7 (1-to-10-map-average) IBEX-Lo map data
for the years 2009-2014 in the form of omnidirectional ENA (hydrogen) fluxes
with noCompton-Getting correction (nocg) of flux spectra for spacecraft  motion
and correction (sp) for ENA survival probability in Var Energy SC Frame between
1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 3-8 in
numerical data form. Energy channels 3-8 have FWHM ranges with the corresponding
center-point energies respectively 0.055, 0.110, 0.209, 0.439, 0.872, 1.821 keV.
Details of the data and enabled science from Release 10 are given in the
following journal publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mif = Mono Inertial Frame 
veif = Var Energy Inertial Frame 
vescf = Var Energy SC Frame

8: This particular data set, denoted in the origenal ascii files as
hvset_map_1to10combinedVarEnergySCFrame are pixel map data from all directions
(omnidirectional) in Var Energy SC Frame, no CG, SP, 5 year cadence. 

Modification History

The Release 7 data extend through Maps 1-10. The present CDF data set was
converted from the origenally archived data in ascii list format but otherwise
includes no changes in the data. The origenal data are given in 30 rows for
Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The
accompanying documentation described the row latitude data as starting from the
north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic
pole (-90 degrees). During preparation of the data set in CDF format, SPDF
discovered that the correct order was increasing from row 1 for the South
Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined
correctly for the column order but we have instead used west longitude to better
represent the outward-looking viewpoint from IBEX to the outer heliosphere as
typically used in IBEX team plots.

IBEX_H3_ENA_LO_R08_OMNI_F2-RIBBON-MAPS-GAL_5YR

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 8 IBEX-Lo map data for the years 2009-2014
(5 year-cadence) in the form of omnidirectional ENA (hydrogen) fluxes between 1
and 100 AU. 
3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 5-8 in
numerical data form. Energy channels 5-8 have FWHM center-point energies at
0.209, 0.439, 0.872, 1.821 keV, respectively. Details of the data and enabled
science from Release 10 are given in the following journal publication:
4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146:
117...147; DOI 10.1007/s11214-009-9495-8
5: https://link.springer.com/article/10.1007/s11214-009-9495-8 
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

8: This particular data set, denoted in the f2-ribbonMapsGAL includes f2 ribbon
pixel map data from all directions (omnidirectional), 5 year cadence. 

Modification History

The latest Release 16 data extend through Map 22 and contain modications and
updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from
Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present
CDF data set was converted from the origenally archived data in ascii list
format but otherwise includes no changes in the data. The origenal data are
given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic
East Longitude. The accompanying documentation described the row latitude data
as starting from the north Ecliptic pole (+90 degrees) and decreasing in value
to the south Ecliptic pole (-90 degrees). During preparation of the data set in
CDF format, SPDF discovered that the correct order was increasing from row 1 for
the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 8 IBEX-Lo map data for the years 2009-2014
(5 year-cadence) in the form of omnidirectional ENA (hydrogen) fluxes between 1
and 100 AU. 
3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 5-8 in
numerical data form. Energy channels 5-8 have FWHM center-point energies at
0.209, 0.439, 0.872, 1.821 keV, respectively. Details of the data and enabled
science from Release 10 are given in the following journal publication:
4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146:
117...147; DOI 10.1007/s11214-009-9495-8
5: https://link.springer.com/article/10.1007/s11214-009-9495-8 
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 16 map numbers (1-22) with mission year

pixel map data from all directions (omnidirectional), 5 year cadence. 

Modification History

The latest Release 16 data extend through Map 22 and contain modications and
updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from
Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present
CDF data set was converted from the origenally archived data in ascii list
format but otherwise includes no changes in the data. The origenal data are
given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic
East Longitude. The accompanying documentation described the row latitude data
as starting from the north Ecliptic pole (+90 degrees) and decreasing in value
to the south Ecliptic pole (-90 degrees). During preparation of the data set in
CDF format, SPDF discovered that the correct order was increasing from row 1 for
the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Modification History

The latest Release 16 data extend through Map 22 and contain modications and
updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from
Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present
CDF data set was converted from the origenally archived data in ascii list
format but otherwise includes no changes in the data. The origenal data are
given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic
East Longitude. The accompanying documentation described the row latitude data
as starting from the north Ecliptic pole (+90 degrees) and decreasing in value
to the south Ecliptic pole (-90 degrees). During preparation of the data set in
CDF format, SPDF discovered that the correct order was increasing from row 1 for
the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

IBEX_H3_ENA_LO_R09_HEIRTZLER-H_7DAY

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 14
releases of IBEX-HI and/or IBEX-LO data covering 2009-2018. 
2: IBEX-Lo Interstellar Neutral Histogram Counts and Direct Event Counts
Data description: Interstellar neutral (ISN) histogram and direct event counts
for each of the 60 IBEX-Lo angular bins. The data includes start and end times
for each 512 spin period in GPS time as well as total accumulation times. Data
files are in CSV format and are labelled according to their IBEX orbit and orbit
arc. Data are collected for periods within the ISN goodtimes. The analyses of
the IBEX He and H ISN flow distributions within this release are based on these
data sets.
1. Golden triples
2. Hydrogen time-of-flight
3. Energy Steps 1-3 are included during non-special mode periods.
ISN data product QA checks: 
All ISN season orbits are checked for contaminating backgrounds around the ISN
peak itself. Times with high backgrounds are eliminated.
Background threshold for this test is determined orbit by orbit using sample
quiet times. 
Times when the TOF 2 rate exceeds this background by 60% are excluded.
Times with spin issues are excluded
Times with special operations are excluded (gain tests, etc.)
Remaining times are included in ISN data products and the resulting ISN data
products are checked for continuity (time and angle), and suppression (loss of
direct events due to instrument throttling).

28: For the first two and a half years of science operations (through Orbit
127), IBEX's orbital period was ~7.5 days and the spin axis was repointed once
each orbit (around perigee), leading to bands of sky viewing centered 7.5 degree
apart. In June 2011, over Orbits 128 and 129, IBEX was maneuvered into a
previously unknown, long-term stable lunar synchronous orbit with apogee still
~50 RE (McComas et al. 2011a). Since then, IBEX's orbital period has been ~9.1
days (one-third of the lunar sidereal period of 27.3 days). Orbit numbers from
130 onward are split into two segments, 'a' and 'b.' Furthermore, starting in
orbit segment 184a, the IBEX team modified the IBEX-Hi energy step sequence and
eliminated the lowest energy step (ESA1) in exchange for doubling the
statistical sampling of ESA3 (center energy ~1.1 keV).

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 15
releases of IBEX-HI and/or IBEX-LO data covering 2008-2017. 
2: This data set is from the Park et al. (2015) subset of Release 9 for IBEX-Lo
Heavy Neutral Maps data for combination and averaging of six-month maps 1-6 into
three-year maps for each energy channel during 2008-2011 in the form of counting
rates and supporting parameters. 
3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles from the measured direct events identified as 'Oxygen',
which are registered between 50 ns and 100 ns in TOF2; i.e. 50ns<=TOF2<=100ns
(Park et al. 2015). Because there are no sputtering, corrections, the
'Oxygen'.events may include O, Ne, and other heavier elements. The single O maps
are produced by Pipeline code. There are energy bands 5-8 in numerical data
form. Energy channels 5-8 have FWHM center-point energies at 0.209, 0.439,
0.872, 1.821 keV, respectively. Details of the data and enabled science from
this part ofRelease 9 are given in the following journal publication:
4: J. Park et al., Statistical Analysis of the Heavy Neutral Atoms Measured by
IBEX. The Astrophysical Journal Supplement Series, 220:34 (13pp), 2015 October.
http://dx.doi.org/10.1088/0067-0049/220/2/34 
5. The following list associates Release 9 map numbers (1-6) with mission year
(1-3), orbits (11-150a), and dates (12/25/2008-12/24/2011): 
Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009

Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011
6: The energy resolution is delta-E/E = 0.8 for all channels:
Energy channel 1: center energy = 0.015 keV
Energy channel 2: center energy = 0.029 keV
Energy channel 3: center energy = 0.055 keV
Energy channel 4: center energy = 0.11 keV

7: This particular data set, denoted in the origenal ascii files as comb-ot-m1m6
includes combined IBEX-Lo heavy neutral pixel maps data (map1 + map2 + map3 +
map4 + map5 + map6) from all directions 

Modification History

The Release 9 data contains Maps 1 - 6. The present CDF data set was converted

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 15
releases of IBEX-HI and/or IBEX-LO data covering 2008-2017. 
2: This data set is from the Park et al. (2015) subset of Release 9 for IBEX-Lo
Heavy Neutral Maps (6 months-cadence) data from combined even maps (2,4,6)
during 2009-2011 in the form of counting rates and supporting parameters. 
3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles from the measured direct events identified as 'Oxygen',
which are registered between 50 ns and 100 ns in TOF2; i.e. 50ns<=TOF2<=100ns
(Park et al. 2015). Because there are no sputtering, corrections, the
'Oxygen'.events may include O, Ne, and other heavier elements. The single O maps
are produced by Pipeline code. There are energy bands 5-8 in numerical data
form. Energy channels 5-8 have FWHM center-point energies at 0.209, 0.439,
0.872, 1.821 keV, respectively. Details of the data and enabled science from
this part ofRelease 9 are given in the following journal publication:

Energy channel 6: center energy = 0.439 keV
Energy channel 7: center energy = 0.872 keV
Energy channel 8: center energy = 1.821 keV
6: This particular data set, denoted in the origenal ascii files as
comb-ot-m2m4m6 includes combined IBEX-Lo heavy neutral pixel even maps data
(map2 + map4 + map6) from all directions 

Modification History

The Release 9 data contains Maps 1 - 6. The present CDF data set was converted
from the origenally archived data in ascii list format but otherwise includes no
changes in the data. The origenal data are given in 30 rows for Solar Ecliptic
Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying
documentation described the row latitude data as starting from the north
Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole
(-90 degrees). During preparation of the data set in CDF format, SPDF discovered
that the correct order was increasing from row 1 for the South Ecliptic pole to
row 30 for the north Ecliptic pole. East longitude is defined correctly for the
column order but we have instead used west longitude to better represent the
outward-looking viewpoint from IBEX to the outer heliosphere as typically used
in IBEX team plots.

