Darryl suspected there may still be a quad cell problem when the images are far off-center. Haosheng concurred with that and was going to reduce the offsets and load the program mods at some point--he hasn't alerted us that this was done so I don't know if he did this--although the offset values appeared to be the same during the 1900 UT flat-field cal this morning. What I found while watching the program run on the sparc and the PC was that focus was not changing(!!) Images were fine for the 2000 series data and I recall seeing the "position = xxx.xxx" values change according to the "fcs goto xxx.xxx" request. During the 2100 series, the "position =" values went to 58 (or was already there) on the first exposure and THE VALUE DID NOT CHANGE FROM 58 the whole time during the image subset where a bunch of exposures were made with the focus changing between each exposure. The first exposure subsets, before the focus series, were in good focus. The result of this focus failure was the RED images were out of focus. The BLUE and CAK focus change requests must have been close enough to 58 that the focus was not too hosed (50-450 or so?). Red focus requests were for 1600-2000, quite far from 58, no? Tried requesting focus changes manually from PC after the 2100 series finished and go no response. In thinking back to yesterday, the out of focus images occurred in the later series-- probably 2100, definitely 2200. One troubleshoot path would be to determine if the focus stall is a time-of-day (spar position) thing or a thermal thing, or ????? I will look at the U2A and U2B outputs during the next series to determine that the active mirror is NOT oscillating and the focus iss the only thing causing this particular out-of-focus condition. this should put the active mirror problem to bed as "fixed by Koon". COMMENT: Tue Mar 7 21:52:11 GMT 2000 AARGH! forgot to reconfigure dome shutter. CHIP domed out. I will stop CHIP rather than reconfigure dome at this late time.

I watched the U2A and U2B outputs on the scope and the values did not change or show oscillation during the out-of-focus RED images. All RED images during the 2200 series, including during the first two subsets, were out-of-focus. Position = values were not changing to fcs goto requests. There is a definite problem with the focus mechanism. It was good yesterday morning and again this morning. Problem is definitely intermittent, not totally failed.
