APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday October 17, 2007 (MJD 54391) ---=== OBSERVING TEAM ===--- Audrey Simmons (swing) Shannon Watters Observer Howard Brewington Observer ---=== OBSERVING PLAN ===--- SEGUE & Supernova Science! ---=== OBSERVING SUMMARY ===--- We were closed for the first part of the night because of high winds and dust. Later in the night, however, we were able to image 82 S lambda -172.7 to -123, which included ramps. The LN2 auto-fill hose for spectro one has a problem. There's a snap ring on the connector, which is not in the proper place. ---=== OBSERVING LOG ===--- Afternoon: ---------- Thank you for the more disk space!!! Set spectrographs for 5.5C. Did not start ventiliating because of high wind and dust. Night: ------ 00:25Z We had high winds and dust at sunset, so we waited for better conditions. Dust was 10K with wind gusts at about 40MPH. 04:49Z Dust at 15K with winds at ~35MPH. 06:51Z Dust at 1.7K with winds at 39.7 mph. However, we opened the doors/louvers and turned on the fans. We also forced filled the spectro dewars in case we get to open soon. 07:52Z Weather conditions are improving, so we mounted the imager and did an on-telescoope bias with Run #7073. 08:10Z Enclosure off, checked top/bottom balance, did test slew to check fiducial crossings. We did not open the DIMM because of the high wind conditions. 08:30Z Run # 7074 goDrift 82 S -startLambda -174.0 Frame 22 start ramp at -172.7, skipy happy, focus converged. Frame 35 start science at -170.7 seeing=~3" Frame 340 end science 11:50Z Frame 353 end ramp 12:05Z Enclosure on and dismounted imager 12:25Z endNight finished and was happy. Misc Watcher messages are posted in the Problems Section. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7072 22:08Z 22:22Z 100 O 67.16 70.85 39 ignore 7073 07:53Z 08:11Z 100 O -146.14 -141.55 45 bias 7074 08:28Z 11:55Z 82 S -174.82 -122.77 362 science ---=== IMAGING RUN DETAILS ===--- Run 7073: On-telescope bias in darkened enclosure. +++++++++++++++++++++++++++++++ Run #7074 82 S -startLambda -174.0 Frame Lambda Notes ----- ------ -------------------------------------------------------- 22 -172.7 start ramp, skippy happy, focus converged 35 -170.7 start science 340 -125.0 end science 353 -123.0 end ramp ++++++++++++++++++++++++ ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- 7074 18 4 54 -5.600 0.175 3.700 0.172 -0.01189 235 42 7074 69 4 57 -6.700 0.200 2.700 0.195 -0.01164 235 42 7074 121 4 38 -6.800 0.203 2.700 0.176 -0.01142 235 42 7074 174 4 9 -6.300 0.163 2.500 0.124 -0.00880 235 42 7074 226 4 16 -6.800 0.173 2.400 0.198 -0.01095 235 42 7074 279 4 61 -6.900 0.192 1.700 0.163 -0.01257 235 42 7074 329 4 43 -6.500 0.213 1.300 0.151 -0.01167 235 42 ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ 7074 80 1 42 305 3 -2.881 0.123 1.212 0.211 -0.00407 7074 80 1 42 305 5 -2.412 0.355 2.295 0.316 -0.00772 7074 80 1 42 305 7 -2.388 0.171 1.324 0.301 -0.00445 7074 80 1 42 305 5 -1.823 0.285 1.503 0.457 -0.00505 7074 80 1 42 305 7 -1.451 0.497 1.595 0.307 -0.00536 7074 98 1 42 305 11 -2.512 0.372 1.638 0.212 -0.00551 7074 98 1 42 305 16 -2.205 0.424 1.367 0.579 -0.00460 7074 98 1 42 305 7 -1.630 0.376 1.602 0.361 -0.00539 7074 98 1 42 305 4 -1.396 0.469 1.105 0.178 -0.00371 7074 98 1 42 305 9 -0.999 0.330 1.533 0.272 -0.00515 7074 253 1 42 305 16 -1.652 0.206 1.275 0.249 -0.00429 7074 253 1 42 305 4 -1.388 0.079 1.145 0.305 -0.00385 7074 253 1 42 305 8 -0.696 0.268 1.611 0.510 -0.00542 7074 253 1 42 305 8 -0.125 0.224 2.101 0.347 -0.00706 7074 253 1 42 305 5 0.055 0.252 2.112 0.231 -0.00710 7074 288 1 42 305 5 -1.507 0.111 0.554 0.344 -0.00186 7074 288 1 42 305 14 -0.873 0.214 1.545 0.381 -0.00519 7074 288 1 42 305 13 -0.884 0.316 1.099 0.463 -0.00369 7074 288 1 42 305 7 -0.078 0.111 1.900 0.220 -0.00639 7074 288 1 42 305 10 0.282 0.489 2.109 0.421 -0.00709 7074 306 1 42 305 13 -1.467 0.191 2.197 0.472 -0.00739 7074 306 1 42 305 9 -1.102 0.164 2.509 0.168 -0.00843 7074 306 1 42 305 19 -0.654 0.228 2.394 0.259 -0.00805 7074 306 1 42 305 10 -0.348 0.341 2.645 0.167 -0.00889 7074 306 1 42 305 13 0.220 0.335 2.885 0.264 -0.00970 7074 340 1 42 305 5 -2.366 0.200 0.593 0.508 -0.00199 7074 340 1 42 305 8 -1.844 0.359 1.006 0.436 -0.00338 7074 340 1 42 305 6 -1.373 0.269 1.157 0.353 -0.00389 7074 340 1 42 305 6 -0.736 0.350 1.644 0.335 -0.00553 7074 340 1 42 305 3 -0.453 0.345 1.871 0.549 -0.00629 ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): y QA Procedures Done (y/n): y IDL 5.5a> apo_plotbias, 46780 Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00046780.fit -5.3 -4.1 -2.0 2.4 7.9 9.5 11.2 sdR-b2-00046780.fit -7.8 -5.7 -4.4 1.9 6.9 9.4 11.8 sdR-r1-00046780.fit -6.7 -4.6 -3.5 2.0 7.8 9.6 11.8 sdR-r2-00046780.fit -7.1 -5.7 -4.0 1.7 8.0 10.1 12.8 Done for 79.217322 sec. % Program caused arithmetic error: Floating underflow % Program caused arithmetic error: Floating illegal operand IDL 5.5a> UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 46780, plate -9999 ------- 22:10 46780 0.0 bias ----- sequence 46781, plate 2821 ------- 22:20 46781 10.0 flat 22:23 46782 2.0 arc 22:29 46783 3.0 arc 22:31 46784 3.0 arc 22:49 46785 2.0 arc 22:51 46786 3.0 arc ----- sequence 46787, plate 0 ------- 23:13 46787 0.0 bias ----- sequence 46788, plate -9999 ------- 23:32 46788 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 22:53Z 2 0 1.00000 0 -241 -236 121 30.1 8.3 31 255 10:08Z imager 1.00000 0 -337 -281 -55 41.9 2.3 14 325 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 20:52Z 47 23 32 241 (WSW) 4320 -
