Hi Valentijn,
>Tom, do you have the latest msg server code, i saw that the people at
>Winsconsin made the follwoing improvements (22 October):
>
>* updated MSG servers to allow multi-band requests in IMGCOPY [12597]
>* added EUMETSAT's suggested MSG visible calibration fix [12672]
The 12597 inquiry mods are included in the current Unidata McIDAS distribution.
The 12672 inquiry mod was included in the SSEC v2004a addendum, but
it has not been included in the Unidata distribution (yet).
I just read the inquiry (from Marianne Koenig to SSEC/MUG), and the
modification is trivial, add one line in kbxmsg.dlm.
At line 151 of ~mcidas/mcidas2004/kbxmsg.dlm you should find the line:
XTEMP = ( REAL(ITEMP) * GAIN ) + OFFSET
Change this to:
XTEMP = ( REAL(ITEMP) * GAIN ) + OFFSET
IF (XTEMP.LT.0.0) XTEMP = 0.0
After making the editing change, rebuild McIDAS using:
<as 'mcidas'>
cd mcidas2004/src
make <- using vendor-supplied compilers
-- or --
make VENDOR=-g77 <- using gcc/g77 on systems where this
combination is not 'vendor' (e.g., Sun,
HP-UX, IRIX, OSF/1).
If you are on a system like Linux, typing 'make' or 'make VENDOR=-g77'
are equivalent.
After the rebuild, reinstall the binaries:
make install.bin

Thanks for the update. I just FTPed the file and will take a look
as soon as I can.

Right. You can access the Windows shared drive using Samba, can't you?

OK.

This sounds complicated. I will have to work my through the procedure/data
before being able to make an intelligent comment.

OK, thanks for the pointer.

Sorry for the delay.
Cheers,
