APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday January 5, 2008 (MJD 54471) ---=== OBSERVING TEAM ===--- Viktor Malanushenko (days) Howard Brewington (observer) Steph Snedden (observer) Visitor: Jian Wang (LAMOST) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds, then some science. - Spectro monthly biases and darks were taken. - Finished plate 2863 (SEGUE bright) - Got good signal on plate 2608 (Legacy) ---=== OBSERVING LOG ===--- Afternoon: ---------- All equipment are checked and work properly. Spectro collimation set for +1C. Ventilation is started at 23:15Z. Cart 2 is mounted. Night: ------ The clouds were too thick at sunset to open. 02:45Z - The clouds were hanging around and the humidity was slowly climbing. The building was closed for monthly spectro biases and darks. Bias frames: 48641 - 48665 Dark frames: 48666 - 48668 The quartile results follow: MJD=54471 Date=2008Jan05 Bias, frame 48650 Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00048650.fit -5.7 -4.0 -2.5 1.7 7.0 8.1 10.3 sdR-b2-00048650.fit -8.4 -6.3 -4.7 1.3 7.6 8.9 11.3 sdR-r1-00048650.fit -6.8 -5.4 -3.6 1.6 6.6 8.4 9.6 sdR-r2-00048650.fit -7.7 -6.2 -4.6 1.2 6.4 8.0 9.6 Done for 74.227738 sec. % Program caused arithmetic error: Floating underflow % Program caused arithmetic error: Floating illegal operand IDL 5.5a> apo_plotbias, 48650 Dark, frame 48666 Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00048666.fit -3.1 -0.9 1.1 6.4 12.3 13.7 16.7 sdR-b2-00048666.fit -5.1 -2.6 -0.7 5.5 12.5 14.1 16.6 sdR-r1-00048666.fit -4.7 -3.0 -1.4 4.0 10.6 12.7 14.9 sdR-r2-00048666.fit -5.2 -3.1 -1.7 4.2 10.5 12.6 15.1 Done for 71.529018 sec. % Program caused arithmetic error: Floating underflow % Program caused arithmetic error: Floating illegal operand IDL 5.5a> apo_plotbias, 48666 ----------------------------------------- 04:46Z - wind went over the limit. 10:21Z - A sucker hole appeared. Being suckers, we went for it, and opened. Cartridge 4, plate 2862 - SEGUE bright GSOGTF with old offsets applied. This plate had previous signal. 10:34Z Humidity started to rise... Adding in previous signal, this plate is done, with an 1800s exposure. 11:28Z - Cartridge 6, plate 2608 - Chunk 153 GSOGTF Three good exposures were taken totaling 4200s. Clouds increased during the exposures, so this plate is not quite done. 13:11Z - endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7271 21:46Z 22:13Z 100 O 140.63 147.29 58 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 21:41 48636 0.0 bias ----- sequence 48637, plate 1631 ------- 22:09 48637 10.0 flat 22:11 48638 2.0 arc 22:19 48639 3.0 arc 22:21 48640 2.0 arc ----- sequence 48641, plate 2866 ------- 02:57 48641 0.0 bias monthly biases 02:59 48642 0.0 bias 03:02 48643 0.0 bias 03:04 48644 0.0 bias 03:06 48645 0.0 bias 03:09 48646 0.0 bias 03:11 48647 0.0 bias 03:14 48648 0.0 bias 03:16 48649 0.0 bias 03:18 48650 0.0 bias 03:24 48651 0.0 bias 03:26 48652 0.0 bias 03:28 48653 0.0 bias 