Subject: 2.5m obslog 20080703 (MJD 54651) Date: Fri, 4 Jul 2008 04:55:02 -0600 (MDT) From: snedden@apo.nmsu.edu (Steph Snedden) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday July 3, 2008 (MJD 54651) ---=== OBSERVING TEAM ===--- Viktor Malanushenko Steph Snedden ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- -More clouds and high humidity for much of the night. -Imager calibrations: linearity g1 - g3 done - teamster process hung up during MSP calibrations (see log body). - Obtained useful signal on SEGUE faint plate 2320 ---=== OBSERVING LOG ===--- Afternoon: ---------- No problems during afternoon checkout. - No disk space cleared - Adjusted sp1's focus by 1000 (see end of log) - Cartridge 3 mounted - Prepared for imager calibrations Night: ----- 02:19Z - Skies were mostly cloudy. lightning was getting closer and humidity and dust were rising. We prepared for g linearity imager calibrations and waited for twilight to deepen. 03:25Z Run 7597 g1 linearity ---------------------------- 03:30 first frame, idR-7597-g1-2.fit 04:35 last frame , idR-7597-g1-20.fit 04:45Z - Run 7599 g2 linearity ------------------------------ A few frames into this sequence, there was a teamster problem that caused Viktor's MSP IOP session to freeze up. The offending teamster had to be killed by its PID number before a new one could be started. For good measure, we also cleared the pool, even though test.tcl is supposed to do that. An attempt to take an exposure then gave archiver errors, and we ended up rebooting the crates. Viktor started a new IOP, took a regular bias drift to make sure the DA was happy, then restarted the g2 linearity. So please ignore run 7597 frames 21 - 25. 05:57 MSP bias , run 7599 frame 1 06:02 first frame idR-7599-g2-2.fit 07:09 last frame idR-7599-g2-21.fit 07:12Z - Run 7599 g3 linearity ------------------------------- 07:13 first frame idR-7599-g3-22.fit 08:10 last frame idR-7599-g3-40.fit The photodiode noise was within tolerance for all tests. Details at the end of the log 08:24 bias drift, run 7600 The sky had mostly cleared and the humidity finally dropped. We opened for SEGUE spectroscopy. 08:46Z - Cartridge 6, plate 2320 - SEGUE faint ---------------------------------------------- GSOGTF Took two exposures totaling 3000 s. (S/N)^2 = 21.8, 12.8, 24.5, 16.7 A third exposure was started, then aborted when the humidity went to closure conditions. endNight complained that there were missing gangs from run 7598 - the bias drift that we ran after the crate reboot. The gangs did not transfer over when the teamster was restarted, so they appear to be gone for good. Other than that, endNight finished okay. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7598 05:50Z 05:54Z 100 O 79.23 80.20 21 bias 7600 08:23Z 08:42Z 100 O 117.77 122.34 44 bias ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 53905, plate 2813 ------- 00:00 53905 10.0 flat 00:03 53906 2.0 arc 00:15 53907 2.0 arc 00:17 53908 3.0 arc 00:30 53909 10.0 flat 00:32 53910 2.0 arc 00:41 53911 0.0 bias ----- sequence 53912, plate 2320 ------- 08:54 53912 10.0 flat 08:57 53913 2.0 arc 09:26 53914 1500.0 target second and third target exposures missing - logTool died and was restarted, and the enties are missing. ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 09:07Z 6 2320 10.58 0.0017 49.58 0.0052 188.89 0.0115 1.000500 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 09:07Z 6 2320 1.00050 -4938 -2730 175 11 49.6 11.0 20 77 -- 1.5 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:53Z 62 42 3 93 (E) 2075 - mostly cloudy 00:23Z 62 42 13 69 (ENE) 2193 - ' 00:53Z 62 42 7 100 (E) 2218 - ' 01:24Z 60 46 10 80 (E) 2967 - ' 01:54Z 58 46 4 86 (E) 3311 - ' 02:26Z 57 48 4 125 (SE) 3528 - ' 02:56Z 56 48 3 103 (ESE) 3810 - ' 03:26Z 55 48 6 90 (E) 3875 - ' 03:56Z 55 50 7 101 (E) 4285 - ' 04:26Z 54 50 5 96 (E) 4585 - ' 04:56Z 53 49 14 121 (ESE) 3720 - ' 05:27Z 52 50 9 111 (ESE) 4509 - partly cloudy 05:57Z 53 50 17 78 (ENE) 4285 - ' 06:28Z 52 50 9 83 (E) 4096 - ' 06:59Z 52 49 12 89 (E) 4075 - ' 07:30Z 52 43 12 80 (E) 1785 - ' 08:01Z 53 39 14 85 (E) 1195 - ' 08:32Z 53 39 14 81 (E) 1038 - ' 09:02Z 51 40 19 81 (E) 1265 - mostly clear 10:43Z 51 45 0 147 (SSE) 2726 - ---=== TELESCOPE STATUS ===--- 08:30Z Started ventilation 08:30Z Opened enclosure 09:18Z Closed enclosure.
