APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday July 20, 2005 (MJD 53572) ---=== OBSERVING TEAM ===--- Steph Snedden ---=== OBSERVING PLAN ===--- Imager calibration ---=== OBSERVING SUMMARY ===--- g2 and g3 linearity measurements taken. Dan, you'll need to finish compressing and scp'ing tonight's data to 'commish to be sure you have enough disk space for tomorrow's measurements...unless I do it during the day from home. Dewar 1 odd-even banding was seen at the end of the night while doing a regular bias drift. The t-bars had been moved back to "doghouse" just prior to the bias. ---=== OBSERVING LOG ===--- Imager calibrations: Imager cals failed during the initial bias stare with a backplane communications problem with ad2, and the inability to pull frames from the pool. After the backplane error message, I got the following: Waiting for command response from ad2 (crate 3, ICC 1), data server (client 1) Waiting for command response from ad2 (crate 3, ICC 1), data server (client 1) Waiting for command response from ad2 (crate 3, ICC 1), data server (client 1) Sigh. Blow the DA's nose and start over. That wasted a good half hour or more. Run 5460 - g2 linearity.

Tonight's data are still on sdsshost in /data/photo/doi/calibdata. Either Dan or I will move them to sdsscommish tomorrow. 09:00Z Note: After running a regular bias after shutting down the MSP, I saw odd/even banding in dewar one. I saved frame 17 for the dewar 1 CCDs in /usrdevel/snedden/53572. I also emailed Jim and Connie. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5457 02:06Z 02:20Z 100 O 39.69 43.18 37 ignore 5459 03:57Z 04:03Z 100 O 67.47 69.12 25 ignore 5462 08:48Z 09:04Z 100 O 140.42 144.48 40 ignore ---=== 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 ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL Stays: JL ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 01:29Z 67 42 17 77 (ENE) 871 - 02:02Z 65 41 14 71 (ENE) 948 - 02:34Z 63 41 15 78 (ENE) 840 - 03:06Z 63 41 17 79 (E) 834 - 03:38Z 61 41 17 80 (E) 668 - 04:11Z 60 41 20 86 (E) 491 - 04:44Z 59 42 19 78 (ENE) 399 - 05:16Z 58 44 16 85 (E) 402 - 05:49Z 57 46 17 74 (ENE) 481 - 06:21Z 56 47 20 84 (E) 533 - 06:53Z 56 46 17 68 (ENE) 567 - 07:25Z 58 43 20 69 (ENE) 448 - 07:57Z 58 41 17 73 (ENE) 480 - 08:30Z 60 38 15 75 (ENE) 449 - 09:02Z 60 35 9 78 (ENE) 437 - ---=== TELESCOPE STATUS ===--- ---=== SOFTWARE USED ===--- IOP/SOP: v3_149_0 Watcher: v2_30_0 MCP: v5_26_0 TPM: tpm_v2_47_0 AstroDa: v14_47 TCC: TCC 2.7.2.1 August 6 2004 sdssProcedures: v2_03 SoS: v4_10_7 hoggPT: v1_6_9 plate-mapper: v4_3_1 ---=== MIRROR NUMBERS ===--- ---=== PROBLEMS IN DETAIL ===---
