DX

02:24

Waiting for LUCI to finish twilight flats.

02:37

Doing Alfio's software update on DX.

NCPA and GOPT gui both working. 8.65 mag star, 8.7 on wfs.

02:52

Restarting arbitrators to implement changes that Alfio suggested, to fix ICE communication issue.

Arbitrators still running, a good sign. They both crashed last night, when the fix didn't work.

02:55

New preset

03:23

During offset, gopt process is still running which sent made the optical gain go to very strange and high values, until the loop opened.

03:30

The Gopt process should pause during an AO pause, or at least stop trying to update optical gain. I don't know why it doesn't.

I think that the process uses invalid values to calculate the ratio before the system is ready to take valid data. When the loop paused, the ratio went to 1.0 and the mirror was over-driven by by a factor of 3.
During the pause, the gopt process is still running and it saves frames and makes its calculations while the loop is paused. The GOPT gui still says "running" when the loop is paused.
