Subject: 2.5m obslog 20210816 (SJD 59443) From: kinemuchi@apo.nmsu.edu Date: Tue, 17 Aug 2021 10:02:04 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday August 16, 2021 (SJD 59443) ---- Observing Team ---- Dylan Gatlin Karen Kinemuchi ---- Observing Plan ---- Pointing model ---- Observing Summary ---- Entire night lost to weather. Adjusted the APOGEE flat lamps. See summary for results. ---- Observing Log ---- Afternoon: Engineering camera alive and homed. The rotator roller was heat treated and installed. I did some test slews from -30 to 180 and the fiducial errors were very small (<20) The podium STUI is an old version and has some old scripts in it. As per John Wilson's instructions, we rotated the apogee cal box brass knurling knob 3 rotations counter clockwise and started evening cals. Did not ventilate due to weather. NIGHT: ====== APOGEE evening cals finished, but there seems to be some strange errors. See APOGEE data summary section for more information. 02:33Z Adjusting the system and taking another quartz flat. We took a series of Quartz flats, and compiled the table below. For the brass knob, the positive direction is defined as counterclockwise, and corresponds with increased flux. Flux taken via a large circle in DS9 around the middle chip. Elena's list_ap script also analyzes flux relative to a standard quartz flat, so those values are also reported here.

The knob is very nonlinear and the closer you get to optimal levels, the more precise you must be. There are some marks on the top of the knob, but it's hard to be precise. The total move was 0.7 +/- 0.2. The flux is higher than it was this spring, but based on Elena's percentage, it should be closer to the flux of the master flat, whenever that was taken. If further adjustment is needed, try to do it in increments of at most 0.25 turns. 03:31Z arc lamps were already at 10 mA, no adjustments were made. 06:11Z Humidity has dropped, but lots of nearby radar and lightning. We remain closed. 09:58Z Giving up. ---- Mirror Numbers ---- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A: 0.0120 0.0070 Axial B: 0.0330 0.0290 Axial C: -0.1230 -0.1220 Trans D: -0.0421 -0.0421 Lateral E: 0.3315 0.3310 Lateral F: 0.5340 0.5340 GALILS Commanded: 12500 -1600 5300 47050 -8800 -8400 Actual: 12500 -1600 5300 47050 -8800 -8400 SETMIR VALUES PrimDesOrient: 0.0 -31.23 -9.35 -511.08 1708.0 PrimOrient: 0.0 -31.15 -9.21 -511.43 1706.53 SECONDARY: ---------- Focus: 0.0000 Air temp: 12.61 Altitude: 30.00027229011306 MIGS TONIGHT NOMINAL Axial A: -9.4480 -9.4600 Axial B: -9.4710 -9.4780 Axial C: -9.5030 -9.5050 Trans D: 0.1050 0.0980 GALILS Commanded: 4630900 4625900 4644250 -50 -3450 Actual: 4607199 4607262 4607256 -50 -3450 SETMIR VALUES SecDesOrient: 3657.0 0.0 0.0 0.0 42.22 SecOrient: 3656.99 -0.01 0.02 0.01 42.69 ---- Telescope Status ---- Never opened. ---- Software Used ---- -- STUI software: STUI : 1.7.13 alerts : trunk apo : trunk boss : unknown -boss.specMec : Offline gcamera : v2_2 guider : unknown hartmann : 1.8.0 hub : Tag: v4.2 mcp : 2.0-7-g8799 -mcp.plc : 34 -mcp.azFiduci : v1_146 -mcp.altFiduc : v1_146 -mcp.rotFiduc : v1_146 platedb : 2.8.0 sop : 4.0.8 tcc : 1.4.0 apogee : not availble apogeecal : not availble apogeeql : unknown STUIAdditions : 3.1.7 -- done -- -- Other versions ---- idlspec2d : v5_7_12 plate-mapper3 : NOCVS:v7_0_9 petunia : 2.2.3 autoscheduler : git sdss_python_module: trunk mangadrp : trunk exported ---- APOGEE Data Summary ---- APOGEE data list, mjd=59443, all raw_data: /data/apogee/utr_cdr/59443/apRaw-*.fits archive: /data/apogee/archive/59443/apR-[a,b,c]-*.apz quickred: /data/apogee/quickred/59443/ap2D-a-*.fits.fz -------------------------------------------------------------------------------- mjd i UT File/Exp Imtype Nread A/B Dth Ct-Plate Arch Offset %Flux Comm -------------------------------------------------------------------------------- 59443 1 00:05 38810001 Dark 3 A 13.0 19- 0 a-b-c - - 59443 2 01:21 38810002 Dark 60 A 13.0 19- 0 a-b-c - - 59443 3 01:32 38810003 QuarFlat 10 A 13.0 19- 0 a-b-c - 1616 59443 4 01:34 38810004 Arc-Thar 12 A 13.0 19- 0 a-b-c err - 59443 5 01:36 38810005 Arc-Thar 12 A 13.0 19- 0 a-b-c 12.38 - 59443 6 01:38 38810006 Arc-Une 40 A 13.0 19- 0 a-b-c - - 59443 7 01:45 38810007 Arc-Une 40 A 13.0 19- 0 a-b-c - - 59443 8 01:52 38810008 Dark 60 A 13.0 19- 0 a-b-c - - 59443 9 02:22 38810009 QuarFlat 10 A 13.0 19- 0 a-b-c - 1270 59443 10 02:30 38810010 QuarFlat 10 A 13.0 19- 0 a-b-c - 716 59443 11 02:40 38810011 QuarFlat 10 A 13.0 19- 0 a-b-c - 29 59443 12 02:52 38810012 QuarFlat 10 A 13.0 19- 0 a-b-c - 229 59443 13 03:00 38810013 QuarFlat 10 A 13.0 19- 0 a-b-c - 91 59443 14 03:32 38810014 Dark 60 A 13.0 19- 0 a-b-c - - 59443 15 03:42 38810015 QuarFlat 10 A 13.0 19- 0 a-b-c - 92 59443 16 03:44 38810016 Arc-Thar 12 A 13.0 19- 0 a-b-c 11.60 - 59443 17 03:46 38810017 Arc-Thar 12 A 13.0 19- 0 a-b-c 11.27 - 59443 18 03:49 38810018 Arc-Une 40 A 13.0 19- 0 a-b-c - - 59443 19 03:56 38810019 Arc-Une 40 A 13.0 19- 0 a-b-c - - 59443 20 04:03 38810020 Dark 60 A 13.0 19- 0 a-b-c - - --------------------------------------------------------------------------------
