Date: Mon, 4 Oct 2004 05:40:23 GMT From: prn@apo.nmsu.edu (Pete Newman) Subject: 2.5m obslog 20041003 (MJD 53282) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday October 3, 2004 (MJD 53282) ---=== OBSERVING TEAM ===--- Swing: Pete Newman Support: Wendell Jordan, Scot Kleinman (by phone) ---=== OBSERVING PLAN ===--- Pre-shake check list items. ---=== OBSERVING SUMMARY ===--- Done: o PT check-out completed o Spectrographs monthly checks completed o Disk space cleared o Engineering camera mounted. Not done: o Build new fiducial tables o Home/relax mirrors o New PT flat-field lamp o Software building (if needed, see shakedown plan) The M2 MIG positions are out of tolerance: see Mirrors section for comments. ---=== OBSERVING LOG ===--- Pre-shake evening. Low clouds and marginal humidity, so the enclosure was not ventilated. An item new to me: on the south fork, there is a Jib Crane Lockout. It is set to "Yep" with the key in (does that key come out?). o TPM recurrent errors noted in the Problems section. o DA tape drives cleaned. o sdsshost rebooted (over 5 days since last reboot) o Imager found to be alive (doghouse bias). During a doghouse bias, ID4 reported a rimfire failure almost immediately. See problems section for details. This was quickly traced to a write-protect tab in the wrong position. During telescope moves to mount a spectrograph cartridge, Watcher caught an error: SecDesMountOutOfRange="FFFTF":: (2004-10-03 21:02:11Z) At this time, TCC inst=imager, focus= -224.40, scale=1. Instrument set to spectro, focus=0 at alt=30. Error did not recur. Spectro monthly checks ====================== Cartridge 4, plate 1917 mounted. Camera temperatures, LN2 status all within tolerance. Initial collimator motor positions: sp1: Coll_motor_A -3892 Coll_motor_B -2926 Coll_motor_C -4599 sp2: Coll_motor_A -5476 Coll_motor_B -5724 Coll_motor_C -5974 This is being checked at 15:25 MDT. Enclosure temperatures: im> caget tpm_TM_PMSSAvg tpm_TM_TelairAvg.VALA tpm_TM_PMSSAvg 13.2486 tpm_TM_TelairAvg.VALA 13.225 o Check Xmin/Xmax positions: frame 28694, all positions within tolerance. o Check Wmin/Wmax positions: frame 28695, all positions within tolerance. o Focus and collimation checks: note this adjustment is being made for the purpose of spectro check-out, not night-time temperature adjustment, so it may be necessary to re-focus again during shake. Note also these were adjusted with rot=0 not rot=45. sp1> goSpecFocus IDL> collimate, 28696 COLLIMATE: Mean offset = -0.11 pix COLLIMATE: Camera b1 appears to be IN-FOCUS (|mean| 0.15 pix) COLLIMATE: Predict blue camera ring movement of -11.6 degrees for spectro-2 COLLIMATE: Mean offset = -0.18 pix COLLIMATE: Camera r1 appears to be OUT-OF-FOCUS (|mean| > 0.15 pix) COLLIMATE: Predict (red) piston movement of 1614 steps for spectro-1 COLLIMATE: Mean offset = -0.34 pix COLLIMATE: Camera r2 appears to be OUT-OF-FOCUS (|mean| > 0.15 pix) COLLIMATE: Predict (red) piston movement of 3130 steps for spectro-2 Issue: sp1> mechPiston 1614 sp2> mechPiston 3130 sp1> goSpecFocus IDL> collimate, 28698 COLLIMATE: Mean offset = -0.25 pix COLLIMATE: Camera b1 appears to be OUT-OF-FOCUS (|mean| > 0.15 pix) COLLIMATE: Predict blue camera ring movement of 8.8 degrees for spectro-1 COLLIMATE: Mean offset = 0.06 pix COLLIMATE: Camera b2 appears to be IN-FOCUS (|mean| goSpecFocus IDL> collimate, 28700 COLLIMATE: Mean offset = -0.06 pix COLLIMATE: Camera b1 appears to be IN-FOCUS (|mean| < 0.15 pix) COLLIMATE: Predict blue camera ring movement of 2.2 degrees for spectro-1 COLLIMATE: Mean offset = 0.04 pix COLLIMATE: Camera b2 appears to be IN-FOCUS (|mean| < 0.15 pix) COLLIMATE: Predict blue camera ring movement of -1.3 degrees for spectro-2 COLLIMATE: Mean offset = -0.04 pix COLLIMATE: Camera r1 appears to be IN-FOCUS (|mean| < 0.15 pix) COLLIMATE: Predict (red) piston movement of 396 steps for spectro-1 COLLIMATE: Mean offset = -0.12 pix COLLIMATE: Camera r2 appears to be IN-FOCUS (|mean| < 0.15 pix) COLLIMATE: Predict (red) piston movement of 1103 steps for spectro-2 Final collimator positions: sp1: Coll_motor_A -2284 Coll_motor_B -1312 Coll_motor_C -2986 sp2: Coll_motor_A -2350 Coll_motor_B -2584 Coll_motor_C -2844 o Dithered flats: frames 28702/28710.

Sample images were examined and no anomalies noticed. SoS reported no errors. apo_plotbias was used on frame 28715. The histogram and plot were put in the Spectro Monthly Checkout folder.

The spectrograph secondary dewars were force-filled around 21:00 MDT. We believe the 108lb in the 180L dewar will suffice for the rest of the night until the day crew arrive (thanks, Wendell, for coming in to check!) but John Barentine is on site and will keep an eye on it. ---=== SOFTWARE USED ===--- IOP/SOP: v3_141_0 (test) Watcher: v2_29_0 MCP: v5_25_0 TPM: tpm_v2_42_0 AstroDa: v14_47 TCC: TCC 2.7.2.1 August 6 2004 sdssProcedures: v1_94 SoS: v4_10_7 hoggPT: v1_6_9 plate-mapper: v4_3_1 ---=== MIRROR NUMBERS ===--- Note: M2 axial B and tranverse D MIG readins are out of tolerance, but these were probably disturbed in the M2 Galil actuator work this bright time.