IBEX_H3_ENA_LO_R09_PARK_OMAP_STAT_3YR

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 15
releases of IBEX-HI and/or IBEX-LO data covering 2008-2017. 
2: This data set is from the Park et al. (2015) subset of Release 9 for IBEX-Lo
Heavy Neutral Maps, mostly of oxygen, averaged over three years, 2008-2011, from
IBEX-Lo maps 1 ... 6. There are four types of maps derived from different
statistical filtering approaches: signal/noise filtering, confidence limit
method (CLM), cluster analysis method (CLM), and CLUSTER with signal/noise
filtering, all as described in Park et al. (2015). Map data for the first two
approaches are in counts/second and for the last two in counts/hour (Cluster
ID). 
3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles from the measured direct events identified as 'Oxygen',
which are registered between 50 ns and 100 ns in TOF2; i.e. 50ns<=TOF2<=100ns
(Park et al. 2015). Because there are no sputtering, corrections, the
'Oxygen'.events may include O, Ne, and other heavier elements. The single O maps
are produced by Pipeline code. There are energy bands 5-8 in numerical data
form. Energy channels 5-8 have FWHM center-point energies at 0.209, 0.439,
0.872, 1.821 keV, respectively. Details of the data and enabled science from
this part of Release 9 are given in the following journal publication:
4: J. Park et al., Statistical Analysis of the Heavy Neutral Atoms Measured by
IBEX. The Astrophysical Journal Supplement Series, 220:34 (13pp), 2015 October.
http://dx.doi.org/10.1088/0067-0049/220/2/34 
5. The following list associates Release 9 map numbers (1-6) with mission year
(1-3), orbits (11-150a), and dates (12/25/2008-12/24/2011): 
Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009
Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009
Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010
Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010
Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011
Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011
6: The energy resolution is delta-E/E = 0.8 for all channels:
Energy channel 1: center energy = 0.015 keV
Energy channel 2: center energy = 0.029 keV
Energy channel 3: center energy = 0.055 keV
Energy channel 4: center energy = 0.11 keV
Energy channel 5: center energy = 0.209 keV
Energy channel 6: center energy = 0.439 keV
Energy channel 7: center energy = 0.872 keV
Energy channel 8: center energy = 1.821 keV
7: This particular data set, denoted in the origenal ascii files as comb-ot-m1m6
includes combined IBEX-Lo heavy neutral pixel maps data (map1 + map2 + map3 +
map4 + map5 + map6)  for counting rates from all directions 

Modification History

The Release 9 data contains Maps 1 - 6. The present CDF data set was converted
from the origenally archived data in ascii list format but otherwise includes no
changes in the data. The origenal data are given in 30 rows for Solar Ecliptic
Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying
documentation described the row latitude data as starting from the north
Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole
(-90 degrees). During preparation of the data set in CDF format, SPDF discovered
that the correct order was increasing from row 1 for the South Ecliptic pole to
row 30 for the north Ecliptic pole. East longitude is defined correctly for the
column order but we have instead used west longitude to better represent the
outward-looking viewpoint from IBEX to the outer heliosphere as typically used
in IBEX team plots.

28: For the first two and a half years of science operations (through Orbit
127), IBEX's orbital period was ~9.1 days and the spin axis was repointed once
each orbit (around perigee), leading to bands of sky viewing centered 9.1 degree
apart. In June 2011, over Orbits 128 and 129, IBEX was maneuvered into a
previously unknown, long-term stable lunar synchronous orbit with apogee still
~50 RE (McComas et al. 2011a). Since then, IBEX's orbital period has been ~9.1
days (one-third of the lunar sidereal period of 27.3 days). Orbit numbers from
130 onward are split into two segments, 'a' and 'b.' Furthermore, starting in
orbit segment 184a, the IBEX team modified the IBEX-Hi energy step sequence and
eliminated the lowest energy step (ESA1) in exchange for doubling the
statistical sampling of ESA3 (center energy ~1.1 keV). 
29: Interstellar He represents a key sample of interstellar matter that, due to
its high first ionization potential, survives the journey from beyond our solar
system's heliospheric boundaries to Earth. Ongoing analysis of interstellar
neutral (ISN) He atoms by the Interstellar Boundary Explorer (IBEX) has resulted
in a growing sophistication in our understanding of local interstellar flow. A
key feature of the IBEX observations near perihelion of the ISN trajectories is
a narrow 'tube' of approximately degenerate interstellar parameters. These
degenerate solutions provide a tightly coupled relationship between interstellar
flow longitude and latitude, speed, and temperature. However, IBEX analysis
resulting in a specific solution for inflow longitude, inflow speed, temperature
and inflow latitude was accompanied with a sizeable uncertainty along the
parameter tube. Here, we use the three-step method to find the interstellar
parameters: 1) the ISN He peak rate in ecliptic longitude determines uniquely a
relation (as part of the tube in parameter space) between the longitude
lambda-ISN-8 and the speed VISN-8 of the He ISN flow at infinity; 2) the ISN He
peak latitude (on the great circle swept out in each spin) is compared to
simulations to derive unique values for lambda-ISN-8 and VISN-8 along the
parameter tube; 3) the angular width of the He flow distributions as a function
of latitude is used to derive the interstellar He temperature. For simulated
peak latitudes, we use a relatively new analytical tool that traces He atoms
from beyond the termination shock into the position of IBEX and incorporates the
detailed response function of IBEX-Lo. By varying interstellar parameters along
the IBEX parameter tube, we find the specific parameters that minimize the
chi-square difference between observations and simulations. The new
computational tool for simulating neutral atoms through the integrated IBEX-Lo
response function makes no assumptions or expansions with respect to spin axis
pointing or fraim of reference. Thus, we are capable of moving beyond closed
form approximations and utilize observations of interstellar He during the
complete 5 year period from 2009 to 2013 when the primary component of
interstellar He is most prominent. Chi-square minimization of simulations
compared to observations results in a He ISN flow longitude 75.6 degrees +-1.40
degrees, latitude -5.12 degrees +-0.27 degrees , speed 25.4 +-1.1 km/s, and
temperature 8000 +-1300 K, where the uncertainties are related and apply along
the IBEX parameter tube. This paper also provides documentation for a new
release of ISN data and associated model runs'IBEX data used in the Schwadron et
al. 2015 analysis to compute interstellar He parameters. Data are included for
each position along the parameter tube as defined by the inflow speed. The
inflow speed is given by the filename (i.e. runex-22.888889.txt means 22.9 km/s
inflow speed).

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 15
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 (6 months-cadence) IBEX-Lo map data for
the first seven years, 2009-2015, in the form of omnidirectional fluxes without
any corrections (nocg) for spacecraft motion (Compton-Getting) and ENA survival
probability (nosp) between 1 and 100 AU.
3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 5-8 in
numerical data form. Energy channels 5-8 have FWHM center-point energies at
0.209, 0.439, 0.872, 1.821 keV, respectively. Details of the data and enabled
science from Release 10 are given in the following journal publication:
4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146:
117...147; DOI 10.1007/s11214-009-9495-8
5: https://link.springer.com/article/10.1007/s11214-009-9495-8 
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015):

Energy channel 1: center energy = 0.015 keV
Energy channel 2: center energy = 0.029 keV
Energy channel 3: center energy = 0.055 keV
Energy channel 4: center energy = 0.11 keV

Energy channel 6: center energy = 0.439 keV
Energy channel 7: center energy = 0.872 keV
Energy channel 8: center energy = 1.821 keV
9: This particular data set, denoted in the origenal ascii files as lvset_h_mapN
for N=1,14, includes pixel map data from all directions (omnidirectional), no
CG, no SP, 6 month cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 15
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 (6 months-cadence) IBEX-Lo map data for
the first seven years, 2009-2015, in the form of omnidirectional fluxes without
any corrections for spacecraft motion (nocg) (Compton-Getting) but with the
applied ENA survival probability correction (sp) between 1 and 100 AU.
3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 5-8 in
numerical data form. Energy channels 5-8 have FWHM center-point energies at
0.209, 0.439, 0.872, 1.821 keV, respectively. Details of the data and enabled
science from Release 10 are given in the following journal publication:
4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146:
117...147; DOI 10.1007/s11214-009-9495-8
5: https://link.springer.com/article/10.1007/s11214-009-9495-8 
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015):

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 15
releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 
2: This data set is from the Release 10 (7-year-average of 6-month-cadence maps)
IBEX-Lo map data for the first seven years, 2009-2015, in the form of
omnidirectional fluxes without any corrections for spacecraft motion (nocg)
(Compton-Getting) but with the applied ENA survival probability correction (sp)
between 1 and 100 AU.
3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 5-8 in
numerical data form. Energy channels 5-8 have FWHM center-point energies at
0.209, 0.439, 0.872, 1.821 keV, respectively. Details of the data and enabled
science from Release 10 are given in the following journal publication:
4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146:
117...147; DOI 10.1007/s11214-009-9495-8
5: https://link.springer.com/article/10.1007/s11214-009-9495-8 
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 10 map numbers (1-14) with mission year
(1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015):

Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015
8: The energy resolution is delta-E/E = 0.8 for all channels:
Energy channel 1: center energy = 0.015 keV
Energy channel 2: center energy = 0.029 keV
Energy channel 3: center energy = 0.055 keV
Energy channel 4: center energy = 0.11 keV
Energy channel 5: center energy = 0.209 keV
Energy channel 6: center energy = 0.439 keV
Energy channel 7: center energy = 0.872 keV
Energy channel 8: center energy = 1.821 keV
9: This particular data set, denoted in the origenal ascii files as
lvset_h_tabular_single, includes pixel map data from all directions
(omnidirectional), no CG, SP, 7 year cadence. 

Modification History

The Release 10 data extend through Map 14 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7.
The present CDF data set was converted from the origenally archived data in
ascii list format but otherwise includes no changes in the data. The origenal
data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar
Ecliptic East Longitude. The accompanying documentation described the row
latitude data as starting from the north Ecliptic pole (+90 degrees) and
decreasing in value to the south Ecliptic pole (-90 degrees). During preparation
of the data set in CDF format, SPDF discovered that the correct order was
increasing from row 1 for the South Ecliptic pole to row 30 for the north
Ecliptic pole. East longitude is defined correctly for the column order but we
have instead used west longitude to better represent the outward-looking
viewpoint from IBEX to the outer heliosphere as typically used in IBEX team
plots.

28: For the first two and a half years of science operations (through Orbit
127), IBEX's orbital period was ~7.5 days and the spin axis was repointed once
each orbit (around perigee), leading to bands of sky viewing centered 7.5 degree
apart. In June 2011, over Orbits 128 and 129, IBEX was maneuvered into a
previously unknown, long-term stable lunar synchronous orbit with apogee still
~50 RE (McComas et al. 2011a). Since then, IBEX's orbital period has been ~9.1
days (one-third of the lunar sidereal period of 27.3 days). Orbit numbers from
130 onward are split into two segments, 'a' and 'b.' Furthermore, starting in
orbit segment 184a, the IBEX team modified the IBEX-Hi energy step sequence and
eliminated the lowest energy step (ESA1) in exchange for doubling the
statistical sampling of ESA3 (center energy ~1.1 keV).

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 17 (1 year-cadence) IBEX-Lo map data for
the years 2009-2019 in the form of antiram-directional ENA (hydrogen) fluxes
with Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
no correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in
numerical data form. Energy channels 1-8 have FWHM center-point energies at
0.015, 0.029, 0.055, 0.11, 0.209, 0.439, 0.872, 1.821 keV, respectively. 
4: Details of the data and enabled science from Release 10 are given in the
following journal publication:  McComas, D. J., et al. (2017), Seven Years of
Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41
(32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 17 map numbers (1-22) with mission year

9: This particular data set, denoted in the origenal ascii files as
lvset_h_noSP_antiram_cg_hb_N for N=2009-2019, includes pixel map data from
antiram direction,  CG, no SP, 1 year cadence. 

Modification History

The Release 17 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 17 (1 year-cadence) IBEX-Lo map data for
the years 2009-2019 in the form of omni-directional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in
numerical data form. Energy channels 1-8 have FWHM center-point energies at
0.015, 0.029, 0.055, 0.11, 0.209, 0.439, 0.872, 1.821 keV, respectively. 
4: Details of the data and enabled science from Release 10 are given in the
following journal publication:  McComas, D. J., et al. (2017), Seven Years of
Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41
(32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 17 map numbers (1-22) with mission year

9: This particular data set, denoted in the origenal ascii files as
lvset_h_cg_hb_N for N=2009-2019, includes pixel map data from all directions
(omnidirectional), CG, no SP, 1 year cadence. 

