APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday April 1, 2003 (MJD 52731) ---=== OBSERVING TEAM ===--- Swing: Atsuko Kleinman Night: Mike Harvanek Dan Long Dining Support: Scot Kleinman Steph Snedden Jack Dembicky Bill Ketzeback John Barentine Craig Loomis Jackie Diehl Jon Davis ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Five plates completed (1214, 995, 1288, 1232, 1198) in variable cloud conditions. ---=== OBSERVING LOG ===--- Afternoon ----------- 00:00Z We saw some thin streaks of clouds and changed to spectro. Night -------- 02:02Z Cartridge 1 1214 15.2 15.3 20.6 15.9 Guide stars on slew. Done in three. 03:40Z Cartridge 2 995 17.5 14.2 19.1 15.3 Guide stars on slew West latch didn't register open on first and second try when removing cartridge 1. Lowered then raised lift a bit. All three latches showed open on third try. Does something on cartridge 1 need adjusting? Lots of cloud trouble. Took 5 exposures. 20149 got S/N between 1.7-2.0 06:22Z Cartridge 9 1288 19.4 20.7 20.9 21.4 Needed FK5 due to clouds Clouds leave early in first exposure Decidedly done in three 07:35:42Z InstChange 07:38:59Z gotoField 07:39Z Cartridge 3 1232 19.5 16.9 20.1 18.8 Needed FK5 due to pointing Done in three 08:54Z Cartridge 5 1198 8.6 8.0 8.0 5.4 Guide stars on the slew One exposure finished this one. Clouds stopped all observing for over an hour. It cleared with less than half an hour before twilight so we took the smear and postCals for this plate and called it a night. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 3843 23:41Z 00:00Z 100 O -105.59 -100.87 46 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): Yes QA Procedures Done (y/n): No, spent too much time eating, sorry.
