APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday August 14, 2004 (MJD 53232) ---=== OBSERVING TEAM ===--- Mike Harvanek John Barentine ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The imager bias looks a bit odd. Details in the main log. Weather kept us closed all night. ---=== OBSERVING LOG ===--- Afternoon: ---------- The doghouse bias shows a ripple or wave pattern that is visible most notably in g (dewars 2-6) and z (dewars 2, 3, 5, 6). Frame 46 for all chips from doghouse bias 4775 is on sdsshost in /data/photo/bias53232 and on phoenix in /data/photo/bias53232. Perhaps this is related to the imager problem we had last night (53231). Can someone please have a look? Night: ------ High humidity all night. Clouds most of the night. We never opened. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4774 00:41Z 00:51Z 100 O 43.24 45.88 31 ignore waves, ripples in z, g 4775 02:55Z 04:06Z 100 O 76.76 94.55 55 ignore waves, ripples in z, g ---=== 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): Bias checked but nothing else UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 27889, plate 1144 ------- 00:50 27889 10.0 flat 00:52 27890 2.0 arc ----- sequence 27891, plate -9999 ------- 01:03 27891 0.0 bias ----- sequence 27892, plate 1144 ------- 01:07 27892 2.1 arc 01:10 27893 2.1 arc 01:23 27894 2.1 arc 01:26 27895 2.1 arc 02:01 27896 2.1 arc 02:03 27897 2.1 arc 02:15 27898 2.1 arc 02:18 27899 2.1 arc 02:28 27900 2.1 arc 02:30 27901 2.1 arc 02:40 27902 2.1 arc 02:43 27903 2.1 arc 03:20 27904 2.1 arc 03:22 27905 2.1 arc 03:37 27906 2.1 arc 03:40 27907 2.1 arc ---=== 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: none Stays: none ---=== 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 01:16Z 54 46 1 180 (S) 138890 - 01:49Z 50 46 2 90 (E) 163583 - 02:19Z 50 46 4 88 (E) 179566 - 02:50Z 49 46 6 111 (ESE) 194365 - 03:21Z 49 44 10 136 (SE) 185444 - 03:52Z 48 44 14 145 (SE) 188803 - partly cloudy 04:24Z 47 46 12 160 (SSE) 196849 - cloudy 04:56Z 48 45 15 154 (SSE) 189005 - " 05:28Z 48 44 15 134 (SE) 184009 - " 06:01Z 48 45 13 155 (SSE) 185701 - " 06:33Z 48 45 13 145 (SE) 180839 - " 07:05Z 48 44 15 138 (SE) 182131 - " 07:38Z 48 44 13 138 (SE) 172662 - " 08:10Z 48 46 11 154 (SSE) 181306 - " 08:42Z 48 47 10 171 (S) 191059 - " 09:15Z 49 45 7 172 (S) 164258 - " 09:47Z 48 46 3 171 (S) 167677 - " 10:19Z 48 47 7 111 (ESE) 187741 - " ---=== TELESCOPE STATUS ===--- Never opened due to humidity and clouds.