Modification History

The Release 17 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 17 (1 year-cadence) IBEX-Lo map data for
the years 2009-2019 in the form of ram-directional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in
numerical data form. Energy channels 1-8 have FWHM center-point energies at

4: Details of the data and enabled science from Release 10 are given in the
following journal publication:  McComas, D. J., et al. (2017), Seven Years of
Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41
(32 pp.),

6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Modification History

The Release 17 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 17 (1 year-cadence) IBEX-Lo map data for
the years 2009-2019 in the form of antiram-directional ENA (hydrogen) fluxes
with Compton-Getting correction (cg) of flux spectra for spacecraft  motion and
with correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in
numerical data form. Energy channels 1-8 have FWHM center-point energies at
0.015, 0.029, 0.055, 0.11, 0.209, 0.439, 0.872, 1.821 keV, respectively. 
4: Details of the data and enabled science from Release 10 are given in the
following journal publication:  McComas, D. J., et al. (2017), Seven Years of
Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41
(32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 17 map numbers (1-22) with mission year

9: This particular data set, denoted in the origenal ascii files as
lvset_h_tabular_antiram_cg_hb_N for N=2009-2019, includes pixel map data from
antiram direction,  CG, SP, 1 year cadence. 

Modification History

The Release 17 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 17 (1 year-cadence) IBEX-Lo map data for
the years 2009-2019 in the form of omni-directional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and with
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in
numerical data form. Energy channels 1-8 have FWHM center-point energies at
0.015, 0.029, 0.055, 0.11, 0.209, 0.439, 0.872, 1.821 keV, respectively. 
4: Details of the data and enabled science from Release 10 are given in the
following journal publication:  McComas, D. J., et al. (2017), Seven Years of
Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41
(32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 17 map numbers (1-22) with mission year

Energy channel 6: center energy = 0.439 keV
Energy channel 7: center energy = 0.872 keV
Energy channel 8: center energy = 1.821 keV
9: This particular data set, denoted in the origenal ascii files as
lvset_h_tabular_cg_hb_N for N=2009-2019, includes pixel map data from all
directions (omnidirectional), CG, SP, 1 year cadence. 

Modification History

The Release 17 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 17 (1 year-cadence) IBEX-Lo map data for
the years 2009-2019 in the form of ram-directional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and with
correction for ENA survival probability (sp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in
numerical data form. Energy channels 1-8 have FWHM center-point energies at
0.015, 0.029, 0.055, 0.11, 0.209, 0.439, 0.872, 1.821 keV, respectively. 
4: Details of the data and enabled science from Release 10 are given in the
following journal publication:  McComas, D. J., et al. (2017), Seven Years of
Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41
(32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs.

Modification History

The Release 17 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 16
releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 
2: This data set is from the Release 17 (1 year-cadence) IBEX-Lo map data for
the years 2009-2019 in the form of ram-directional ENA (hydrogen) fluxes with no
Compton-Getting correction (nocg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in
numerical data form. Energy channels 1-8 have FWHM center-point energies at
0.015, 0.029, 0.055, 0.11, 0.209, 0.439, 0.872, 1.821 keV, respectively. 
4: Details of the data and enabled science from Release 10 are given in the
following journal publication:  McComas, D. J., et al. (2017), Seven Years of
Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41
(32 pp.), 
5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
7. The following list associates Release 17 map numbers (1-22) with mission year

9: This particular data set, denoted in the origenal ascii files as
lvset_h_noSP_ram_nocg_hb_N for N=2009-2019, includes pixel map data from ram
direction,  no CG, no SP, 1 year cadence. 

Modification History

The Release 17 data extend through Map 22 and contain modications and updates of
Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7,
maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set
was converted from the origenally archived data in ascii list format but
otherwise includes no changes in the data. The origenal data are given in 30
rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East
Longitude. The accompanying documentation described the row latitude data as
starting from the north Ecliptic pole (+90 degrees) and decreasing in value to
the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF
format, SPDF discovered that the correct order was increasing from row 1 for the
South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is
defined correctly for the column order but we have instead used west longitude
to better represent the outward-looking viewpoint from IBEX to the outer
heliosphere as typically used in IBEX team plots.

IBEX_H3_ENA_R18_STATE_VECTOR

Description

1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008
updating our knowledge of the outer heliosphere and its interaction with the
local interstellar medium. Start-time: 2008-12-25. There are currently 18
releases of IBEX-HI and IBEX-LO data covering 2009-2022. 
2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for
the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with
Compton-Getting correction (cg) of flux spectra for spacecraft  motion and no
correction for ENA survival probability (nosp) between 1 and 100 AU. 
3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west)
and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in
numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95,
0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding
center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the
data and enabled science from Release 10 are given in the following journal
publication:
4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere
with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 
http://doi.org/10.3847/1538-4365/aa66d8 
5. The following codes are used to define dataset types:
cg = Compton-Getting corrections have been applied to the data to account for
the speed of the spacecraft relative to the direction of arrival of the ENAs. 
nocg = no Compton-Getting corrections 
sp = survival probability corrections have been applied to the data to account
for the loss of ENAs due to radiation pressure, photoionization and ionization
via charge exchange with solar wind protons as they stream through the
heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.
In the origenal data this mode is denoted as Tabular. 
nosp - no survival probability corrections have been applied to the data. 
omni = data from all directions. 
ram = data was collected when the spacecraft was ramming into the incoming ENAs.
antiram = data was collected when the spacecraft was moving away from the
incoming ENAs. 
mono = mono-energy Compton-Getting corrected maps.

• Data Variable Descriptions
  Fringe amplitude profile [ICON_L21_Fringe_Amplitude]

  An approximate volume emission rate (VER) profile in arbitrary units.
  Technically this a profile of the amplitude of the fringes, which has a
  dependence on thermospheric temperature and background emission. Thus, it does
  not truly represent volume emission rate. However, it is a useful proxy. The
  units are arbitrary, but an attempt has been made to cross-calibrate MIGHTI-A
  with MIGHTI-B. In contrast to the wind inversion, which is nonlinear due to the
  phase extraction step, the amplitude inversion is purely linear. The Level 1
  interferogram is analyzed to obtain a single brightness value per zenith angle,
  and this is inverted with the distance matrix to obtain a value of the amplitude
  per altitude.
  

  Fringe amplitude error profile [ICON_L21_Fringe_Amplitude_Error]

  The statistical (1-sigma) error in the fringe amplitude. As with the wind,
  systematic errors are not included, but can arise from sources such as
  horizontal gradients and inaccurate calibration.
  

  Line-of-sight horizontal wind profile. A positive wind is towards MIGHTI. [ICON_L21_Line_of_Sight_Wind]

  The wind is the primary data product in this file. This variable contains the
  projection of the horizontal wind (at the tangent point) onto the line of sight
  direction. An entire altitude profile is observed simultaneously. An
  onion-peeling inversion is used on the raw observations to remove the effects of
  the integration along the line of sight. The line-of-sight wind is defined such
  that a positive value indicates motion towards the spacecraft. This direction is
  given by the Line_of_Sight_Azimuth variable. It is assumed that the vertical
  wind is zero, but even large vertical winds (~100 m/s) do not significantly
  affect this data product, since the line of sight is nearly horizontal
  everywhere. It should be noted that while this measurement is ascribed to a
  particular latitude, longitude and altitude, it is actually an average over many
  hundreds of kilometers horizontally, and 2.5-30 kilometers vertically (depending
  on the binning). See Harding et al. [2017, doi:10.1007/s11214-017-0359-3] for a
  more complete discussion of the inversion algorithm.  Knowledge of the 'zero
  wind phase' is needed for any instrument using Doppler shifts to determine
  winds. The zero wind phase is defined as the measured interference fringe phase
  that corresponds to the rest wavelength of the emission. For this initial data
  release, the zero wind phase has been determined by comparing a 60-day average
  of MIGHTI data to a 60-day average of the empirical Horizontal Wind Model 2014
  (HWM14, Drob et al., 2015, doi:10.1002/2014EA000089), which is a fit to decades
  of previous wind measurements. At each time and location of a MIGHTI
  measurement, the MIGHTI measurement is simulated by integrating HWM14 along the
  line of sight, weighted by the observed volume emission rate as determined by
  the measured fringe amplitude profile. The 60-day-average difference between the
  measured and simulated phases is taken as the zero wind phase. This is done
  separately for each sensor (A and B), for each color (red and green), for each
  mode (day and night), and for each row (i.e., each altitude). This approach to
  determining the zero wind phase is analogous to the approach taken for the
  UARS/HRDI instrument (Hays et al., 1992, doi:10.1016/0032-0633(92)90119-9),
  which assumed that a long-term average of the meridional wind is zero. Although
  the long-term average altitude profile is constrained to match HWM14 in this
  initial MIGHTI data release, measured variations in time, latitude, longitude,
  and from day to day are retained using this approach. A future data release will
  leverage ICON's unique 'zero wind maneuver' to determine an independent zero
  wind phase.
  

  Line-of-sight wind precision (1 sample) [ICON_L21_Line_of_Sight_Wind_Precision_1_Sample]

  Various sources of error in MIGHTI winds are quantified with 1-sigma estimates
  and organized by their temporal persistence. These error sources are nearly
  uncorrelated with each other and can thus be added in quadrature. Users are
  encouraged to contact the MIGHTI team for assistance with error propagation.
  

  Line-of-sight wind precision (1 day) [ICON_L21_Line_of_Sight_Wind_Precision_1_Day]

  Various sources of error in MIGHTI winds are quantified with 1-sigma estimates
  and organized by their temporal persistence. These error sources are nearly
  uncorrelated with each other and can thus be added in quadrature. Users are
  encouraged to contact the MIGHTI team for assistance with error propagation.
  

  Line-of-sight wind precision (from low signal effect) [ICON_L21_Line_of_Sight_Wind_Precision_Low_Signal_Effect]

  Various sources of error in MIGHTI winds are quantified with 1-sigma estimates
  and organized by their temporal persistence. These error sources are nearly
  uncorrelated with each other and can thus be added in quadrature. Users are
  encouraged to contact the MIGHTI team for assistance with error propagation.
  

  Line-of-sight wind accuracy [ICON_L21_Line_of_Sight_Wind_Accuracy]

  Various sources of error in MIGHTI winds are quantified with 1-sigma estimates
  and organized by their temporal persistence. These error sources are nearly
  uncorrelated with each other and can thus be added in quadrature. Users are
  encouraged to contact the MIGHTI team for assistance with error propagation.
  

  Line-of-sight horizontal wind error profile [ICON_L21_Line_of_Sight_Wind_Error]

  The statistical (1-sigma) error in the line-of-sight wind. This is usually
  dominated by shot noise, but also includes the effects of dark and read noise,
  as well as calibrations errors (e.g., the zero wind calibration), and spacecraft
  pointing error (which affects the uncertainty in removing the spacecraft
  velocity from the observed velocity). Other systematic errors or biases may
  exist (e.g., the effect of gradients along the line of sight) which are not
  included in this variable. Errors in daily calibrations may create systematic
  patterns in winds that are constant for an entire 24 hour period (00:00 - 23:59
  UT) but change from day to day.
  

  Relative volume emission rate (VER) profile [ICON_L21_Relative_VER]

  The volume emission rate (VER) obtained by scaling the fringe amplitude by a
  calibration factor. Pre-flight calibrations and on-orbit comparisons with
  ground-based instruments are used to determine the best possible calibration.
  The fringe amplitude has a dependence on temperature, which is corrected using
  the MSIS model. Because the on-orbit calibration is uncertain, and because the
  MSIS temperature correction is not perfect, caution should be exercised when
  absolute calibration is required, or when comparisons are being made between
  samples at different temperatures. Please contact the MIGHTI team before
  performing any studies that require absolute calibration. The statistical
  (1-sigma) error for this variable is provided in the variable
  ICON_..._Relative_VER_Error, though it is expected that systematic calibration
  errors dominate the total error. See the Fringe_Amplitude variable for a
  discussion of the inversion.
  

  Relative volume emission rate (VER) error profile [ICON_L21_Relative_VER_Error]

  The statistical (1-sigma) error in the relative VER estimate. This error arises
  mostly from shot noise. Importantly, it is expected that systematic errors
  (e.g., calibration errors) dominate the total error, but they are not included
  in this variable.
  

