Subject: 2.5m obslog 20211004 (SJD 59492) From: doravetz@apo.nmsu.edu Date: Tue, 5 Oct 2021 11:37:21 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday October 04, 2021 (SJD 59492) ---- Observing Team ---- Kaike Pan Dan Oravatz (remote) ---- Observing Plan ---- Focus vs. altitude tests off the axis ---- Observing Summary ---- We obtained one set focus vs. altitude under marginal conditions. The seeing is not very stable during the process. The best focus changes between 225, 200, and 175 um. We used (Az=0, alt=65) as a calibration point. we attempted to get a data point every 3 degrees in altitude. If we see the best focus changes (e.g. from 225 to 200 um), we check if the best at alt=65 also changes. Even focus doesn't change at different altitudes, we still slew back to alt=65 deg after get 5 to 7 points (i.e. altitude change 15 to 20 degrees). The data set indicates the optimal focus doesn't change much, not more than 25 um from altitude = 86 to 20 degrees at 1 deg off the axis. ---- Observing Log ---- Afternoon: ========= Restart TPM to make version on TPM gui match the actual version: 1.2-1-g4cea, the current git version. Apogee evening cals and FPI data are taken and checked, they are good.

Night: ====== 03:10Z: it has been two hours since we open, check whether the systems are in the thermal equilibrium. 03:40Z: I ran several focus sweep, the focus is still drifting, the wind is changing direction too. 04:00Z: Try to find stars at 1-deg. Home the stage, the setup for 1_deg field. For the field AZ=-1.6, Alt= 68.5, find the star at 256, 199. We see stars with 40 pixels on five fields. At the same (AZ, Alt), stars locates at the same spot, the procedure is fine. 04:30Z. The focus sweep data doesn't form good parabolic curves, and the best focus jumps. We decided to wait. 06:15Z: we have three consecutive focus sweeps indicating the same best focus at 275. Start the test: focus vs. altitude at 1-deg.

Looks like that focus doesn't change with altitude. The seeing is not very stable during the process. The best focus changes between 225, 200, and 175 um. We used (Az=0, alt=65) as a calibration point. we attempted to get a data point every 3 degrees in altitude. If we see the best focus changes (e.g. from 225 to 200 um), we check if the best focus at alt=65 also changes. Even the best focus doesn't change at different altitudes, we still slew back to alt=65 deg after get 5 to 7 points (i.e. altitude change 15 to 20 degrees). The data indicates the optimal focus doesn't change much, not more than 25 um from altitude = 86 to 20 degrees at 1 deg off the axis. The wind direction is AZ=115. Let's take another set of data by pointing the telescope to the opposite direction, AZ=290. 08:15Z The seeing is not stable. Wait. We checked the seeing/best focus stability about every ten minutes, but the best focus between consecutive focus sweeps was variable by ~25-50 um, so we continued to wait and sample the conditions. 11:15Z - Called it a night and closed. ---- Mirror Numbers ---- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A: 0.0060 0.0080 Axial B: 0.0310 0.0330 Axial C: -0.1150 -0.1140 Trans D: -0.0375 -0.0395 Lateral E: 0.3315 0.3310 Lateral F: 0.5345 0.5335 GALILS Commanded: 12500 -1600 5350 47050 -8800 -8400 Actual: 12500 -1600 5350 47050 -8800 -8400 SETMIR VALUES PrimDesOrient: 0.0 -59.3 -8.75 -512.73 1906.51 PrimOrient: 0.01 -59.26 -8.77 -512.68 1906.6 SECONDARY: ---------- Focus: 0.0000 Air temp: 10.78 Altitude: 29.999996178438877 MIGS TONIGHT NOMINAL Axial A: -9.4590 -9.4610 Axial B: -9.4780 -9.4760 Axial C: -9.5040 -9.5050 Trans D: 0.0980 0.0880 GALILS Commanded: 4631065 4630369 4649519 -50 -3450 Actual: 4606922 4607269 4607105 -50 -3450 SETMIR VALUES SecDesOrient: 3657.0 0.0 0.0 0.0 42.22 SecOrient: 3656.92 0.05 0.06 0.04 42.65 ---- Telescope Status ---- 00:45Z Started ventilation 01:05Z encl25m : open 05:16Z encl25m : closed Status at close: Telescope stowed at: 121.0, 30.0, 0.0 mount Instrument mounted: engCam Counterweights at: 420 ---- Software Used ---- STUI : 1.7.12 alerts : 2.1.4 apo : 3.0.0 boss : 6.0.0-alpha.0 -boss.specMec : Offline guider : 4.0.0 ecamera : 2.3.0 fliswarm : 0.1.1-alpha.0 hartmann : 2.0.0 hub : 5.0.0a0 mcp : 2.0-7-g8799 -mcp.plc : 34 -mcp.azFiduci : v1_146 -mcp.altFiduc : v1_146 -mcp.rotFiduc : v1_146 TPM : 1.2-1g4cea, the most recent git version. sop : 0.1.0-alpha.0 tcc : 1.4.0 apogee : not availble apogeecal : not availble apogeeql : v1_7_0dev STUIAdditions : origin/sdss5 ---- APOGEE Data Summary ---- [observer@sdss5-hub: ~]$ sloan_log.py -am 59491 --morning ================================================================================ APOGEE Data Summary ================================================================================ MJD UTC Cart Exposure Type Dith Reads Arch Seeing -------------------------------------------------------------------------------- 59491 23:28:12 19-0 39290009 Dark A 60 a-b-c 0.0 59491 11:39:38 19-0 39290010 Dark A 60 a-b-c 0.0 59491 11:50:16 19-0 39290011 Dark A 60 a-b-c 0.0 59491 12:00:54 19-0 39290012 Dark A 60 a-b-c 0.0 59491 12:11:46 19-0 39290013 Quartzflat A 10 a-b-c 0.0 59491 12:13:33 19-0 39290014 Quartzflat A 10 a-b-c 0.0 59491 12:15:21 19-0 39290015 Quartzflat A 10 a-b-c 0.0 59491 12:17:12 19-0 39290016 ThAr Arc A 12 a-b-c 0.0 59491 12:19:24 19-0 39290017 UNe Arc A 40 a-b-c 0.0 59491 12:26:34 19-0 39290018 ThAr Arc A 12 a-b-c 0.0 59491 12:28:46 19-0 39290019 UNe Arc A 40 a-b-c 0.0 59491 12:36:02 19-0 39290020 Dark A 30 a-b-c 0.0 59491 12:41:23 19-0 39290021 Internalflat A 30 a-b-c 0.0 59491 12:46:42 19-0 39290022 Internalflat A 30 a-b-c 0.0 59491 12:52:02 19-0 39290023 Internalflat A 30 a-b-c 0.0 59491 12:57:23 19-0 39290024 Dark A 30 a-b-c 0.0 ThAr Offsets: ['nan', 'nan', 'nan'] UNe Offsets: ['nan', 'nan', 'nan'] APOGEE data list, mjd=59492, all raw_data: /data/apogee/utr_cdr/59492/apRaw-*.fits archive: /data/apogee/archive/59492/apR-[a,b,c]-*.apz quickred: /data/apogee/quickred/59492/ap2D-a-*.fits.fz ------------------------------------------------------------------------------ mjd i UT File/Exp Imtype Nread A/B Dth Ct-Plate Arch Offset %Flux Comm ------------------------------------------------------------------------------ 59492 1 23:54 39300001 Dark 3 A 13.0 ------- a-b-c -
