APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday August 6, 2007 (MJD 54319) ---=== OBSERVING TEAM ===--- Dayshift: Howard Brewington Observers: Steph Snedden Shannon Watters ---=== OBSERVING PLAN ===--- Shakedown, of a preliminary sort... ---=== OBSERVING SUMMARY ===--- The telescope and spectrographs are still not ready for prime time. Weather was typical of the monsoon. After the rains stopped, we had high humidity. We were unable to get any MSP imager linearity data tonight due to hardware problems. ---=== OBSERVING LOG ===--- Afternoon: ----------- Did not find any problems during the checkout. However, I was unable to take any frames with the spectros since French has yet to complete his work with these instruments. I looked in the PT logbook; the FF lamp was replaced on 04 August 07. Night: ---------- Without a working telescope, we planned to use tonight for imager calibrations with Mamoru's spectrophotometer. We planned to start with g5 linearity, however, we encountered four problems during setup. One was that the stageX movement stopped working and we think we may have gone past the limit. We tried hooking up the hand-paddle to manually move the stage back, but could not get any of the keys on the keypad to work (probably just lack of training on our part?). While we were hooking up the hand-paddle, Shannon checked the lamp, and could not see evidence of it coming on, although the lamp connector was very hot and the box the lamp is in was hot. Also, the monochro scanner (wavelength controller) LED for "local" mode comes on, but not the LED for "active" mode, although we were able to change the monochromator wavelength. Finally, the manual stage makes a fairly loud deep buzz when you reach the lower limit. We don't recall ever hearing this before. That's all for tonight, folks. endNight rejoiced. ---=== 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 ---=== 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 ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:33Z 59 54 14 207 (SSW) 446 - cloudy 00:05Z 60 54 10 239 (WSW) 434 - ' 00:37Z 58 54 10 222 (SW) 397 - ' 01:09Z 56 51 7 231 (SW) 227 - ' 01:42Z 54 54 8 306 (NW) 622 - ' 02:26Z 56 52 7 263 (W) 400 - ' 02:58Z 56 52 7 245 (WSW) 369 - ' 03:30Z 54 50 13 120 (ESE) 333 - ' 04:02Z 52 49 15 149 (SSE) 187 - ' 04:34Z 53 48 16 144 (SE) 160 - ' 05:07Z 54 49 10 183 (S) 218 - ' 05:39Z 56 50 9 189 (S) 215 - ' 06:11Z 55 52 7 185 (S) 306 - ' 06:43Z 55 52 6 200 (SSW) 317 - ' 07:15Z 54 51 7 199 (SSW) 255 - ' 07:51Z 53 52 10 218 (SW) 297 - ' ---=== TELESCOPE STATUS ===--- Never Opened ---=== SOFTWARE USED ===--- IOP/SOP: v4_37_0 Watcher: v2_36_0 MCP: v6_4_0 TPM: tpm_v3_5_0 AstroDa: v15_13_1 TCC: TCC 2.9.1 2007-06-21 sdssProcedures: v2_35 SoS: v5_1_8 plate-mapper: v4_3_1 ---=== MIRROR NUMBERS ===--- ---=== PROBLEMS IN DETAIL ===---