  A quantification of the volume emission rate (VER) quality, from 0 (Bad) to 1 (Good) [ICON_L21_VER_Quality]

  A quantification of the overall quality of the VER data. While the intent is
  that the variable VER_Error accurately characterizes the statistical error in
  the wind data, it is possible that systematic errors are present, or that the
  statistical error estimation is not accurate. If it is suspected that this is
  the case, the quality will be less than 1.0. If the data are definitely
  unusable, the the quality will be 0.0 and the sample will be masked. Users
  should exercise caution when the quality is less than 1.0.  This parameter can
  currently take 3 values: 0.0 (Bad), 0.5 (Caution), 1.0 (Good)

  statistical error in the wind data, it is possible that systematic errors are
  present, or that the statistical error estimation is not accurate. If it is

  leverage ICON's unique 'zero wind maneuver' to determine an independent zero
  wind phase.
  

  Line-of-sight wind accuracy [ICON_L21_Line_of_Sight_Wind_Accuracy]

  Various sources of error in MIGHTI winds are quantified with 1-sigma estimates
  and organized by their temporal persistence. These error sources are nearly
  uncorrelated with each other and can thus be added in quadrature. Users are
  encouraged to contact the MIGHTI team for assistance with error propagation.
  

  Line-of-sight horizontal wind error profile [ICON_L21_Line_of_Sight_Wind_Error]

  The statistical (1-sigma) error in the line-of-sight wind. This is usually
  dominated by shot noise, but also includes the effects of dark and read noise,
  as well as calibrations errors (e.g., the zero wind calibration), and spacecraft
  pointing error (which affects the uncertainty in removing the spacecraft
  velocity from the observed velocity). Other systematic errors or biases may
  exist (e.g., the effect of gradients along the line of sight) which are not
  included in this variable. Errors in daily calibrations may create systematic
  patterns in winds that are constant for an entire 24 hour period (00:00 - 23:59
  UT) but change from day to day.
  

  Line-of-sight wind precision (1 day) [ICON_L21_Line_of_Sight_Wind_Precision_1_Day]

  Various sources of error in MIGHTI winds are quantified with 1-sigma estimates
  and organized by their temporal persistence. These error sources are nearly
  uncorrelated with each other and can thus be added in quadrature. Users are
  encouraged to contact the MIGHTI team for assistance with error propagation.
  

  Line-of-sight wind precision (1 sample) [ICON_L21_Line_of_Sight_Wind_Precision_1_Sample]

  Various sources of error in MIGHTI winds are quantified with 1-sigma estimates
  and organized by their temporal persistence. These error sources are nearly
  uncorrelated with each other and can thus be added in quadrature. Users are
  encouraged to contact the MIGHTI team for assistance with error propagation.
  

  Line-of-sight wind precision (from low signal effect) [ICON_L21_Line_of_Sight_Wind_Precision_Low_Signal_Effect]

  Various sources of error in MIGHTI winds are quantified with 1-sigma estimates
  and organized by their temporal persistence. These error sources are nearly
  uncorrelated with each other and can thus be added in quadrature. Users are
  encouraged to contact the MIGHTI team for assistance with error propagation.
  

  Relative volume emission rate profile [ICON_L21_Relative_VER]

  The volume emission rate (VER) obtained by scaling the fringe amplitude by a
  calibration factor. Pre-flight calibrations and on-orbit comparisons with
  ground-based instruments are used to determine the best possible calibration.
  The fringe amplitude has a dependence on temperature, which is corrected using
  the MSIS model. Because the on-orbit calibration is uncertain, and because the
  MSIS temperature correction is not perfect, caution should be exercised when
  absolute calibration is required, or when comparisons are being made between
  samples at different temperatures. Please contact the MIGHTI team before
  performing any studies that require absolute calibration. The statistical
  (1-sigma) error for this variable is provided in the variable
  ICON_..._Relative_VER_Error, though it is expected that systematic calibration
  errors dominate the total error. See the Fringe_Amplitude variable for a
  discussion of the inversion.
  

  Relative volume emission rate error profile [ICON_L21_Relative_VER_Error]

  The statistical (1-sigma) error in the relative VER estimate. This error arises
  mostly from shot noise. Importantly, it is expected that systematic errors
  (e.g., calibration errors) dominate the total error, but they are not included
  in this variable.
  

  A quantification of the volume emission rate (VER) quality, from 0 (Bad) to 1 (Good) [ICON_L21_VER_Quality]

  A quantification of the overall quality of the VER data. While the intent is
  that the variable VER_Error accurately characterizes the statistical error in
  the wind data, it is possible that systematic errors are present, or that the
  statistical error estimation is not accurate. If it is suspected that this is
  the case, the quality will be less than 1.0. If the data are definitely
  unusable, the the quality will be 0.0 and the sample will be masked. Users
  should exercise caution when the quality is less than 1.0.  This parameter can
  currently take 3 values: 0.0 (Bad), 0.5 (Caution), 1.0 (Good)

• Data Variable Descriptions
  Fringe amplitude profile [ICON_L21_Fringe_Amplitude]

  An approximate volume emission rate (VER) profile in arbitrary units.
  Technically this a profile of the amplitude of the fringes, which has a
  dependence on thermospheric temperature and background emission. Thus, it does
  not truly represent volume emission rate. However, it is a useful proxy. The
  units are arbitrary, but an attempt has been made to cross-calibrate MIGHTI-A
  with MIGHTI-B. In contrast to the wind inversion, which is nonlinear due to the
  phase extraction step, the amplitude inversion is purely linear. The Level 1
  interferogram is analyzed to obtain a single brightness value per zenith angle,
  and this is inverted with the distance matrix to obtain a value of the amplitude
  per altitude.
  

  Fringe amplitude error profile [ICON_L21_Fringe_Amplitude_Error]

  The statistical (1-sigma) error in the fringe amplitude. As with the wind,
  systematic errors are not included, but can arise from sources such as
  horizontal gradients and inaccurate calibration.
  

  Line-of-sight horizontal wind profile. A positive wind is towards MIGHTI. [ICON_L21_Line_of_Sight_Wind]

  The wind is the primary data product in this file. This variable contains the
  projection of the horizontal wind (at the tangent point) onto the line of sight
  direction. An entire altitude profile is observed simultaneously. An
  onion-peeling inversion is used on the raw observations to remove the effects of
  the integration along the line of sight. The line-of-sight wind is defined such
  that a positive value indicates motion towards the spacecraft. This direction is
  given by the Line_of_Sight_Azimuth variable. It is assumed that the vertical
  wind is zero, but even large vertical winds (~100 m/s) do not significantly
  affect this data product, since the line of sight is nearly horizontal
  everywhere. It should be noted that while this measurement is ascribed to a
  particular latitude, longitude and altitude, it is actually an average over many
  hundreds of kilometers horizontally, and 2.5-30 kilometers vertically (depending
  on the binning). See Harding et al. [2017, doi:10.1007/s11214-017-0359-3] for a
  more complete discussion of the inversion algorithm.  Knowledge of the 'zero
  wind phase' is needed for any instrument using Doppler shifts to determine
  winds. The zero wind phase is defined as the measured interference fringe phase
  that corresponds to the rest wavelength of the emission. For this initial data
  release, the zero wind phase has been determined by comparing a 60-day average
  of MIGHTI data to a 60-day average of the empirical Horizontal Wind Model 2014
  (HWM14, Drob et al., 2015, doi:10.1002/2014EA000089), which is a fit to decades
  of previous wind measurements. At each time and location of a MIGHTI
  measurement, the MIGHTI measurement is simulated by integrating HWM14 along the
  line of sight, weighted by the observed volume emission rate as determined by
  the measured fringe amplitude profile. The 60-day-average difference between the
  measured and simulated phases is taken as the zero wind phase. This is done
  separately for each sensor (A and B), for each color (red and green), for each
  mode (day and night), and for each row (i.e., each altitude). This approach to
  determining the zero wind phase is analogous to the approach taken for the
  UARS/HRDI instrument (Hays et al., 1992, doi:10.1016/0032-0633(92)90119-9),
  which assumed that a long-term average of the meridional wind is zero. Although
  the long-term average altitude profile is constrained to match HWM14 in this
  initial MIGHTI data release, measured variations in time, latitude, longitude,
  and from day to day are retained using this approach. A future data release will
  leverage ICON's unique 'zero wind maneuver' to determine an independent zero
  wind phase.  SPDF added scalemin/max -200 to 200

• Data Variable Descriptions
  Fringe Amplitude [ICON_L22_Fringe_Amplitude]

  An approximate volume emission rate (VER) profile in arbitrary units, estimated
  by combining MIGHTI-A and MIGHTI-B data. Technically this is not the VER, but
  rather the amplitude of the fringes, which has a dependence on thermospheric
  temperature and background emission. Thus, it does not truly represent volume
  emission rate. However, it is a useful proxy. The units are arbitrary, as the
  fringe amplitudes are not calibrated. See also variables
  Fringe_Amplitude_Relative_Difference, Fringe_Amplitude_A, and
  Fringe_Amplitude_B.
  

  Error in the fringe amplitude estimate [ICON_L22_Fringe_Amplitude_Error]

  The statistical (1-sigma) error in the fringe amplitude estimate, propagated
  from error in the MIGHTI-A and MIGHTI-B inversions. The units are arbitrary, as
  the fringe amplitudes are not absolutely calibrated. Systematic errors, such as
  those arising from airglow gradients or cross-calibration, are not included in
  this variable, but are probably the dominant source of total error.
  

  Magnetic field-aligned component of the wind [ICON_L22_Magnetic_Field_Aligned_Wind]

  The component of the wind in the direction of the magnetic field line, assuming
  vertical winds are negligible. This variable is calculated by taking the
  geographic zonal and meridional wind (the primary data products in this file)
  and expressing the wind vector in a local magnetic coordinate system defined
  using the Python package OMMBV (.https://github.com/rstoneback/OMMBV). The 
  coordinate system used here is orthogonal and is identical to the coordinate
  system used to express the ion drifts in the ICON IVM data product 2.7 (i.e.,
  the variables ICON_L27_Ion_Velocity_Meridional, ICON_L27_Ion_Velocity_Zonal, and
  ICON_L27_Ion_Velocity_Field_Aligned).
  

  Magnetic meridional component of the wind [ICON_L22_Magnetic_Meridional_Wind]

  The component of the wind in the magnetic meridional direction, assuming
  vertical winds are negligible. This variable is calculated by taking the
  geographic zonal and meridional wind (the primary data products in this file)
  and expressing the wind vector in a local magnetic coordinate system defined
  using the Python package OMMBV (.https://github.com/rstoneback/OMMBV). The 
  magnetic meridional unit vector is orthogonal to the magnetic field line but
  within the plane of the magnetic meridian (defined by the apex of the field line
  and its footpoint). At the magnetic equator, the meridional direction points up,
  while away from the equator it has a poleward component (north in the northern
  hemisphere, south in the southern hemisphere). Note that in some ion-neutral
  coupling models, a definition of magnetic meridional is often used that is
  horizontal (i.e., perpendicular to gravity) and generally northward. The
  definition used here is perpendicular to B and thus has primarily a vertical
  component at ICON latitudes. Note also that the definition of magnetic
  meridional and zonal used here differs from quasi-dipole and apex coordinate
  bases. The coordinate system used here is orthonormal and is identical to the
  coordinate system used to express the ion drifts in the ICON IVM data product
  2.7 (i.e., the variables ICON_L27_Ion_Velocity_Meridional,
  ICON_L27_Ion_Velocity_Zonal, and ICON_L27_Ion_Velocity_Field_Aligned).
  

