APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday October 17, 2003 (MJD 52930) ---=== OBSERVING TEAM ===--- Mike Harvanek Stephanie Snedden Jurek Krzesinski (swing) Jon Brinkmann (by phone) Jim Annis (by email) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Imaging: 82 S lambda 126 to 140 82 N lambda 162 to 178 Spectroscopy: 4 plates finished (1087, 1250, 1243, 1529) and good data on another one (1127). Problems: Lots of fiducial errors too large to correct the past 2 nights (PR 5711). Flat and arc of one preCal appeared to be combined into one exposure. ---=== OBSERVING LOG ===--- swing shift: ------------ No problems during setup except that collimate on sos failed when IDL called the collimate process. night: ------ Had problems with the az fiducial at 34 deg(errors too large to correct). This delayed the start of imaging until about ten minutes past twilight. We began with 82 S. The 2 degree ramp began at 0155Z, frame 12, lambda 124. Science started at 0202Z, frame 25, lambda 126. We ended this scan at 0301Z, frame 124, lambda 140.8 to go to the higher priority 82 N. 82 N began at 0306Z lambda 159. Ramp began at 0309Z, frame 13, lambda 160. Science started at 0317Z, frame 26, lambda 162. Ended scan 0440Z, frame 165, lambda -177 due to bad seeing. Good seeing ended around frame 136, lambda 178. Moon rises in less than an hour so not enough time for apache wheel. We switch to spectroscopy. Plate 1087 (cartridge 7): No guide stars on the gotoField but once the AZ correction too large to apply was corrected the guide stars appeared. There was a problem during preCals. Neither preCal frame would read out. Steph did an endStare and read out a single frame (22664). What appeared to be a flarc (combination flat and arc) appeared on spectro 1. An arc frame appeared on spectro 2. The flat for spectro 2 was not evident. See the Problems section for the detailed error message. A second attempt at preCals was successful. This plate was finished in 3 exposures (3000 s total). Plate 1250 (cartridge 8): FK5 used to acquire field. When combined with last night's data, this plate was finished in 1 900 s exposure. SoS refused to reduce r1 (both last night and tonight) but Jim Annis looked at last night's data and said we needed only one more exposure with s/n^2 of 3 to finish it. We are calling it done. We have gotten multiple fiducial readings too large to correct (mostly in az but some in alt) the last two nights. It is starting to affect efficiency. Is it just moths or is there some other problem (new PID values, az bearings)? A PR (5711) was filed. Plate 1127 (cartridge 5): FK5 used to acquire field. This plate required a large rotator correction and a large scale change but we were finally able to get all the guide stars centered. This plate expired after 1 900 s exposure. Plate 1243 (cartridge 4): Guide stars on the gotoField. When combined with last night's data, this plate was finished in 1 1200 s exposure. Plate 1529 (cartridge 1): Guide stars on the gotoField. This plate was done in 3 exposures but since there was nothing else to observe at the end of the night we did 2 additional exposures and got bonus s/n (5 exposures, 4500 s total). When stopping the guider on the last exposure, we got the following: SOPGUI: stopGuider Failed to chmod /data/spectro/52930/guider/gimg0993.fits /data/spectro/52930/guider/gimg0993.fits: Operation not permitted A second stopGuider worked fine. There was a nasty alt2 slip as we were stowing the telescope this morning. endNight is still running. