APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday July 4, 2007 (MJD 54286) ---=== OBSERVING TEAM ===--- Kaike Pan Dan Oravetz ---=== OBSERVING PLAN ===--- Try to finish plate 2464 ---=== OBSERVING SUMMARY ===--- The plan is to finish SEGUE faint plate 2464, otherwise, we will lose all signals that we collected during last dark run. But the weather did not cooperating. We never open due to overcast sky. ---=== OBSERVING LOG ===--- afternoon: --------- Spectrographs focus adjusted for ~ 15C. Night: ------ Tonight is officially engineering time. French is very kind to keep the telescope funtionable. So we might have the last chance to save signals on plate 2464 (SEGUE faint). The plan is to finish SEGUE faint plate 2464, otherwise, we will lose all signals that we collected during last dark run. But the weather did not cooperating. We never open due to overcast sky. 05:20Z we decided to quit because the sky will not clearup soon according to satellite images, and the plate will expire in two hours. 05:25Z endNight finished. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- ---=== 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 45592, plate -9999 ------- 01:28 45592 0.0 bias 01:32 45594 0.0 bias 01:35 45595 0.0 bias ----- sequence 45596, plate 2464 ------- 01:44 45596 10.0 flat 01:46 45597 2.0 arc 01:56 45598 3.0 arc 01:59 45599 3.0 arc 02:15 45600 3.0 arc 02:18 45601 3.0 arc 02:30 45602 10.0 flat 02:32 45603 2.0 arc 03:15 45604 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 01:39Z 5 2464 1.00000 0 1257 0 121 30.0 15.2 21 74 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 00:14Z 62 47 15 89 (E) 708 - 00:46Z 60 47 18 79 (E) 698 - 01:18Z 60 47 21 74 (ENE) 712 - 01:50Z 59 49 21 78 (ENE) 738 - 02:23Z 58 49 18 75 (ENE) 858 - 02:53Z 58 49 24 73 (ENE) 823 - 03:23Z 53 49 11 346 (NNW) 4306 - 03:54Z 53 48 9 338 (NNW) 2659 - 04:27Z 51 49 13 13 (NNE) 2371 - 04:59Z 50 49 10 10 (N) 1506 - ---=== TELESCOPE STATUS ===--- ---=== SOFTWARE USED ===--- IOP/SOP: v4_35_0 Watcher: v2_36_0 MCP: v6_4_0 TPM: tpm_v3_5_0 AstroDa: v15_13_1 TCC: TCC 2.7.2.1 August 6 2004 sdssProcedures: SoS: v5_1_8 plate-mapper: v4_3_1 ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A 0.0060 -0.0050 Axial B 0.0150 0.0090 Axial C 0.0130 0.0160 Trans D 0.0030 0.0040 Lateral E 9.9568 9.9568 Lateral F 11.5316 11.5443 GALILS Commanded: 4600. -2000. 2650. -9300. -9800. -9800.