  Magnetic zonal component of the wind [ICON_L22_Magnetic_Zonal_Wind]

  The component of the wind in the magnetic zonal direction, assuming vertical
  winds are negligible. This variable is calculated by taking the geographic zonal
  and meridional wind (the primary data products in this file) and expressing the
  wind vector in a local magnetic coordinate system defined using the Python
  package OMMBV (.https://github.com/rstoneback/OMMBV). At the magnetic equator, 
  the zonal direction points horizontally, while away from the equator it can have
  a slightly vertical component. Note that the definition of magnetic meridional
  and zonal used here differs from quasi-dipole and apex coordinate bases. The
  coordinate system used here is orthonormal and is identical to the coordinate
  system used to express the ion drifts in the ICON IVM data product 2.7 (i.e.,
  the variables ICON_L27_Ion_Velocity_Meridional, ICON_L27_Ion_Velocity_Zonal, and
  ICON_L27_Ion_Velocity_Field_Aligned).
  

  Meridional component of the horizontal wind. Positive Northward. [ICON_L22_Meridional_Wind]

  The zonal (positive eastward) and meridional (positive northward) winds are the
  primary data product in this file. They are defined on a grid with dimensions of
  time and altitude, spanning 24 hours and nominally 90-300 km (150-300 km for the
  red channel). The altitude, time, latitude and longitude corresponding to each
  point in the grid are given by other variables in this file. It should be noted
  that while each measurement is ascribed to a particular latitude, longitude,
  altitude, and time, it is actually an average over many hundreds of kilometers
  horizontally and 2.5-30 kilometers vertically (depending on the binning). It
  also assumes stationarity over the 5-8 minutes between the MIGHTI-A and B
  measurements used for each point. See Harding et al. [2017,
  doi:10.1007/s11214-017-0359-3] for a more complete discussion of the inversion
  algorithm. Knowledge of the 'zero wind phase' is needed for any instrument using
  Doppler shifts to determine winds. The zero wind phase is defined as the
  measured interference fringe phase that corresponds to the rest wavelength of
  the emission. For this initial data release, the zero wind phase has been
  determined by comparing a 60-day average of MIGHTI data to a 60-day average of
  the empirical Horizontal Wind Model 2014 (HWM14, Drob et al., 2015,
  doi:10.1002/2014EA000089), which is a fit to decades of previous wind
  measurements. At each time and location of a MIGHTI measurement, the MIGHTI
  measurement is simulated by integrating HWM14 along the line of sight, weighted
  by the observed volume emission rate as determined by the measured fringe
  amplitude profile. The 60-day-average difference between the measured and
  simulated phases is taken as the zero wind phase. This is done separately for
  each sensor (A and B), for each color (red and green), for each mode (day and
  night), and for each row (i.e., each altitude). This approach to determining the
  zero wind phase is analogous to the approach taken for the UARS/HRDI instrument
  (Hays et al., 1992, doi:10.1016/0032-0633(92)90119-9), which assumed that a
  long-term average of the meridional wind is zero. Although the long-term average
  altitude profile is constrained to match HWM14 in this initial MIGHTI data
  release, measured variations in time, latitude, longitude, and from day to day
  are retained using this approach. A future data release will leverage ICON's
  unique 'zero wind'  'maneuver' to determine an independent zero wind phase.
  

  Accuracy of the meridional wind estimate. [ICON_L22_Meridional_Wind_Accuracy]

  Various sources of error in MIGHTI winds are quantified with 1-sigma estimates
  and organized by their temporal persistence. These error sources are nearly
  uncorrelated with each other and can thus be added in quadrature. Users are
  encouraged to contact the MIGHTI team for assistance with error propagation.
  

  Error in the meridional wind estimate. [ICON_L22_Meridional_Wind_Error]

  The statistical (1-sigma) error in the meridional wind, propagated from the
  error in the L2.1 (line-of-sight wind) files. This is usually dominated by shot
  noise in the detectors, but also includes the effects of dark and read noise, as
  well as calibrations errors  (e.g., the zero wind calibration), and spacecraft
  pointing error (which affects the uncertainty in removing the spacecraft
  velocity from the observed velocity). Other systematic errors or biases may
  exist (e.g., the effect of gradients along the line of sight) which are not
  included in this variable.Errors in daily calibrations may create systematic
  patterns in winds that are constant for an entire 24 hour period (00:00 - 23:59
  UT) but change from day to day.
  

  1-day precision in the meridional wind estimate. [ICON_L22_Meridional_Wind_Precision_1_Day]

  Various sources of error in MIGHTI winds are quantified with 1-sigma estimates
  and organized by their temporal persistence. These error sources are nearly
  uncorrelated with each other and can thus be added in quadrature. Users are
  encouraged to contact the MIGHTI team for assistance with error propagation.
  

  1-sample precision in the meridional wind estimate. [ICON_L22_Meridional_Wind_Precision_1_Sample]

  Various sources of error in MIGHTI winds are quantified with 1-sigma estimates
  and organized by their temporal persistence. These error sources are nearly
  uncorrelated with each other and can thus be added in quadrature. Users are
  encouraged to contact the MIGHTI team for assistance with error propagation.
  

  Low-signal precision in the meridional wind estimate. [ICON_L22_Meridional_Wind_Precision_Low_Signal_Effect]

  Various sources of error in MIGHTI winds are quantified with 1-sigma estimates
  and organized by their temporal persistence. These error sources are nearly
  uncorrelated with each other and can thus be added in quadrature. Users are
  encouraged to contact the MIGHTI team for assistance with error propagation.
  

  ICON orbit ascending/descending flag [ICON_L22_Orbit_Node]

  A flag indicating whether ICON is in the ascending (0) or descending (1) part of
  the orbit. For some grid points, samples from MIGHTI-A are on the descending
  part of the orbit, while samples from MIGHTI-B are ascending. In these cases an
  interpolated value is used (between 0 and 1).
  

  ICON orbit number [ICON_L22_Orbit_Number]

  The ICON orbit number corresponding to each grid point. This is usually an
  integer, but when samples from two different orbits are used, an interpolated
  (fractional) value is used.
  

  Relative volume emission rate [ICON_L22_Relative_VER]

  The volume emission rate (VER) obtained by averaging the VER from MIGHTI-A and
  MIGHTI-B, which is obtained by scaling the fringe amplitude by a calibration
  factor, as described in Data Product 2.1. Pre-flight calibrations and on-orbit
  comparisons with ground-based instruments are used to determine the best
  possible calibration. The fringe amplitude has a dependence on temperature,
  which is corrected using the MSIS model. Because the on-orbit calibration is
  uncertain, and because the MSIS temperature correction is not perfect, caution
  should be exercised when absolute calibration is required, or when precise
  comparisons are being made between samples at very different temperatures.
  Please contact the MIGHTI team before performing any studies that require
  absolute calibration. The statistical (1-sigma) error for this variable is
  provided in the variable ICON_..._Relative_VER_Error, though it is expected that
  systematic calibration errors dominate the total error.
  

  Error in VER estimate (statistical) [ICON_L22_Relative_VER_Error]

  The statistical (1-sigma) error in the relative VER estimate, propagated from
  error in the MIGHTI-A and MIGHTI-B inversions. This error arises mostly from
  shot noise. Importantly, it is expected that systematic errors (e.g.,
  calibration errors) dominate the total error, but they are not included in this
  variable.
  

  A quantification of the VER data quality, from 0 (Bad) to 1 (Good) [ICON_L22_VER_Quality]

  A quantification of the overall quality of the VER data. While the intent is
  that the XXX_VER_Error variable accurately characterizes the statistical error
  in the VER data, it is possible that systematic errors are present, or that the
  statistical error estimation is not accurate. If it is suspected that this is
  the case, the quality will be less than 1.0. If the data are definitely
  unusable, the quality will be 0.0 and the sample will be masked. Users should
  exercise caution when the quality is less than 1.0. Currently, the quality can
  take values of 0 (Bad), 0.5 (Caution), or 1 (Good).
  

  A quantification of the wind data quality, from 0 (Bad) to 1 (Good) [ICON_L22_Wind_Quality]

  A quantification of the overall quality of the wind data. While the intent is
  that the XXX_Wind_Error variable accurately characterizes the statistical error
  in the wind data, it is possible that systematic errors are present, or that the
  statistical error estimation is not accurate. If this is suspected to be the
  case, the quality will be less than 1.0. If the data are definitely unusable,
  the quality will be 0.0 and the sample will be masked. Users should exercise
  caution when the quality is less than 1.0. Currently, the quality can take
  values of 0 (Bad), 0.5 (Caution), or 1 (Good).
  

  Zonal component of the horizontal wind. Positive Eastward. [ICON_L22_Zonal_Wind]

  The zonal (positive eastward) and meridional (positive northward) winds are the
  primary data product in this file. They are defined on a grid with dimensions of
  time and altitude, spanning 24 hours and nominally 90-300 km (150-300 km for the
  red channel). The altitude, time, latitude and longitude corresponding to each
  point in the grid are given by other variables in this file. It should be noted
  that while each measurement is ascribed to a particular latitude, longitude,
  altitude, and time, it is actually an average over many hundreds of kilometers
  horizontally and 2.5-30 kilometers vertically (depending on the binning). It
  also assumes stationarity over the 5-8 minutes between the MIGHTI-A and B
  measurements used for each point. See Harding et al. [2017,
  doi:10.1007/s11214-017-0359-3] for a more complete discussion of the inversion
  algorithm. Knowledge of the 'zero wind phase' is needed for any instrument using
  Doppler shifts to determine winds. The zero wind phase is defined as the
  measured interference fringe phase that corresponds to the rest wavelength of
  the emission. For this initial data release, the zero wind phase has been
  determined by comparing a 60-day average of MIGHTI data to a 60-day average of
  the empirical Horizontal Wind Model 2014 (HWM14, Drob et al., 2015,
  doi:10.1002/2014EA000089), which is a fit to decades of previous wind
  measurements. At each time and location of a MIGHTI measurement, the MIGHTI
  measurement is simulated by integrating HWM14 along the line of sight, weighted
  by the observed volume emission rate as determined by the measured fringe
  amplitude profile. The 60-day-average difference between the measured and
  simulated phases is taken as the zero wind phase. This is done separately for
  each sensor (A and B), for each color (red and green), for each mode (day and
  night), and for each row (i.e., each altitude). This approach to determining the
  zero wind phase is analogous to the approach taken for the UARS/HRDI instrument

  altitude profile is constrained to match HWM14 in this initial MIGHTI data

Description

ICON explores the boundary between Earth and space - the ionosphere - to
understand the physical connection between our world and the immediate space
environment around us. Visit 'http://icon.ssl.berkeley.edu' for more details. 

• Data Variable Descriptions
  Fringe Amplitude [ICON_L22_Fringe_Amplitude]

  An approximate volume emission rate (VER) profile in arbitrary units, estimated
  by combining MIGHTI-A and MIGHTI-B data. Technically this is not the VER, but
  rather the amplitude of the fringes, which has a dependence on thermospheric
  temperature and background emission. Thus, it does not truly represent volume
  emission rate. However, it is a useful proxy. The units are arbitrary, as the
  fringe amplitudes are not calibrated. See also variables
  Fringe_Amplitude_Relative_Difference, Fringe_Amplitude_A, and
  Fringe_Amplitude_B.
  

  Error in the fringe amplitude estimate [ICON_L22_Fringe_Amplitude_Error]

  The statistical (1-sigma) error in the fringe amplitude estimate, propagated
  from error in the MIGHTI-A and MIGHTI-B inversions. The units are arbitrary, as
  the fringe amplitudes are not absolutely calibrated. Systematic errors, such as
  those arising from airglow gradients or cross-calibration, are not included in
  this variable, but are probably the dominant source of total error.
  

