APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday July 4, 2008 (MJD 54652) ---=== OBSERVING TEAM ===--- Audrey Simmons Kaike Pan Dan Oravetz (swing) Jon Brinkman (support) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We accumulated signals on plates 2901, 2935, 2320. But none of them was done. We did imager caliberation, g4 linerity. The nitrogen gas bottle by the windscreen knife switch is running very low, it's need to replaced. We accumulated about 15 K-hours with humidity between 73-85%, dew point depression, 3 - 5C. Please check the mirror. ---=== OBSERVING LOG ===--- Afternoon: ---------- All systems checked and working properly. sdsshost2.apo.nmsu.edu % df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 134G 902M 100% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 643G 228G 74% /data sdssfiles1:/data1/data 1.5T 653G 740G 47% /files When I checked the fiducial crossings, the 45-degree altitude fiducial was not read during the slew from 121,30,00 to 121,90,00. It did register during the slew from 121,90,00 to 121,30,00. Spectro focus still set for ~14C (sp1) and ~12C (sp2). No adjustments made. Cartridge 3 is mounted. 01:55Z - Began ventilation. Doors and louvers opened, fans on. Night: ------ Just about 02:20Z we noticed the weather station was down, Jon was called. He found that APOTS1 computer was not responding, he let Audrey power cycled the computer. This fix the problem. 02:30Z enclosure off. 03:10Z cart 3, plate 2901 (segue). SOGTF. Since this plate expires 1 hour ago, we started the first exposure 20 min before twilight ends. We had three exposures on this plate with a total integration time of 4200 s. S/N^2 of b1 is 10.7. 05:00Z cart 9, plate 2935 (segue faint). SOGTF. We had two 25 min exposures on this plate, got S/N^2 of 12.9 on r1. 06:20Z close for high humidity. 07:10Z: Setup for imager calibration, linearity on g4. 07:23Z - MSP bias, run #7602, frame 1 07:25Z - Linearity test on g4, run #7602, frames 2-20. No error message during the data taking, and avoltsRMS are within the tolerance (0.023 v). 08:40Z enclosure off. 08:50Z cart 6, plate 2320 (segue faint). SOGTF. Three 25 min and one 30 min exposures were obtained on this plate. The S/N^2 of 31.6 on r1 was min among 4 cameras. 11:00Z endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7601 00:19Z 00:51Z 100 O -2.69 5.40 67 ignore 7603 08:36Z 08:37Z 100 O 121.85 122.19 16 ignore 7604 08:55Z 09:15Z 100 O 126.55 131.72 49 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 UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 53917, plate -9999 ------- 00:20 53917 0.0 bias ----- sequence 53918, plate 2901 ------- 00:52 53918 10.0 flat 00:54 53919 2.0 arc 00:57 53920 3.0 arc 01:00 53921 3.0 arc ----- sequence 53922, plate -9999 ------- 01:26 53922 0.0 bias 01:33 53923 0.0 bias ----- sequence 53924, plate 2901 ------- 10.7 xx 28.3 (?) 9.1 03:26 53924 10.0 flat 03:29 53925 2.0 arc 03:52 53926 1201.0 target 04:15 53927 1201.0 target 04:48 53928 1802.0 target 04:51 53929 10.0 flat 04:54 53930 2.0 arc ----- sequence 53931, plate 2935 ------- 22.5 12.9 30.1 19.7 05:08 53931 10.0 flat 05:10 53932 2.0 arc 05:41 53933 1501.0 target 06:09 53934 1500.0 target 06:16 53935 10.0 flat 06:19 53936 2.0 arc ----- sequence 53937, plate 2320 ------- 09:04 53937 10.0 flat 09:07 53938 2.0 arc 09:36 53939 1501.0 target 10:04 53940 1501.0 target 10:37 53941 1800.0 target 10:40 53942 10.0 flat 10:42 53943 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 03:31Z 3 2901 -49.59 0.0002 45.19 0.0037 140.17 0.0185 1.000260 05:16Z 9 2935 262.98 0.0003 64.39 0.0032 99.57 0.0278 1.000270 09:11Z 6 2320 7.69 0.0010 49.83 0.0048 186.45 0.0127 1.000340 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 01:30Z 3 0 1.00000 0 1257 0 121 30.0 15.9 13 82 03:31Z 3 2901 1.00026 -2568 -954 -25 -49 45.3 13.1 16 112 -- 1.2 05:16Z 9 2935 1.00027 -2666 -1165 -100 263 64.3 12.4 13 91 -- 1.2 09:11Z 6 2320 1.00034 -3358 -1683 -85 8 49.8 15.0 3 277 -- 1.2 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 00:02Z 65 50 1 254 (WSW) 2794 - mostly clear 00:33Z 61 45 0 174 (S) 2407 - mostly clear 01:03Z 61 44 8 71 (ENE) 2386 - mostly clear 01:34Z 60 44 14 83 (E) 2226 - clear 02:59Z 56 45 -9999 -9999 (N) 2252 - 03:30Z 55 48 15 109 (ESE) 2726 - 04:02Z 55 48 14 91 (E) 2878 - 04:32Z 55 48 16 109 (ESE) 2743 - 05:02Z 54 48 10 84 (E) 2641 - 05:33Z 54 47 13 78 (ENE) 2684 - 06:04Z 53 47 9 78 (ENE) 2630 - 06:35Z 52 48 15 72 (ENE) 2702 - 07:07Z 52 48 11 81 (E) 2542 - 07:39Z 53 48 6 80 (E) 2580 - 08:11Z 53 45 10 47 (NE) 2411 - 08:44Z 55 40 12 4 (N) 2441 - 09:16Z 58 32 0 259 (W) 1862 - 09:48Z 56 34 6 88 (E) 2016 - 10:20Z 56 36 8 83 (E) 2082 - 10:51Z 55 36 8 81 (E) 2200 - clear ---=== TELESCOPE STATUS ===--- 01:55Z - Began ventilation.
