No coronal activity TAPES: MKIII: H01421 DPMON: P00745 CHIP: C00162 LOWL: L00421 MKIII COMMENT: Wed Oct 23 23:54:51 GMT 1996 I tried a bunch of swaps after a further attempt to align the detectors using the height mask. Swapped most of DCSB cards with chan 0 but kept seeing the same results. Light corrector table pegged most of upper half. Correct seems to only affect lower pixels and upper pixels remain highly on the negative side in P-S waveform. Also tried reducing P+S gain and Line driver gain to no avail. I tried swapping optical channels at the line driver input and did a correct on chan 1 using chan 0 detectors and preamp. THAT WAS SUCCESSFUL! The problem seems to be above the line driver. I tried one last effort--I put the compensator plates back in, with no attempt to refocus. I got the same response as with them out. I removed them again and tightened down the preamp which was a little loose. tried one last correct and got the same corrector response. Regrouping on the drive down where I sometimes come up with great ideas.... or at least good critiques of work done.