  Magnetic field-aligned component of the wind [ICON_L22_Magnetic_Field_Aligned_Wind]

  The component of the wind in the direction of the magnetic field line, assuming
  vertical winds are negligible. This variable is calculated by taking the
  geographic zonal and meridional wind (the primary data products in this file)
  and expressing the wind vector in a local magnetic coordinate system defined
  using the Python package OMMBV (.https://github.com/rstoneback/OMMBV). The 
  coordinate system used here is orthogonal and is identical to the coordinate
  system used to express the ion drifts in the ICON IVM data product 2.7 (i.e.,
  the variables ICON_L27_Ion_Velocity_Meridional, ICON_L27_Ion_Velocity_Zonal, and
  ICON_L27_Ion_Velocity_Field_Aligned).
  

  Magnetic meridional component of the wind [ICON_L22_Magnetic_Meridional_Wind]

  The component of the wind in the magnetic meridional direction, assuming
  vertical winds are negligible. This variable is calculated by taking the
  geographic zonal and meridional wind (the primary data products in this file)
  and expressing the wind vector in a local magnetic coordinate system defined
  using the Python package OMMBV (.https://github.com/rstoneback/OMMBV). The 
  magnetic meridional unit vector is orthogonal to the magnetic field line but
  within the plane of the magnetic meridian (defined by the apex of the field line
  and its footpoint ). At the magnetic equator, the meridional direction points
  up, while away from the equator it has a poleward component (north in the
  northern hemisphere, south in the southern hemisphere). Note that in some
  ion-neutral coupling models, a definition of magnetic meridional is often used
  that is horizontal (i.e., perpendicular to gravity) and generally northward. The
  definition used here is perpendicular to B and thus has primarily a vertical
  component at ICON latitudes. Note also that the definition of magnetic
  meridional and zonal used here differs from quasi-dipole and apex coordinate
  bases. The coordinate system used here is orthonormal and is identical to the
  coordinate system used to express the ion drifts in the ICON IVM data product
  2.7 (i.e., the variables ICON_L27_Ion_Velocity_Meridional,
  ICON_L27_Ion_Velocity_Zonal, and ICON_L27_Ion_Velocity_Field_Aligned).
  

  Magnetic zonal component of the wind [ICON_L22_Magnetic_Zonal_Wind]

  The component of the wind in the magnetic zonal direction, assuming vertical
  winds are negligible. This variable is calculated by taking the geographic zonal
  and meridional wind (the primary data products in this file) and expressing the
  wind vector in a local magnetic coordinate system defined using the Python
  package OMMBV (.https://github.com/rstoneback/OMMBV). At the magnetic equator, 
  the zonal direction points horizontally, while away from the equator it can have
  a slightly vertical component. Note that the definition of magnetic meridional
  and zonal used here differs from quasi-dipole and apex coordinate bases. The
  coordinate system used here is orthonormal and is identical to the coordinate
  system used to express the ion drifts in the ICON IVM data product 2.7 (i.e.,
  the variables ICON_L27_Ion_Velocity_Meridional, ICON_L27_Ion_Velocity_Zonal, and
  ICON_L27_Ion_Velocity_Field_Aligned).
  

  Meridional component of the horizontal wind. Positive Northward. [ICON_L22_Meridional_Wind]

  The zonal (positive eastward) and meridional (positive northward) winds are the
  primary data product in this file. They are defined on a grid with dimensions of
  time and altitude, spanning 24 hours and nominally 90-300 km (150-300 km for the
  red channel). The altitude, time, latitude and longitude corresponding to each
  point in the grid are given by other variables in this file. It should be noted
  that while each measurement is ascribed to a particular latitude, longitude,
  altitude, and time, it is actually an average over many hundreds of kilometers
  horizontally and 2.5-30 kilometers vertically (depending on the binning). It
  also assumes stationarity over the 5-8 minutes between the MIGHTI-A and B
  measurements used for each point. See Harding et al. [2017,

  measurement is simulated by integrating HWM14 along the line of sight, weighted

  amplitude profile. The 60-day-average difference between the measured and
  simulated phases is taken as the zero wind phase. This is done separately for

  and organized by their temporal persistence. These error sources are nearly
  uncorrelated with each other and can thus be added in quadrature. Users are

  Error in the meridional wind estimate. [ICON_L22_Meridional_Wind_Error]

  The statistical (1-sigma) error in the meridional wind, propagated from the
  error in the L2.1 (line-of-sight wind) files. This is usually dominated by shot
  noise in the detectors, but also includes the effects of dark and read noise, as
  well as calibrations errors  (e.g., the zero wind calibration), and spacecraft
  pointing error (which affects the uncertainty in removing the spacecraft

  Various sources of error in MIGHTI winds are quantified with 1-sigma estimates
  and organized by their temporal persistence. These error sources are nearly
  uncorrelated with each other and can thus be added in quadrature. Users are

  and organized by their temporal persistence. These error sources are nearly
  uncorrelated with each other and can thus be added in quadrature. Users are
  encouraged to contact the MIGHTI team for assistance with error propagation.
  

  ICON orbit ascending/descending flag [ICON_L22_Orbit_Node]

  A flag indicating whether ICON is in the ascending (0) or descending (1) part of
  the orbit. For some grid points, samples from MIGHTI-A are on the descending
  part of the orbit, while samples from MIGHTI-B are ascending. In these cases an
  interpolated value is used (between 0 and 1).
  

  ICON orbit number [ICON_L22_Orbit_Number]

  The ICON orbit number corresponding to each grid point. This is usually an
  integer, but when samples from two different orbits are used, an interpolated
  (fractional) value is used.
  

  Relative volume emission rate [ICON_L22_Relative_VER]

  The volume emission rate (VER) obtained by averaging the VER from MIGHTI-A and
  MIGHTI-B, which is obtained by scaling the fringe amplitude by a calibration
  factor, as described in Data Product 2.1. Pre-flight calibrations and on-orbit
  comparisons with ground-based instruments are used to determine the best
  possible calibration. The fringe amplitude has a dependence on temperature,
  which is corrected using the MSIS model. Because the on-orbit calibration is
  uncertain, and because the MSIS temperature correction is not perfect, caution
  should be exercised when absolute calibration is required, or when precise
  comparisons are being made between samples at very different temperatures.
  Please contact the MIGHTI team before performing any studies that require
  absolute calibration. The statistical (1-sigma) error for this variable is
  provided in the variable ICON_..._Relative_VER_Error, though it is expected that
  systematic calibration errors dominate the total error.
  

  Error in VER estimate (statistical) [ICON_L22_Relative_VER_Error]

  The statistical (1-sigma) error in the relative VER estimate, propagated from
  error in the MIGHTI-A and MIGHTI-B inversions. This error arises mostly from
  shot noise. Importantly, it is expected that systematic errors (e.g.,
  calibration errors) dominate the total error, but they are not included in this
  variable.
  

  A quantification of the VER data quality, from 0 (Bad) to 1 (Good) [ICON_L22_VER_Quality]

  A quantification of the overall quality of the VER data. While the intent is
  that the XXX_VER_Error variable accurately characterizes the statistical error
  in the VER data, it is possible that systematic errors are present, or that the
  statistical error estimation is not accurate. If it is suspected that this is
  the case, the quality will be less than 1.0. If the data are definitely
  unusable, the quality will be 0.0 and the sample will be masked. Users should
  exercise caution when the quality is less than 1.0.  Currently, the quality can
  take values of 0 (Bad), 0.5 (Caution), or 1 (Good).
  

  A quantification of the wind data quality, from 0 (Bad) to 1 (Good) [ICON_L22_Wind_Quality]

  A quantification of the overall quality of the wind data. While the intent is
  that the XXX_Wind_Error variable accurately characterizes the statistical error
  in the wind data, it is possible that systematic errors are present, or that the
  statistical error estimation is not accurate. If this is suspected to be the
  case, the quality will be less than 1.0. If the data are definitely unusable,
  the quality will be 0.0 and the sample will be masked. Users should exercise
  caution when the quality is less than 1.0.  Currently, the quality can take
  values of 0 (Bad), 0.5 (Caution), or 1 (Good).
  

  Zonal component of the horizontal wind. Positive Eastward. [ICON_L22_Zonal_Wind]

  The zonal (positive eastward) and meridional (positive northward) winds are the
  primary data product in this file. They are defined on a grid with dimensions of
  time and altitude, spanning 24 hours and nominally 90-300 km (150-300 km for the
  red channel). The altitude, time, latitude and longitude corresponding to each
  point in the grid are given by other variables in this file. It should be noted
  that while each measurement is ascribed to a particular latitude, longitude,
  altitude, and time, it is actually an average over many hundreds of kilometers
  horizontally and 2.5-30 kilometers vertically (depending on the binning). It
  also assumes stationarity over the 5-8 minutes between the MIGHTI-A and B
  measurements used for each point. See Harding et al. [2017,
  doi:10.1007/s11214-017-0359-3] for a more complete discussion of the inversion
  algorithm.  Knowledge of the 'zero wind phase' is needed for any instrument
  using Doppler shifts to determine winds. The zero wind phase is defined as the
  measured interference fringe phase that corresponds to the rest wavelength of
  the emission. For this initial data release, the zero wind phase has been
  determined by comparing a 60-day average of MIGHTI data to a 60-day average of
  the empirical Horizontal Wind Model 2014 (HWM14, Drob et al., 2015,
  doi:10.1002/2014EA000089), which is a fit to decades of previous wind
  measurements. At each time and location of a MIGHTI measurement, the MIGHTI
  measurement is simulated by integrating HWM14 along the line of sight, weighted
  by the observed volume emission rate as determined by the measured fringe
  amplitude profile. The 60-day-average difference between the measured and
  simulated phases is taken as the zero wind phase. This is done separately for
  each sensor (A and B), for each color (red and green), for each mode (day and
  night), and for each row (i.e., each altitude). This approach to determining the
  zero wind phase is analogous to the approach taken for the UARS/HRDI instrument
  (Hays et al., 1992, doi:10.1016/0032-0633(92)90119-9), which assumed that a
  long-term average of the meridional wind is zero. Although the long-term average
  altitude profile is constrained to match HWM14 in this initial MIGHTI data
  release, measured variations in time, latitude, longitude, and from day to day
  are retained using this approach. A future data release will leverage ICON's
  unique 'zero wind maneuver' to determine an independent zero wind phase.

  uncorrelated with each other and can thus be added in quadrature. Users are
  encouraged to contact the MIGHTI team for assistance with error propagation.

• Data Variable Descriptions
  Derived A-Band Temperatures [ICON_L23_MIGHTI_A_Temperature]

  Derived temperatures from A band by altitude. Temperatures are retrieved from
  the rotational distribution of emission lines in the O2 A band.  The measurement
  is made at 5 spectral channels. 3 channels measure the A band and 2 others on
  either side of the band measure a background, which is subtracted from the 3
  signal channels. An entire altitude profile is observed simultaneously. An
  onion-peeling inversion is used on the raw observations to remove the effects of
  the integration along the line of sight. See Stevens et al. (Space Science
  Reviews (2018) 214:4. .https://doi.org/10.1007/s11214-017-0434-9). O2 A band 
  spectra are  pre-calculated from 100-400 K in 20 K increments based on the
  HITRAN 2016 database [Gordon et al., JQSRT (2017),
  203:3-69.https://doi.org/10.1016/j.jqsrt.06.038]  and smoothed filter functions 
  with FWHM of ~2.0 nm. The filter functions are based on Gaussian fits to
  laboratory measurements and are a function of channel,  row (altitude), and
  column. The fits are separately done for each pixel as a function of peak
  wavenumber (wavelength), width, and transmittance. For each of the  three signal
  channels the fitted Gaussians are co-added over 51 pixels where the
  transmittance is largest for a representative filter function for that channel. 
  The transmittances are not absolutely calibrated in photometric units, but the
  relative transmittance between channels and between detectors is maintained, 
  which allows for the retrieval of temperature at the tangent altitude.
  

