We spent two days/night working with the twilight monitor on the summit. Stubbs brought the ioptron mount, the photodiode and the tripod to the summit. There were an electrometer with the Camera team.
First Day:
I had issues setting up the summit keysight electrometer. The issue was solved by writing a usdev rule.
The instructions for setting up a key sight electrometer were updated on the wiki page.
A failed attempt to implement an asynchronous script to measure the mount position while acquiring the electrometer data.
Mount: script to slew up in elevation, take five measurements along the way, then slew to the right in azimuth, slew down in elevation, and take 5 measurements. Each slew had a fixed amount of seconds.
Second day:
Mount: script to start at Alt=80deg then do a slew down for four points. Come back to Alt=80 and slew down again. Here, I improved the algorithm by measuring what is the expected
Lessons learned
The async code is actually harder than I thought I should make a simple algorithm.
Slewing for a fixed period is not repeatable. The mount does not always comeback to the same position.
