Subject: 2.5m obslog 20160828 (SJD 57629) From: dmbiz@apo.nmsu.edu Date: Mon, 29 Aug 2016 10:56:03 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday August 28, 2016 (SJD 57629) ---- Observing Team ---- Audrey Oravetz Dmitry Bizyaev Kaike Pan ---- Observing Summary ---- The night started as cloudy, but then we were able to open and go on sky. Closed early because of raising humidity. Tasks done: Mirror numbers are collected and declared as current. Performed MANGA plain sky exposures, see details in the log. We completed optical collimation. *** Notes: The offset we had to apply to bring stars to the center of eng. camera is about 3 arcminutes, which sounds very big. We are not sure if it can be compensated by correct fiducials data. Persistent error about ALT interlock in the Interlock menu. See Problems section. Bright LEDs were naked on and around sp1 faced towards the plug lab. Taped some of them with a black tape. More need to be checked. DoS did not reduce biases and darks. Sent a message to Brian. Then we noticed it was fixed. Request to the day staff: please clean telescope drive surfaces that fiducial data can be collected. If you have time and favorable conditions, please take fiducial numbers. Otherwise, night crew will try to get them. ---- Observing Plan ---- Sun 28 AUG 2016 57629.0 0.14 02:44 11:26 18:11 02:56 ---- MaNGA until 06:39 ( 3.9 h), then eBOSS ( 4.8 h) In reality, we need to complete the optical collimation, collect fiducial data, and do a pointing model. ---- Observing Log ---- Afternoon: ========== Checked actors, gathered guider dark, mirror numbers, BOSS cals, and APOGEE cals.

First, spectrographs are not focused (original instruction doesn't require this), and also there are no flats and arcs taken for them. So we first took an arc and a flat at that position: 12 03:49 b1-00225961 5 8069 fla Out C 25.1 26407 26140 22613 13 03:53 b1-00225962 5 8069 arc Out C 4.1 26407 26140 22613 then moved telescope to a less crowded field and took the same plain sky with all calibration around (Hartmanns, arc, and flat) 16 03:59 b1-00225965 5 8069 arc Lef C 4.1 30849 30581 27054 HART 17 04:01 b1-00225966 5 8069 arc Rig C 4.1 30849 30581 27054 HART 04:02:56 Hartmann collimate output on cart #5 sp1: offset: r= 1319 (Out of focus); b= 5.8 (Out of focus) sp2: offset: r= -1577 (Out of focus); b= -5.1 (Out of focus) sp1: pred. move: spAverageMove= -272 sp2: pred. move: spAverageMove= 31 sp1: pred. resid: r= 1591, b= 5.0, txt= Move blue ring 10.0 degrees., spTemp = 12.3 sp2: pred. resid: r= -1608, b= -5.0, txt= Move blue ring -10.1 degrees., spTemp = 11.9 Sorry, it was not ideally focused, with +/- 5 deg tolerance, but since clouds are going to come soon, we proceeded with science exposure (on the plain sky).