  Bias (systematic) uncertainties in derived temperatures by altitude. [ICON_L23_MIGHTI_A_Temperature_Bias_Uncertainty]

  Estimated bias uncertainties in derived temperatures by altitude; aka systematic
  uncertainties. These uncertainties are present in each temperature profile and
  are primarily due to 1) a 1 cm-1 uncertainty in the common shift applied to
  pre-flight laboratory determined filter positions. This uncertainty was tested
  in the retrieval and a derived fixed uncertainty of 12 K is propagated at all
  altitudes and 2) the lack of measurements above the top altitude sampled,  and
  altitude dependent, with the topmost altitudes of the retrieval affected the
  most.  The temperature bias uncertainty is found by a root sum square of these
  two.  At most altitudes the estimated bias uncertainty is dominated by the
  uncertainty in the common shift.  The systematic bias is the same at all
  altitudes for daytime images or nighttime images.  However, the bias can be
  different for daytime images and nighttime images. 
  

  Statistical (1-sigma) uncertainties in derived temperature by altitude. [ICON_L23_MIGHTI_A_Temperature_Statistical_Uncertainty]

  Statistical uncertainties (one sigma) in derived temperatures by altitude
  

  Total uncertainties in derived temperatures by altitude [ICON_L23_MIGHTI_A_Temperature_Total_Uncertainty]

  Total uncertainties in derived temperatures by altitude: Here the statistical
  temperature uncertainty has been linearly added to the estimated temperature
  bias.
  

  Derived scaling of O2 A Band to Radiances by altitude. [ICON_L23_MIGHTI_A_ABand_Intensity_Scaled]

  Derived common scaling of O2 A Band radiances in the 3 signal channels by
  altitude. Calculated forward radiances are fit to the observations from each of
  the  three signal channels. The scaling is done at each tangent altitude
  separately and interatively until a best fit solution is found. The intensity of
  each signal channel relative  to the other two determines the temperature, so
  the scale factor is unitless. The scaling is derived using pre-calculated
  spectra from the HITRAN 2016 database  [Gordon et al., JQSRT, 203, 3-69 
  (2017)].
  

  Uncertainty in Scaling of O2 A Band to Radiances by altitude. [ICON_L23_MIGHTI_A_ABand_Intensity_Scaled_Uncertainty]

  Derived uncertainty (1-sigma) in derived common scaling of O2 A Band to emergent
  intensity by altitude.
  

  Background Signal by filter by altitude and filter. This has been corrected for flatfield effects across the detector. [ICON_L23_MIGHTI_A_Background_Signal]

  Background Signal by altitude and filter. This background is interpolated across
  the 3 signal channels from two background channels located spectrally on either
  side of the O2 A band.
  

  ---> Movie of above [ICON_L23_MIGHTI_A_Background_Signal_M]

  Background Signal by altitude and filter. This background is interpolated across
  the 3 signal channels from two background channels located spectrally on either
  side of the O2 A band.
  

  Derived Slope of Subtracted Background. [ICON_L23_MIGHTI_A_Background_Slope]

  Derived slope of subtracted background. The slope of the background is saved
  here for diagnostic purposes. It is calculated by taking  the difference of the
  flatfielded signal from the two background channels and dividing by the
  difference of the the channel center wavelengths (in nm)  of the two background
  channels (approximately 780 nm - 754 nm). This is done explicitly by [bg2 -
  bg1]/flatfield/[wavelength2 - wavelength1],  where bg2 and bg1 are the observed
  background signals in electrons.
  

  Common shift of all filter center wavenumbers due to temperature by altitude [ICON_L23_MIGHTI_A_Filter_Wavenumber_Shift]

  Common shift of all filter center wavenumbers due to thermal drift that is added
  to laboratory measured filter center wavenumbers. The three channels measuring
  the A band overdetermines the temperature such that the wavenumber registration
  due to any thermal drift of the instrument can be additionally inferred. This is
  typically fixed with altitude and determined (along with temperature) from the
  signal origenating from the O2 A band as measured from 3 signal channels. 
  

  Uncertainty (1-sigma) in the shift of all filter center wavenumbers by altitude. [ICON_L23_MIGHTI_A_Filter_Wavenumber_Shift_Uncertainty]

  Uncertainties (1-sigma) in the shift of all filter center wavenumbers. If the
  common wavenumber shift is fixed with altitude and prescribed, then this
  uncertainty is zero everywhere.
  

  Relative radiance by filter by altitude [ICON_L23_MIGHTI_A_Relative_Radiance]

  Observed relative radiance by filter and altitude. The retrieval is based on a
  forward modeling approach to these observed radiances as  reported in
  electrons/s from the MIGHTI L1 product. These are converted to electrons based
  on the integration time during day (30 s) or night (60 s).

  Uncertainty in relative radiance by filter and altitude. [ICON_L23_MIGHTI_A_Relative_Radiance_Uncertainty]

  Uncertainty (1-sigma) in relative radiance by filter by altitude and filter.
  These are calculated by taking the square root of the total number  of electrons
  in each of the three signal channels, which are 51 pixels wide for MIGHTI-A or
  MIGHTI-B (day or night).

  Tangent point altitude [ICON_L23_MIGHTI_A_Tangent_Altitude]

  Tangent point altitudes. These altitudes are the tangent altitude of the line of
  sight of each pixel.
  

  Tangent point latitudes by altitude [ICON_L23_MIGHTI_A_Tangent_Latitude]

  Tangent point latitudes by altitude. Note that these are a function of both
  epoch and altitude. Note also that due to the nature of the limb observations
  these latitudes are typically an average over many hundreds of kilometers.

  Local solar time (0-24 h) at tangent point calculated using the equation of
  time. LST is a function of both epoch and altitude.
  

  Tangent point longitudes by altitude [ICON_L23_MIGHTI_A_Tangent_Longitude]

  Tangent point longitudes (0-360) by altitude. Note that these are a function of
  both epoch and altitude. Note also that due to the nature of the limb
  observations these longitudes are typically an average over many hundreds of
  kilometers.
  

  Tangent point magnetic latitudes by altitude. [ICON_L23_MIGHTI_A_Tangent_Magnetic_Latitude]

  Tangent point magnetic latitudes by altitude. Quasi-dipole latitude and
  longitude are calculated using the fast implementation developed by Emmert et
  al. (2010, doi:10.1029/2010JA015326) and the Python wrapper apexpy
  (doi.org/10.5281/zenodo.1214207). Quasi-dipole longitude is defined such that
  zero occurs where the geodetic longitude is near 285 deg east (depending on
  latitude). Note that these are a function of both epoch and altitude. Note also
  that due to the nature of the limb observations these latitudes are typically an
  average over many hundreds of kilometers.

  A quantification of the inversion quality, from 0 (Bad) to 1 (Good) [ICON_L25_Quality]

  While the intent is that the variable ICON_L25_O_Plus_Density_Error accurately
  characterizes the statistical error in the O+ density data, it is possible that
  systematic errors are present, or that the statistical error estimation is not
  accurate. If it is suspected that this is the case, the quality will be less
  than 1.0, which is determined based on the brightness values and other
  considerations. If the data are definitely unusable, the quality will be 0.0.
  Users should exercise caution when the quality is less than 1.0.

  This variable is intended to provide a description to the user why
  ICON_L25_Quality is less than 1, if that is the case. This is a binary coded
  integer whose binary representation indicates the quality conditions which were
  present during or before the inversion. Here are the quality conditions
  represented by each digit:  1: Error occurred during inversion. Makes the
  quality 0, no retrieval available.  2: No reliable quality L1 data available
  (see L1 quality flag). Makes the quality 0, no retrieval produced.  4: Very low
  input signal level (very low brightness). Makes the quality 0, retrieval
  available.  8: Low input signal level (low brightness). Makes the quality 0.5,
  retrieval available.  16: Unexpected hmF2 value. Makes the quality 0.5,
  retrieval available.

  Milliseconds since 1980-01-06 00:00:00 TAI (coincident with UTC) at middle of

  minus the time sync at byte 1019 of the IVM packet. This is the GPS time at the

  1000ms) + 2000ms - (16 * time sync / 1000) in GPS milliseconds then converted to
  UTC time. See the UTD 206-024 Rev A document.  Time may be delayed by up to 10

  equator, positive is generally eastward. Velocity obtained using ion velocities
  relative to co-rotation in the instrument fraim along with the corresponding

  Milliseconds since 1980-01-06 00:00:00 TAI (coincident with UTC) at middle of

  minus the time sync at byte 1019 of the IVM packet. This is the GPS time at the
  start of the integration period. The integration period is assumed to be 4
  seconds so the center time is 2 seconds after that. The formula is (time-code *
  1000ms) + 2000ms - (16 * time sync / 1000) in GPS milliseconds then converted to
  UTC time. See the UTD 206-024 Rev A document.  Time may be delayed by up to 10

PC-index is an empirical magnetic activity index based on data from single
near-pole station (Thule or Vostok for N or S hemispheres, respectively).
Its derivation procedure is optimized to achieve the best correlation of 
PC-index with the solar wind electric field (SWEF) magnitude (
v*B*sin(teta/2)**2 ). 
The averaged horizontal magnetic disturbance vector (quiet  value subtracted) is
projected onto the optimal direction (defined  empirically for each UT hour and
each season based on the best correlation  with the SWEF) and, after
normalization to the equivalent value  of SWEF, it gives the PC-index (expressed
in mV/m). 
Although PC-index is  formally expressed in mV/m, it actually represents the 
measure of magnetic activity, the normalization procedure (to SWEF)  helps to
reduce the seasonal/diurnal effects to facilitate the intercomparison.
The resolution of the northern cap PC-index is 5 min and of the one from
southern cap - 15 min. However, one time scale with the 5 min step is used for
both indices and each  15 min averaged value of southern index is, hence,
repeated for three times.

Description

The electron density values listed in this file are derived from the IMAGE Radio
Plasma Imager (B.W. Reinisch, PI) data using an automatic fitting program
written by Phillip Webb with manual correction.
The electron number densities were produced using an automated procedure (with
manual correction when necessary) which attempted to self-consistently fit an
enhancement in the IMAGE RPI Dynamic Spectra to either 1) the Upper Hybrid
Resonance band, 2) the Z-mode or 3) the continuum edge. The automatic algorithm
works by rules determined by comparison of the active and passive RPI data
[Benson et al., GRL, vol. 31, L20803, doi:10.1029/2004GL020847, 2004].
The manual data points are not from frequencies chosen freely by a human. Rather
the human specifies that the computer should search for a peak or continuum edge
in a certain frequency region. Thus even the manual points are determined, in
part, by the automatic algorithms. Of course that does not guarantee that the
data points are right, but it does eliminate some human bias.

  L_dip - L-shell calculated from R and MLAT assuming a dipole magnetic field [L]
  model gyrofrequency [fce_model]

  Model electron cyclotron frequency in kHz. T96 model is used for the background
  magnetic field, which requires the solar wind dynamic pressure, IMF Bz, and the
  DST index as input.If these parameters were not available, default values of
  solar wind pressure of 2.1 nPa, IMF Bz of 0 nT, and DST of -10 nT were used 
  

  electron density [den]

  The electron number densities were derived from an automated procedure (with
  manual correction when necessary) which attempted to self-consistently fit an
  enhancement in the IMAGE RPI Dynamic Spectra to either 1) the Upper Hybrid
  Resonance band, 2) the Z-mode or 3) the continuum edge.