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4185 23:52Z 00:11Z 100 O 93.26 98.13 35 ignore 4186 01:21Z 01:37Z 100 O 115.76 119.70 40 bias 4187 01:51Z 03:01Z 82 S 123.28 140.97 132 science 4188 03:05Z 04:41Z 82 N 159.15 -176.75 173 science ---=== IMAGING RUN DETAILS ===--- See the main log. ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- 4187 19 4 137 -2.200 0.149 -2.100 0.131 0.00011 180 57 4187 73 4 89 -2.900 0.145 -1.700 0.370 -0.00060 180 57 4187 120 4 63 -3.600 0.101 -2.100 0.119 -0.00035 180 57 4188 11 4 42 -1.000 0.112 -0.300 0.116 -0.00024 150 53 4188 18 4 44 -0.600 0.163 -0.500 0.127 0.00077 150 53 4188 69 4 44 -0.200 0.161 -0.500 0.113 0.00031 150 53 4188 121 4 47 -1.300 0.214 -0.200 0.160 -0.00028 150 53 ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ 4187 30 1 57 0 76 0.635 0.175 0.320 0.138 -0.00108 4187 30 1 57 0 77 0.962 0.201 0.452 0.116 -0.00152 4187 30 1 57 0 75 1.198 0.170 0.461 0.161 -0.00155 4187 30 1 57 0 83 1.324 0.184 0.485 0.190 -0.00163 4187 30 1 57 0 67 1.551 0.101 0.309 0.242 -0.00104 4187 47 1 57 0 74 -0.300 0.130 0.012 0.167 -0.00004 4187 47 1 57 0 77 -0.035 0.082 0.052 0.174 -0.00017 4187 47 1 57 0 64 0.262 0.097 -0.057 0.171 0.00019 4187 47 1 57 0 53 0.589 0.146 -0.100 0.151 0.00034 4187 47 1 57 0 70 0.844 0.081 -0.044 0.156 0.00015 4187 83 1 57 0 58 -0.312 0.120 -0.315 0.163 0.00106 4187 83 1 57 0 67 0.039 0.170 -0.197 0.138 0.00066 4187 83 1 57 0 63 0.335 0.151 -0.102 0.163 0.00034 4187 83 1 57 0 53 0.586 0.187 -0.139 0.133 0.00047 4187 83 1 57 0 47 0.689 0.202 -0.143 0.105 0.00048 4187 101 1 57 0 48 -0.150 0.200 -0.104 0.136 0.00035 4187 101 1 57 0 42 0.093 0.149 -0.139 0.230 0.00047 4187 101 1 57 0 44 0.546 0.122 0.130 0.227 -0.00044 4187 101 1 57 0 27 0.624 0.170 0.042 0.202 -0.00014 4187 101 1 57 0 49 0.889 0.151 -0.013 0.166 0.00004 4188 131 1 53 30 12 1.293 0.421 1.416 0.353 -0.00476 4188 131 1 53 30 12 0.899 0.289 1.126 0.319 -0.00379 4188 131 1 53 30 17 0.911 0.442 1.263 0.330 -0.00425 4188 131 1 53 30 17 0.430 0.366 1.361 0.277 -0.00458 4188 131 1 53 30 14 0.309 0.395 1.399 0.277 -0.00470 4188 149 1 53 30 8 1.864 0.297 0.781 0.193 -0.00263 4188 149 1 53 30 9 1.788 0.258 0.796 0.164 -0.00268 4188 149 1 53 30 9 1.919 0.424 0.698 0.177 -0.00235 4188 149 1 53 30 5 0.943 0.290 1.050 0.247 -0.00353 4188 149 1 53 30 9 1.159 0.333 0.802 0.244 -0.00270 ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): YES QA Procedures Done (y/n): YES UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 23:59 22660 2.1 arc test 00:02 22661 2.1 arc test ----- sequence 22662, plate -9999 ------- 00:37 22662 0.0 bias 05:02 22663 0.0 bias ----- sequence 22664, plate 1087 ------- 05:35 22664 2.1 arc bad - see log 05:39 22665 10.0 flat 05:41 22666 2.0 arc 06:01 22667 900.1 target 20.9 16.5 18.8 13.8 DONE 06:19 22668 900.1 target 06:43 22669 1200.1 target 06:46 22670 10.0 flat 06:48 22671 2.0 arc ----- sequence 22672, plate 1250 ------- 07:09 22672 10.0 flat 5.4 ????
