18 May 2011 UT: BP11, LBC Collimation Model Temperature Dependence

Observers: Andrew Rakich, John Hill, Olga Kuhn, Paul Grenz (working on LBC BP11 SW) (Tucson)
OSA: Steve Allanson (LBTO)

Relatively high humidity at start of night (89%), but we are open.

19:50 Preset to WT10_401. Focus/Collimate with dofpia, /First Exited with estimated seeing 2.91 B and 1.72 R.

19:59 lbcrangebal: 030058 B and 030050 R
Sending the calculated optics offsets:
SX: dX = -0.168 dY = -0.210 dRX = -4.511 dRY = 3.603 <br>
DX: dX = 0.101 dY = 0.156 dRX = 3.339 dRY = -2.156

20:00 (ambient is LBTTEMP)
SX: Tg/Ta/ambient = 4.335/1.472/0.1
DX: Tg/Ta/ambient = 0.946/1.477/0.1

20:04 Check lbcrangebal with images 030645 B & R. lbcrangebal crashes when B & R have same timestamp! Edited lbcrangebal in Sandbox to prepend "b" and "r" to filenames.

20:10 Again --- 31208 B 31204 R Sending the calculated optics offsets:
SX: dX = 0.025 dY = -0.058 dRX = -1.236 dRY = -0.540 <br>
DX: dX = -0.029 dY = 0.056 dRX = 1.199 dRY = 0.621
Creating proxy IRCL for LBC on prime left

20:10 While rangebalancing, John has taken some guided images with LBC --- Guiding is not working. This turns out to be a truncation problem in the GetRotatorTrajectory call. See Issue 3374 and further tests below.

20:15 Slew to field at 15 30 19.84 +69 58 55 (2000) which should be up and above am>1.5 all night.

20:18 Collimate at this field with dofpia, /x2 Collimated in 4 iterations, est seeing 1.46 (R) and 1.39 (B) (?)

20:26 Starting experiment. dofpia, /X2, RedLimit=10, BlueLimit=10
Steve is trying to drive SX temperature down. DX is stable. Current SX/DX temperatures are: SX: 4.2/1.15/-0.1 (Tg/Ta/ambient)
DX: 1.02/1.20/-0.1

20:43:
SX: 4.05/0.99/-0.2
DX: 1.03/1.13/-0.2

21:00 Around this time there dofpia complained that the data files did not appear in time. They apparently just took longer than expected. Hit return and it continued. Files slow to arrive were 040854 B, 040643 R

21:14:
SX 3.51/0.787/-0.2
DX 0.974/0.920/-0.2

21:23: Stopping this experiment, and John H is going to test guiding. (Note C00 on SX = -116).

21:30 Red Trackers RPC error. And guiding doesn't seem to be working correctly - always sending the same offsets to mount. Mirror looks like it is doing what is expected (Pointing offsets on PSF about 1/2 the accumulated mount offset at the end of the exposure). Red trackers failed during this exposure.

21:51 Slewing back to 15:30:19.84 69:58:55 1sec exposure is 045331 B and 045

21:52 Restart dofpia (dofpia, /x2, RedLimit=10, BlueLimit=10)

21:53:
SX: 2.59/0.55/-0.2
DX: 0.69/0.43/-0.2

22:00 The initial SX Z4 correction is large. Andrew reanalyzing results from last FPIA temperature run - the problem was that run took place with a non-zero temperature term, while in the analysis this was taken to be zero.

22:21 John noted that, during the exposure, the rotator angle displayed on the UI was not updating. The not-well-guided images he took earlier show rotational trailing. lbc logfile shows:
2011/05/18 05:23:27.298712 W B ROTATOR           no valid position in the supplied trajectory then tracking is disabled [src/rotator/rotator.c:1739]

22:46
SX: 1.79/0.34/-0.4
DX: 0.24/0.056/-0.4

22:56 Updated BP11 LBC collimation models. Restart dofpia at 22:58.

23:00 LBC Red has hung in preset/expose/save. There is an LBCB image, but not an LBCR one. I stopped the OB finally, but all buttons are greyed out. Did lbckill.sh followed by lbcstart.sh and it is now "restarting after a crash", on its own. Red Camera did not come up (probably "restarting after crash" did not power cycle the PC). Turn off/on.

23:11 Paul recompiling LBC code. He increased the precision from 6 to 14 digits.

23:24 Blue failed to fit pupils. lbcb.20110518.062529.fits On the next one (without any corrections), fpia did calculate corrections. With this coma, only 1 pupil was fit. When coma was corrected, about 6 pupils were found.

00:25 FPIA exited with an error

00:25 backout and restart to converge.

00:29 Exit dofpia with "S" and restart for red only. dofpia, /x1, RedLimit=10, /redonly

01:05
SX: 0.229/-0.324/-1.6
DX: -0.650/-0.875/-1.6

01:12 Restarted dofpia on both sides. Results look good.

01:16 Steve starting to drive up the SX M1 temperature.

01:33 Noticed that the Command=Setpoint on SX. Steve needs to go to defrost mode on heat exchanger.
SX: -0.027/-0.393/-1.7
DX: -0.759/-1.060/-1.7

01:36 Steve is closing for high humidity - it was rising the last ~30 minutes and reached 95%.