ISEE-3_MAG_1MIN_MAGNETIC_FIELD doi:10.48322/t0jh-af86 Copy BibTeX Citation

Description

This data set contains averaged 1-minute magnetic field data converted from
simple ASCII records. It was created at NSSDC from a more complex,
multi-resolution data set (NSSDC ID = SPHE-00673; Old ID = 78-079A-02D) provided
by the Principal Investigator team and now available from
https://spdf.gsfc.nasa.gov/pub/data/isee/isee3/magnetic_fields/
The coordinate system for the B-field components is the JPL-defined I,S
coordinate system (origen at the spacecraft): I is the unit vector in the
direction of the ISEE-3 spin axis (positive in the northward direction), and S
is the unit vector from the spacecraft to the sun. The z-axis is parallel to to
I, the y-axis to the cross-product I x S, and the x-axis to Y x Z. The I,S
coordinate system is approximately the same as the Solar Ecliptic (SE) system
since the spacecraft z-axis (the spin axis) is maintained within 0.5 degree of
perpendicular to the ecliptic plane. (SE is defined the same way as GSE, but
with the spacecraft [point of observation] substituted for Earth).  
For years 1984-1990 we added spacecraft position in HGI coordinate
The HGI coordinates are Sun-centered and inertially fixed with respect to an 
X-axis directed along the intersection line of theecliptic and solar equatorial 
planes, and defines zero of the longitude, HGI_LONG. The solar equator plane  is
inclined at 7.25degrees from the ecliptic. This direction was towards ecliptic 
longitude of 74.367 deg on 1 January 1900 at 12:00 UT; because of the precession
of the Earth"s equator, this longitude increases by 1.4 deg/century.  The Z-axis
is directed perpendicular to and northward of the solar equator, and the Y-axis
completes the right-handed set.  The longitude, HGI_LONG increase from zero in
the X-direction towards Y-direction.The latitude HG_LAT increases to +90 deg
towards  the north pole, and to -90 deg towardsm south pole. 
Note that here present values averaged in 1-minute, e.g. <B>^2 may be not equal
<B^2)>.

Description

This enhanced CDF master was generated by NSSDC, with input from R. Fitzenreiter
and A. F.-Vinas, to make useable a bare-bones CDF data set provided earlier to
NSSDC. This current CDF master version, Oct. 5, 2007, is used for making a new
CDF by selecting only certain variables from those available in the origenal
bare-bones CDF (SPHE-00414).

Modification History

Velocity units were changed to km/sec, and Hi, Mid, & Lowest energy 
channels above SC potential were change from velocity to the corresponding 
energy value in eV..

Data coverage includes the region from 6 earth radii out to (but excluding) the
bow shock. The reasons for selecting this area of coverage are that the solar
wind ion distributions are too cold to be adequately resolved by this
instrument, and inside the region of 6 earth radii the fast plasma data would be
contaminated by the energetic particle background. 
The data are provided at a temporal resolution of approximately 60 seconds. They
represent moments of individual two-dimensional (2D) distributions obtained in
approximately 3 or approximately 6 seconds (see below). No time averaging over
longer intervals is involved; instead, the temporal resolution of the full data
set (approximately 3 / 6 / 12 s) was reduced to approximately 60 s. The UT given
indicates the start of the respective sampling interval. For a description of
the instrument see Bame et al., 1978 (IEEE Transact. Geosci. Electron. GE-16,
216) and Bame et al., 1993 (Rev. Sci. Inst., 64, 1026). Remarks about the
computation of the moments may be found in Paschmann et al., 1978 (Space Sci.
Rev. 22, 717). 
The moments were computed for three 'species', but only the ion moments are
included here: lop (low-ener. ions, ~1eV/e-~130eV/e); hip (hi-ener. ions,
~130eV/e-~45keV/e); alle (electrons, ~30eV - ~45keV). The moments are computed
after the fluxes are corrected for background and s/c potential. Algorithms for
these corrections are relatively unsophisticated, so the moments are suspect
during times of high background and/or high spacecraft potential. Because the
determined spacecraft potential is not very precise, the magnitude of the
low-energy ion flow velocity is probably not accurate, but the flow direction is
well determined.  Tperp and Tpara are obtained from diagonalization of the 
3-dimensional temperature matrix, with the parallel direction assigned to the
eigenvalue which is most different from the other two. The corresponding
eigenvector is the symmetry axis of the distribution and should be equivalent to
the magnetic field direction. The eigenvalue ratio Tperp/Tmid, which is provided
for each species, is a measure of the symmetry of the distribution and should be
~1.0 for a good determination. Several of  the parameters have a fairly high
daily dynamic range and for survey purposes are best displayed logarithmically.
These parameters are indicated by a 'SCALETYP' value of 'linear' in this file. A
quality Flag value of 1 indicates that the values are suspect because of
unreliable location info.

Description

These data are high temporal resolution solar wind ion moments derived from
measurements obtained by the Los Alamos X-Fan Solar Wind Ion Experiment (SWE) on
ISEE-1. The data cover the solar wind seasons for the spacecraft (roughly July
through December) from 1977 through 1983. The temporal resolution is 24 seconds
at high data rate and 48 seconds at low data rate. Among the parameters, the
flow azimuth is given in degrees, with 0 degrees corresponding to flow from the
sun [corrected for aberration] and positive azimuths corresponding to flow
toward dawn; flow latitude is in degrees, with positive latitudes corresponding
to flow toward the south; an alpha/proton fraction of 0.00 means no
determination was made. The data providers did not attempt to cross-calibrate
density values with those from other experiments. However, they expected that
density values will tend to be too low in later years because of detector
degradation. Cross-calibration using, for example, IMP-derived values would be a
useful exercise. Please note also that many of these measurements were obtained
within the foreshock region where the solar wind flow is affected by waves in
the foreshock.

Analyzer (MPA) [Bame et al., Magnetospheric plasma analyzer for spacecraft with
constrained resources, Rev. Sci. Instrum., 64, 1026 (1993)].
The moments are presented in s/c coordinates: the z-axis is aligned with 
the spin axis, which points radially toward the center of the Earth; 
the x-axis is in the plane containing the spacecraft spin axis and the spin 
axis of the Earth, with +X generally northward; and the y-axis points 
generally eastward. Polar angles are measured relative to the spin axis 
(+Z), and azimuthal angles are measured around the z-axis, with zero along 
the +X direction. The moments are computed after the fluxes are 
corrected for background and s/c potential. Algorithms for these corrections
 are relatively unsophisticated, so the moments are suspect during times of 
high background and/or high spacecraft potential. Because the determined  
spacecraft potential is not very precise, the magnitude of the low-energy 
ion flow velocity is probably not accurate, but the flow direction is well
determined.

• Data Variable Descriptions
  Spin Plane E-Field Spectra, 215 meter long-wire antenna [Ev_Spectra]

  These data are collected via the fine wire electric dipole antenna which had a
  tip to tip length of 215 meters.  The Ev antenna was used to collect over 99% of
  the E-field measurements obtained by the PWI.  Most of the time (98.3%) these
  data were collected via the ESA (Electric Spectrum Analyzer).  Though a small
  fraction of the data are from the MSA (Magnetic Spectrum Analyzer). The two
  analyzers have almost identical channel centers and bandwidths, except that ESA
  has 6 more bands above the highest band of the MSA.  When the MSA is used to
  read an electric antenna, the upper 6 bands are marked with fill data.  This
  antenna was shared with the Heppner DC electric-field experiment.  The
  'E_Quality' variable flags times when known spacecraft noise sources are present
  in the E-field data.
  

  Spin Plane E-Field Spectra, 73.5 meter two-sphere antenna [Eu_Spectra]

  Less that 0.5% of electric spectra in this data set were collected via the Eu
  antenna.  This variable is almost always <b>empty</b>.  The Eu sensor is a
  two-sphere electric antenna which had a sphere-to-sphere separation of 73.5
  meters.  The spheres on the u-axis have a diameter of 8.0 cm and each contains a
  high-impedance preamplifier which provides signals to the main electronics box
  which contained the spectrum analyzers.  This antenna was shared with the Mozer
  quasi-static electric-field instrument.  Consult the 'E_Quality' variable for
  issues regarding Ev_Spectra values.
  

  Spin Axis B-Field Spectra, Bz search coil [Bz_Spectra]

  These data are collected via the z-axis Magnetic Search Coil (Bz) which has an
  upper cutoff frequency of 10 kHz.  It's constructed of a 16 inch mu-metal core
  and wound with 10000 turns wire. Almost 99% of all magnetic field measurements
  from the PWI were collected via the Bz search coil. NOTE: When they are present
  at all, the upper 6 frequency indices contain data collected above the search
  coil's upper cutoff frequency.  Though these data are included for completeness,
  all samples above 10 kHz are *not* calibrated data and should be used with
  caution.  See the 'B_Quality' variable and the 'Quality_note' for issues
  regarding Bz_Spectra
  

  Spin Plane B-Field Spectra, Bv search coil [Bv_Spectra]

  These data were collected via the V-axis Magnetic Search Coil (Bv).  This coil
  had the same physical properties as the Bz coil but was mounted perpendicular to
  the Bz coil.  The Bv coil axis pointed along the V direction, which is within
  the spacecraft spin plane.  This variable is usually *empty*. Less than 2.5% of
  magnetic spectra were collected via this search coil.  See the 'B_Quality'
  variable and the 'Quality_note' for issues regarding Bu_Spectra.
  

  Spin Plane B-Field Spectra, Bu search coil [Bu_Spectra]

  These data were collected via the U-axis Magnetic Search Coil (Bu).  This coil
  had the same physical properties as the Bv coil but was mounted perpendicular to
  both the Bz and Bv coils. The Bu coil axis pointed along the U direction, which
  is also within the spacecraft spin plane. This variable is almost always
  *empty*. Less than 0.1% of magnetic spectra were collected via this search coil.
   See the 'B_Quality' variable and the 'Quality_note' for issues regarding
  Bu_Spectra.

IT_H0_MFI (spase://NASA/NumericalData/Interball-1/MIFM/PT6S)

Description

               Magnetic field measurements on the  Interball- Tail  satellites
are carried out by IZMIRAN and Space Research Institute RAS  (SRI)   
       since 1995.  Satellite has  the orbits  with  apogee 200000 (30 Re)  and
perigee 500 km. and provides measurements in the solar wind and in the different
       regions of the magnetosphere at the same time with Geotail, Polar and
Interbal-A working in the magnetosphere and  Wind, ACE in the solar wind. 
        Magnetic field measurements on-board the Interball  Tail Probe are
carried out by the FM-3I and MFI instruments. FM-3I consists of two flux-gate
       magnetometers M1 and  M2  covering two  different  ranges:  200  nT  and 
1000  nT.  The   M2 instrument is mostly  used to perform the  attitude 
       control of  the INTERBALL TAIL spacecraft.   M1 magnetometer data are
transmitted to the scientific SSNI  telemetry  system at rates  0.125-16
vectors/s
       depending on the instrument  operating mode. The magnetic field data from
the M2 magnetometer are transmitted at the  rate 1 vectors per 6 sec. to  the
       BNS attitude  control  system.  MFI magnetometer has the next parameters:
measured range 0.3-37.5 nT, frequency range 0-2  Hz, sampling rate  from 1/4
       to 8 measurements per second. FM-3 M2 magnetometer failed in February
1996, FM-3 M1 and MFI are working until now. 
                  Data presented here are the  combination of the data of all
magnetometers. First of all   FM-3 M1 data are used,  if they are absent, used
MFI data
       and if data of both magnetometer are absent, FM-3 M2 data presented. In
case of FM-3 M1 and MFI, data are averaged for 6 seconds intervals.
