After the Hidalgo, Mexico Earthquake lockloss, ISC_LOCK went for LOCKING_ARMS_GREEN, and it appeared to get there with no problem, but the weird thing I noted was ISC_LOCK thought we were in LOCKING_ARMS_GREEN, and the values for ALS x & y on NDSCOPE both looked nominal (over 1.0 counts), BUT the video spot for ALSy did not look right.
Instead of a bright 0:0 mode for ALSy, we had a very faint spot---and ISC_LOCK & green arm power looked OK! (see attached screen shot)
I unlocked green Y, tweaked alignment only a little, but it would do the same thing. I would actually see a nice bright 0:0 mode, but it would then immediately drop in intensity on the video (perhaps in 2-steps).
ISC_LOCK was happy so I moved on. Still waiting to see if we can live with this (1st attempt did not lock DRMI, so trying it again).
Watching the ALSy video a few more times, it looks as if there are 3 steps down in the power (by my eye watching the video).
Mentioned this to Sheila and her thought was this might possibly be an issue with the Video for ALSY
This Is A New Issue/Feature!
I found that the auto exposure was set to "ON" and the value slider was all the way down. I turned auto exp "OFF" and turned up the exposur to match that of the X camera. It seems to have stayed through another IA/Locking process(es).
July 18th at 13:20 PDT the auto exposure was turned on, most likely by accident. Ed restored this to the x value, I'll restore it to the previous value of 100000 if we lose lock (I don't know if this is an accepted SDF).
