	Notes from 2015Jun11.. Gain settings of tel wfs : X -0.020, -0.02 (+0.005, Y -0.005)		Notes from 2015Jun11.. Gain settings of tel wfs : X -0.020, -0.02 (+0.005, Y -0.005)

			Fri June 12 2015

			AO Testing:

			Closed loop (of telescope wfs with tip/tilt) of a bright star Vega [On sky woohoo].


			Saving WFS data from both wfss under various settings.

			I'm calling the wfs at the telescope TWFS!

			Both wfs cameras set to 200Hz. (Typically runs 194 - 206 Hz)

			Loaded Def to DM in lab. Use 'Scope' to align on Lab WFS.

			Saving 10,000 on LabAO.
			Saving 10,000 on TWFS. -> no indicator that data is being saved on TWFS. Have to check for files...

			Everything is frozen on the lab side.... too many frames? out of memory?? oops.

			10,000 is too many. Had to restart LabAO server.

			Retrying with 200 frames:
			Saving 200 frames on LabAO -> looks like it is saving data.
			Saving 200 frames on TWFS -> looks like its doing something...maybe.


			Saving 100 frames on TWFS
			Saving 200 frames on LabAO


			File number 6 for both TWFS & LabAO. TWFS: 200 Hz CLOSED loop with TT. LabAO OPEN loop with default flat.
			Hangs on 1000 frames, hopefully just freezes when saved

			File 7: same as 6.
			File 8: same as 6.

			File number 9 for both TWFS & LabAO. TWFS: 200 Hz CLOSED loop with TT. LabAO CLOSED loop with default flat.
			Files 10 & 11 same as file 9. File 11 may have lost range on TT.

			Taking 3 additional sets: 12, 13, & 14. Same as 9, 10, & 11.

			Open all loops!!!!!

			Some motion tests.
			Collecting data as it drifts. All loops open.
			File 15, 16, 17, & 18

			Looks like the beacon was on through those tests.

			file 21. moved the telescope and saved while moving.
			file 22. same test, opposite direction on the same axis.

			at the end of the dataset1, the az/el was +65,+76.
			-------------

			going to new star Alp CRB (at 1:30am)
			az,el +264,60.

			took some test files.

			taking simultaneous data with default lab ao dm with tiptilt closed on telAO.
			#25,26,27
			(note theres is a big time dealy between when we lose light in tel WFS and lose light in labAO -- artifact? latency?)

			looking at beacons for reference.
			28,29,30 (note tel WFS is a bit saturated)

			closing loop on will repeat with star light using static-correct wavefront,
			will run lab WFS for beacon at 50 Hz for higher snr
			31,32,33
			beacon: 34 (same exact settings). missing many spots../
			beacon: 35 (using default DM)
			(i expect to see some problems compared ot last one sincce I'm not suing the default DM)

			next: I will use servo on beacon. SET FLAT
			go back to star and take some data as parallactic angle changes.
			beam seems to be vignetting on lab ao. could be due star out of focus (tel wfs say s focus -1.4)
			** need s2 secondary mirror motors working !! *
			36, 37,38,39
			current az,el: 271, 51.


			Some things we need:
			1) TT needs to off load to telescope tracking when out of range.
			2) we need focus tiptilt, etc to be the same SCALE and meaning on LABAO and TELWFS. I might be running wrong version??
			3) need way to tweak beacon on reference offsets on camera (?) similar to LAB, SCOPE button?
			4) labaogtk crashed many times. more often i think when saving data.
			5) terms seem affected by subapertures with low flux. how can we auotmatically set up the clamping?
			6) how to do co-adding on labao camera?
			7) when in closed loop, we should have some way to know how much defcous/astigmatism is 'tuned in"
			8) we sholdn't need to repeatedly click on 'set flat' when closing loop on labao
			9) labao rate was super slow (1 Hz) when overlaying boxes from wazoo.
			10) should we put in a safety loop so emccd can't cool down too fast and cause damage? are we supposed to keep on?
