Telescope and AGw Commissioning at LFBG with IRTC - 06-07 April 2009 MST

Observers: J. Hill (mtn), D. Thompson (Tucson, first half), A. Rakich (Tucson), J. Storm (Potsdam)
Telescope Operator: D. Gonzalez Huerta
Telescope Support: D. Officer, G. Holmberg

Summary

First night of decent seeing all week. We probably averaged 0.6 arcsec FWHM for the night.

Took a set of AGw transformation data on M67 for Jesper in much better conditions than the previous night. However, Jesper hasn't been able to make sense of the residuals from his fit. Even with that the guide stars are typically found within an arcsec.

Adjusted M2 to -3.5" tip. Took a good set of field data in ~ 0.5" seeing.

JMH: I applied this -3.5 arcsec tip to both the IRTCF and LUCIFER collimation models SXSMLUCIFERCollimation.dat and SXSMIRTCFCollimation.dat on 08-APR-2009.

Had lots of problems with Azimuth servo. It was often running above 0.7 arcsec rms, and once started oscillating to 4 arcsec rms. Probably this is the main thing the guider has been fighting. Also lost time to azimuth jumps cancelling presets by going off-source "setting none mode".

Took a few cubes of vibration and tracking data with different samplings. But, remember caveat of azimuth servo problems.

Found some problems with GCS and IDL reporting different WFS numbers. Tried to troubleshoot with different parameters but certainly need some input from Doug.

Azimuth pointing was drifting at the beginning (opposite of last night when elevation was drifiting and azimuth was steady), but things stabilized after the temperatures evened out.

Based on what the "hbsel" page is reporting, the oil pads are still running 2 degC too warm compared to ambient or the C-Rings. (John is lobbying to put the offset back to -10 degC.)

New parameters for sextractor in GCS are much better for faint stars. The impressive example was when it grabbed a diffraction spike and pulled in the guide star from outside the field. We have not yet tested it with blurry images (seeing too good).

Had several problems with GCSL hanging, although not all of them are the fault of GCS. Once we sent 2 presets at once, and GCS didn't like this. Other times GCS seemed to be preoccupied with AzCam even before we needed an image.

Details

18:52 authorize as IRTC

18:52 Open shutter doors, T=+3 degC, D=-17degC, Wind 4 m/sec from West, sky mostly clear but not photometric. Open vent doors. Mirror at +0.7 degC.

19:00 Start Left mirror ventilation only.

19:02 Reset encoders 88, 180.

19:08 copied oacontrol.conf.basic20090406 into /etc/oacontrol/oacontrol.conf to get Jesper's new transform. The version we were using last night with the hotspot on rotator center is oacontrol.conf.20090405good

19:09 Telescope runs away in azimuth during encoder reset process. It apparently got into a state where all 4 encoders are disabled. It turned about 100 degrees before we noticed what was going on.

19:15 restart oacserver and AGw

19:51 focus 0 - a few iterations of active optics have given us 0.55-0.75 arcsec seeing, and from the 400 nm rms we know that the dome seeing hasn't settled down yet.

23:35 adjust M2 -3.5" Tip, reset IE CA accordingly IE = -141 CA = -79

23:45 AGw stopped sending images to IDL for some reason, had to stop AGw and restart it (turned out the OACserver had frozen up, stopped and restarted that too, then had to kill and restart GCS as well).

23:55:14 GCS was hung up at the end of this AGw restart business, waiting for an image though it hadn't been asked to.

2:12 Doug, the GS0 after the last GS18 in the above table has a little confusion, I lost guiding halfway through, then resent the GS0 preset with the wrong PA, I'm not too worried though because it's ontly the first GS0 measurement after the off-axis GS measurement I'm generally interested in.

2:58 IDL and GCS are reporting quite different numbers (several hundred nm) for WFE, seems that Z4-Z5 and Z6 differ the most. See WFSC 138-144 in /Repository/GCSfiles/dailyimages

02:59 Setting None mode

03:03:50 Setting None Mode - Azimuth axis oscillating 4arcsec rms. azhold, azslewtotrack

Studying off-axis convergence

04:02 pointto BS9177 going to GS=0 (Just got the following email from Doug)

"Do you or John check that the new hotspot and lenslet values are still in the GCS config file? If they are changed on the mountain and Torsten sends up a patch, they are sometimes overwritten (if Torsten has old numbers)".

04:09 going to GS 63 while John follows up on Doug's suggestion. John has checked and the IDL and GCS and "lenslet edge" and "pupil centre" are the same in IDL and GCS.

04:15 John has found that the numbers for the abovementioned parameters in IDL are not updated to Doug's latest suggestion, but the numbers in GCS are. Unfortunately, the current values in IDL seem to work better as IDL has been converging nicely, where as GCS has flipped out a couple of times in collimation.

04:18 restarted IDL with Doug's numbers, so should match GCS (but GCS is not converging so well) in /Repository/GCSfiles/dailyimages wfsc 196-214

04:28 So the reported WFS data in IDL and GCS now matches to the usual tolerances, but WFS seems not to converge as well as IDL was doing with the original paramater values used for most of tonight, so now we are changing both GCS and IDL back to IDL's start-of-the-night values. John suggests that we just revert the "lenslet edge" parameter to the start-of-the-night value and leave the Pupil centre at Doug's new value, so we'll try that. (These changes are saved for IRTC but not Lucifer.)

04:36 "lenslet edge X" = 394.95 "lenslet edge Y" = 227.15 /Repository/GCSfiles/dailyimages wfsc217-222

(still on BS9177 GS63). wfsc 218 looks like it has slightly elongated lenslet images.

04:45 Converged to < 200 nm for a couple of successive iterations. now re-sending the preset with a different PA so that Doug can get some data with non-zero values of X.

04:51 So this is interesting. Even though IDL and GCS now have the same parameters (and IDL was restarted) we now have different numbers again in IDL and GCS WFS data. SO we are restarting GCS and trying again. Funny thing here is that IDL and GCS were giving the same numbers when x=0, but diverged when x=~-90 mm. wfsc-223-226

04:55 IDL and GCS still reporting different numbers in WFS data. wfsc 228-232

04:58 didn't converge so well. Now changing PA to 56 (the other sign of X) and taking wfsc data 233-238

5:03 noticed something else odd here. Originally sent a preset with PA=INDEF so x=0 (on GS63) . Then changed the PA from 88.2 degrees to 120 degrees. Got a stage position of -89.846 X and 457.818 Y. Then changed the position angle to 56 degrees which is the same distance from the original PA in the opposite direction and got a stage position of 99.54 X and 464.045 Y. So this should have been symmetric shouldn't it?

5:13 So, it turns out that we have non-zero X with PA=INDEF, as can be seen with all the WFSC data taken earlier tonight. Now we have reset the pupil position parameter to teh start-of-the-night-for-IDL value in both GCS and IDL and are taking more data with PA = 88.6 (INDEF). Stage (X,Y) = (3.77, 433.70). We are still converging to the ~500 nm level (wfsc 242-246), so now we will try opening the vent doors and see if that is the main problem here.

5:20 vent doors have been open for several minutes, wfsc 248-252. Now even though we should have the same parameter values in both IDL and GCS, and we are PA=INDEF (x close to zero) the GCS and IDL reported values are diffrerent by quite a lot again. Doug, please try to make sense of this!!!

Close

5:29 shut for dawn. T=+3.6 degC, D=-11 degC, Wind 6 m/sec from W - very steady. Sky clear.
