APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday May 5, 2003 (MJD 52765) ---=== OBSERVING TEAM ===--- Swing: Pete Newman Night: Jurek Krzesinski, Howard Brewington ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Although we had some clouds around midnight, we declared six plates done, vis., 1277, 1224, 1311, 1317, 1293, and 1338. ---=== OBSERVING LOG ===--- Swing shift notes: ----------------- Spectrographs focus checked and adjusted (see section at end of log). Night shift notes: ___________________ QA procedures completed. Because of moonlight, we started with spectro. Around midnight, we had some clouds that slowed our progress on a couple of cartridges. Plate 1277, (cartridge #2), guide stars after go to field. Plate declared done in three exposures. Plate 1224, (cartridge #3), guide stars after go to field. Plate declared done in three exposures. Plate 1311, (cartridge #5), guide stars after go to field. Plate declared done in three exposures. Plate 1317, (cartridge #6), guide stars after go to field. Plate declared done in three exposures. Plate 1293, (cartridge #9), guide stars after go to field. Plate declared done in four exposures. Plate 1338, (cartridge #7), guide stars after go to field. Plate declared done in three exposures. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 3932 23:28Z 00:08Z 100 O -75.24 -65.24 59 ignore 3933 00:10Z 00:27Z 100 O -64.90 -60.57 42 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): y QA Procedures Done (y/n): y Bias 20817 checked - ok.