03:31 48654 0.0 bias 03:33 48655 0.0 bias 03:36 48656 0.0 bias 03:38 48657 0.0 bias 03:40 48658 0.0 bias 03:43 48659 0.0 bias 03:45 48660 0.0 bias 03:48 48661 0.0 bias 03:50 48662 0.0 bias 03:52 48663 0.0 bias 03:54 48664 0.0 bias 03:57 48665 0.0 bias 04:39 48666 0.0 dark monthly darks 04:58 48667 0.0 dark 05:16 48668 0.0 dark ----- sequence 48669, plate 2862 ------- 10:40 48669 10.0 flat 10:42 48670 2.0 arc 11:17 48671 1803.0 target 4.1 1.0 16.8 1.7 11:20 48672 10.0 flat 11:23 48673 2.0 arc ----- sequence 48674, plate 2608 ------- 11:39 48674 10.0 flat 11:42 48675 2.0 arc 12:06 48676 1201.0 target 6.0 4.5 6.6 4.8 12:34 48677 1501.0 target 3.8 2.8 4.6 2.9 12:57 48678 1201.0 target 3.2 2.5 3.8 2.8 ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 10:50Z 4 2862 21.14 0.0047 55.32 0.0010 197.64 0.0323 0.999920 11:45Z 6 2608 19.34 0.0119 76.31 0.0031 197.19 0.0340 1.000170 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 10:50Z 4 2862 0.99992 790 1994 175 21 55.3 0.4 17 223 -- 2.0 11:45Z 6 2608 1.00017 -1679 -62 205 19 76.3 0.3 22 266 -- 1.5 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 21:04Z 37 26 23 268 (W) 315 - mostly cloudy 21:36Z 38 25 21 256 (WSW) 326 - ' 22:08Z 38 25 14 278 (W) 373 - ' 22:38Z 37 26 21 268 (W) 348 - ' 23:19Z 37 27 15 272 (W) 465 - ' 23:51Z 37 27 17 259 (W) 468 - ' 00:21Z 36 27 15 265 (W) 445 - ' 00:53Z 37 27 21 263 (W) 407 - ' 01:25Z 37 27 26 249 (WSW) 442 - ' 01:57Z 37 28 20 267 (W) 490 - ' 02:29Z 37 28 24 252 (WSW) 438 - ' 03:01Z 37 28 27 233 (SW) 416 - ' 03:33Z 38 28 23 218 (SW) 412 - ' 04:05Z 37 29 24 246 (WSW) 424 - ' 04:38Z 36 28 24 256 (WSW) 456 - ' 05:10Z 37 26 27 268 (W) 440 - ' 05:40Z 36 26 28 253 (WSW) 428 - ' 06:12Z 36 26 26 266 (W) 429 - ' 06:44Z 36 27 25 260 (W) 421 - ' 07:17Z 35 27 22 262 (W) 398 - ' 07:49Z 35 27 24 238 (WSW) 396 - ' 08:21Z 35 26 24 267 (W) 457 - ' 08:53Z 34 26 24 257 (WSW) 412 - ' 09:25Z 34 23 25 264 (W) 381 - ' 09:58Z 33 24 17 259 (W) 450 - ' 10:31Z 33 25 15 261 (W) 414 - partly cloudy 11:03Z 33 25 26 267 (W) 389 - ' 11:35Z 32 26 25 263 (W) 324 - ' 12:07Z 32 26 18 266 (W) 341 - ' 12:40Z 32 26 23 252 (WSW) 350 - ' 13:12Z 32 24 21 246 (WSW) 350 - ' ---=== TELESCOPE STATUS ===--- 23:15Z - Started ventilation, doors opened 10:21Z - Opened enclosure 13:01Z - Closed enclosure, ventilation off Telescope stowed at: 30,121,00 mount Instrument mounted: Cartridge 6 Counterweights at: 270 lbs LN2 autofill systems: Connected and turned on. 180L LN2 dewar scales: Spectro 148 lbs, 17 psi (filling) Imager 193 lbs, 24 psi ---=== SOFTWARE USED ===--- IOP/SOP: v4_38_0 Watcher: v2_36_0 MCP: v6_4_0 TPM: tpm_v3_5_0 AstroDa: v15_13_1 TCC: TCC 2.7.2.1 August 6 2004 sdssProcedures: v2_36 SoS: v5_1_8 plate-mapper: v4_3_1 ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A -5.2140 -5.2160 Axial B -0.2142 -0.2142 Axial C -0.0015 -0.0016 Trans D 11.8460 11.8540 Lateral E 10.0584 10.0584 Lateral F 11.6459 11.6586 GALILS Commanded: 4600. -2000. 2650. -12450. -6500. -6550.
