Subject: 2.5m obslog 20130410 (MJD 56393) From: doravetz@apo.nmsu.edu Date: Thu, 11 Apr 2013 12:09:20 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday April 10, 2013 (MJD 56393) ---- Observing Team ---- Audrey Oravetz Dan Oravetz ---- Observing Plan ---- 10 Apr 2013 56393.0 BOSS 8.8 hours and APOGEE morning twilight observations ---- Observing Summary ---- The first half of the night was lost to high humidity, clouds, and intermittent snow flurries. Observed the following: Cart. 15, 6739 - SOS had requested post-cals, but the SOS results for the post-cals suggest the spectrographs became out-of-focus during science observations, perhaps due to equilibration as we did not have much time to ventilate after opening shortly after weather improved. See Log for more details. Can someone advise whether this plate should be re-observed or re-plugged? Cart. 17, 6726 - SOP gotoField failed after the short hartmann sequence. We aren't sure why. The red cameras appeared to complete the requested moves. See Log and Problems Section for details. We also had a red XSIGMA value for b2 in the flat. After attempting to re-focus with full Hartmanns we still had the same red XSIGMA value. We obtained one exposure on this plate. Should we count it as 'good' given the red XSIGMA value in the flat? Cart. 4, 5910, GALCEN_A - AB @ 500s each ---- Observing Log ---- Afternoon ========= Checked STUI actors, checked mirror numbers, checked upper and lower telescope enclosure, checked fiducials, cleaned APOGEE gang connector and took APOGEE evening cals, took guider dark. Focused BOSS spectrographs: Median spectrographs temperatures: Tsp1= 5.6, Tsp2= 4.9 Outside air temperature= 1.6 COLLIMATE: Predict blue camera ring movement of -3.5 degrees for spectro-1 COLLIMATE: Predict blue camera ring movement of 3.4 degrees for spectro-2 COLLIMATE: Camera r1 appears to be IN-FOCUS (|mean| 74.20 [above 0.50] The SOS results for the post-cals suggest that the spectrographs had become drastically out of focus over the course of the nearly two hours of science integration. The median spectrograph temperatures dropped by ~3C from pre-cals to post-cals: SP1 Median Temp.: during pre-cals: 2.6C; during post-cals: -0.6C SP2 Median Temp.: during pre-cals: 2.1C; during post-cals: -1C The drop in spectrograph temperature is no doubt attributable to the fact that we were unable to ventilate for any appreciable amount of time before opening due to the weather. We also noticed that the S/N plots for the science exposures show structure across the plate that seemed to become more pronounced with the spectrographs' drop in temperature as they equilibrated; i.e., the first science exposure shortly following the focus routine from the short hartmann analysis does not exhibit any discernible pattern, but each subsequent exposure's S/N plot displays more pronounced structure which seems to correlate with the spectrographs dropping in temperature during equilibration. Can someone speak to the quality of these data given these circumstances and advise on how to proceed? Cart. 17, 6726 ************** 10:13Z - Used a combination of offsets to acquire the field. The final offsets can be found in the Offsets section of the log. Clear skies, but variable seeing. 10:14Z - Hartmanns. 10:14:33 boss exposure 4.0, file=159975 10:15:23 boss exposure 4.0, file=159976 10:18:03 hartSp2: r=741, b=2.5, txt=OK, sp2Temp = -1.2 10:18:03 sos.sp2AverageMove = -5070 10:18:17 motorPos.sp2.move: -5069, -5066, -5069 10:18:17 hartSp1: r=-910, b=-3.1, txt=OK, sp1Temp = -1.0 10:18:17 sos.sp1AverageMove = -4597 10:18:29 motorPos.sp1.move: -4597, -4599, -4597 SOP gotoField failed after the Hartmann sequence and before the cals started. The red camera collimator moves seemed to complete and we didn't notice any warnings about the residual blue ring movements being too large. See Problems Section for relevant information from STUI Logs. The only thing we could figure is that the pixel difference between b2 and r2 was 0.42 and so even after moving r2, the best case would put r2 and b2 |0.21| pixels from focus. The tolerance for 'in-focus' is |0.2| pixels for the short hartmann focusing, so is this what tripped the failed gotoField? On the next gotoField attempt (with Hartmanns) everything completed without complaining. 10:22Z - Hartmanns. 10:22:32 boss exposure 4.0, file=159977 10:23:23 boss exposure 4.0, file=159978 10:24:20 hartSp2: r=1321, b=4.5, txt=OK, sp2Temp = -1.5 10:24:20 sos.sp2AverageMove = -527 10:24:25 motorPos.sp2.move: -528, -528, -528 10:24:25 hartSp1: r=-703, b=-2.4, txt=OK, sp1Temp = -1.1 10:24:25 sos.sp1AverageMove = -320 10:24:29 motorPos.sp1.move: -319, -320, -319 10:24Z - Cals. 10:24:49 boss exposure 4.0, file=159979 10:26:24 boss exposure 30.0, file=159980 - red b2 XSIGMA 10:33Z - Science. 900s exposures. 10:33:58 boss exposure 900.0, file=159981 - aborted this exposure when we saw the red b2 XSIGMA value. 10:39Z - Full hartmanns to try and remedy the red b2 XSIGMA value. 10:39:37 boss exposure 4.0, file=159982 10:41:03 boss exposure 4.0, file=159983 10:48:33 boss exposure 4.0, file=159984 10:49:58 boss exposure 4.0, file=159985 We adjusted b2 +3 degrees according to the Collimate output. It had asked for +6 degrees with r2 in-focus, so we split the difference and moved b2 +3 degrees. The following set of cals showed b2 still with a red XSIGMA value. Not sure why the movement of the b2 ring in the requested direction did not improve the SOS output of the cals. 10:56Z - Cals. 10:56:01 boss exposure 4.0, file=159986 10:57:37 boss exposure 30.0, file=159987 - red b2, yellow b1 XSIGMA 11:00Z - Science. 900s exposures. 11:00:03 boss exposure 900.0, file=159988 11:16:25 boss exposure 900.0, file=159989 - aborted because we weren't going to finish this plate under these conditions and we had time to obtain some APOGEE data.