The best focus of the eng. camera if found at ~200. Guider images 371,372,373. The pointing was way off. We found stars in the field, but was not sure that one of them is an FK5. So we moved to Vega. Found its glow. Then we were able to find a decent star and collimate. One time we experienced a large (~4 arcmin) jump after a small correction (Kaike did it, we witnessed), but then we were unable to reproduce it and everything worked as expected. We got rather uniform donuts for the optical collimation. 08:01Z Humidity got too high, we had to close. We considered to collect fiducial data, but noticed, that all driving surfaces are affected by moths. Since the day crew has much better experience in surfaces cleaning, we would like to postpone the fiducial data collection until the cleaning. 10:52Z humidity was not improved. We called it a night. Calibrations started. ---- Telescope Status ---- 01:09Z Started ventilation 02:59Z encl25m : open 08:01Z encl25m : closed No interlocks bypassed Status at: Telescope stowed at: 121.0, 30.0, 0.0 mount Instrument mounted: cartridge = eng. camera Counterweights at: 337 LN2 autofill systems: Connected and turned on 180L LN2 dewar scales: SP1 169 lbs, 18 psi SP2 176 lbs, 22 psi ---- Software Used ---- Get Versions, 08/28/16, 23:45:35 -- STUI software: STUI : 1.7.1b4 alerts : trunk+svn66561 apo : trunk+svn158476M boss : v4_0 -boss.specMec : 3.0.4 gcamera : v2_1 guider : v3_4 hartmann : v1_4_3 hub : Tag: sdss4_v3_0 mcp : v6_6_18 -mcp.plc : 34 -mcp.azFiduci : v1_119 -mcp.altFiduc : v1_119 -mcp.rotFiduc : v1_119 platedb : v2_4 sop : v3_8_1 tcc : 1.2.2 apogee : not availble apogeecal : not availble apogeeql : v1_6_1 APO-local : trunk -- done -- Get Versions, 08/28/16, 23:45:35 -- STUI software: STUI : 1.7.1b4 alerts : trunk+svn66561 apo : trunk+svn158476M boss : v4_0 -boss.specMec : 3.0.4 gcamera : v2_1 guider : v3_4 hartmann : v1_4_3 hub : Tag: sdss4_v3_0 mcp : v6_6_18 -mcp.plc : 34 -mcp.azFiduci : v1_119 -mcp.altFiduc : v1_119 -mcp.rotFiduc : v1_119 platedb : v2_4 sop : v3_8_1 tcc : 1.2.2 apogee : not availble apogeecal : not availble apogeeql : v1_6_1 APO-local : trunk -- done -- Setting up: idlspec2d Flavor: Linux64 Version: v5_7_12 Setting up: |elodie Flavor: Linux64 Version: v1_3 Setting up: |spinspect Flavor: Linux64 Version: trunk Setting up: |specflat Flavor: Linux64 Version: v1_20 Setting up: |speclog Flavor: Linux64 Version: trunk Setting up: |platelist Flavor: Linux64 Version: trunk Setting up: |sdss_python_module Flavor: Linux64 Version: v1_6_7 Setting up: |sqlalchemy Flavor: Linux64 Version: 0.9.7 Setting up: |psycopg2 Flavor: Linux64 Version: 2.5.3 Setting up: |idlutils Flavor: Linux64 Version: v5_5_16 Setting up: |idl Flavor: Linux64 Version: 7.1 Setting up: |dust Flavor: Linux64 Version: v0_1 Setting up: |photolog Flavor: Linux64 Version: trunk Setting up: actorcore Flavor: Linux64 Version: v4_0 Setting up: |opscore Flavor: Linux64 Version: v2_4 Setting up: |external Flavor: Linux64 Version: v1_2_0 Setting up: |actorkeys Flavor: Linux64 Version: trunk Setting up: |sdss3tools Flavor: Linux64 Version: v1_7_13 Setting up: |RO Flavor: Linux64 Version: 3.6.9 ---- Mirror Numbers ---- PRIMARY: -------- Scale: 1.000000; MIGS TONIGHT NOMINAL Axial A: 0.865 -0.125 Axial B: 0.24 0.112 Axial C: 0.623 -0.028 Trans D: -0.05 -1.357 Lateral E: 8.9789 10.9728 Lateral F: 14.1224 12.6111 GALILS Commanded: 0 0 0 0 0 0 Actual: 0 0 0 0 0 0 SETMIR VALUES PrimDesOrient: 0.0 0.0 0.0 0.0 0.0 PrimOrient: 344.07 76.73 -69.74 -172.16 -1166.65 SECONDARY: ---------- Focus: 0.0000 Air temp: 12 Altitude: 30.0 MIGS TONIGHT NOMINAL Axial A: -7.186 -0.023 Axial B: -6.678 -0.724 Axial C: -1.306 -0.732 Trans D: -0.168 -0.009 GALILS Commanded: 1626450 1580350 1626900 -8250 -15650 Actual: 1599876 1566484 1586628 -8250 -15650 SETMIR VALUES SecDesOrient: 1257.0 -2.03 -9.35 40.0 278.8 SecOrient: 1257.12 -3.19 -9.83 39.53 279.67 Mirror numbers after home, relax mirrors, and reset Mirror Nominal Migs.
