APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday December 20, 2001 (MJD 52264) ---=== OBSERVING TEAM ===--- Steph Snedden Scot Kleinman Atsuko Nitta (day) Visiting Russell Owen (UW) Visiting Pete and Jurek ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Never photometric, but we plodded through a few plates in the clouds. We done declared 3 plates and got partial work on a couple others. Had 2 additional examples of the TCC<->MCP miscommunication, one of which is detailed in the log and in the Problems section. ---=== OBSERVING LOG ===--- During opening, slewing the telescope up from the 6degrees opening position, it aborted at ~19:45 altitude. It took two axis inits to put things right. First up: cartridge 4, plate 739. The first az fiducial crossing on our first gotoField was too large to correct, but was fine on the next one (~00:52UT). We did not find any guideStars, but an fk5InFiber easily revealed a star we could center up on. As last night, the secondary MIGs moved fine during scaleChanges. Clouds and poor seeing quickly made all our efforts useless. We switched the timetracker to clouds at 02:02UT. When this plate set, we decided to waste some more time and mounted cartridge 3, plate 803. Here again, an fk5InFiber was needed (clouds or pointing?). We took our time in mounting due to the bad weather, so don't penalize us, Jurek!:> We got a couple good exposures before clouds took us out again. We patiently awaited the next sucker hole and managed to finish this plate off. The smear was taken in possibly cloudy conditions. Next up: cartridge 1, plate 760. We found stars on the initial gotoField, this time. It took more than a few long exposures, but we finished this plate, too and went on to cartridge 8, plate 569. We found 4 stars on the gotoField and set a world record for instChange time at 2:47. It took a couple extra axis inits to get the telescope happy after this lightning quick instrument change. See details in Problems. We didn't need any additional scaleChange for this plate. Lots of clouds here, but we eeked out a few good scientific photons. We finished this plate in only 7 exposures, then mounted cartridge 7, plate 555. Once again, we needed multiple axis inits to regain telescope control after the instChange. We also had an az error too large to correct during the slew. We forced the correction (it repeated across multiple fiducials and was about -2000 ticks), but still could not find our fk5 star! A longer exposure revealed the elusive bright star and we were able to continue. But, the gotoField revealed no stars. Clouds were still present and twilight was approaching (time 12:12UT), so we decided to stick around and search. spiralPattern found the star ~15"E. Clouds (and twilight) moved in quickly during the end of this exposure ---=== IMAGING RUN SUMMARY ===--- Run Stripe Flavor Lambda Last Begin End Frame Comments ------------------------------------------------------------------ ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot --------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields nGood rowMean rowSig colMean colSig rot --------------------------------------------------------------- ---=== SPECTROSCOPY DATA SUMMARY ===--- UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 23:21 12324 0.0 bias ----- sequence 12325, plate 739 ------- 01:07 12325 10.0 flat 01:10 12326 2.0 arc 01:38 12327 1201.0 target 02:01 12328 1200.0 target ----- sequence 12329, plate 803 ------- 03:16 12329 10.0 flat 03:18 12330 2.0 arc 03:45 12331 1201.0 target 04:08 12332 1200.0 target 04:30 12333 1201.0 target 05:10 12334 902.0 target 05:16 12335 240.0 smear 05:19 12336 10.0 flat 05:21 12337 2.0 arc ----- sequence 12338, plate 760 ------- 05:31 12338 10.0 flat 05:33 12339 2.0 arc 06:12 12340 1502.0 target 06:35 12341 1200.0 target 06:57 12342 1201.0 target 07:26 12343 1502.0 target 07:33 12344 240.0 smear 07:56 12345 1201.0 target 07:59 12346 10.0 flat 08:01 12347 2.0 arc ----- sequence 12348, plate 569 ------- 08:11 12348 10.0 flat 08:14 12349 2.0 arc 09:00 12350 1025.0 target 09:32 12351 1200.0 target 09:54 12352 1200.0 target 10:17 12353 1200.0 target 10:45 12354 1502.0 target 11:13 12355 1501.0 target 11:20 12356 240.0 smear 11:43 12357 1200.0 target 11:45 12358 10.0 flat 11:47 12359 2.0 arc ----- sequence 12360, plate 555 ------- 12:20 12360 10.0 flat 12:22 12361 2.0 arc 12:41 12362 901.0 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument getclock Az Alt Rot Scale ------------------------------------------------------------------------------ 18:22 4 739 1008897754 0.002854 0.003289 -0.008071 0.999800 20:34 3 803 1008905656 0.004510 0.000734 0.003757 0.999980 22:46 1 760 1008913619 0.005710 0.001623 -0.008340 1.000110 02:31 8 569 1008927078 0.007654 0.000727 -0.003695 1.000070 05:25 7 555 1008937552 0.002015 0.002959 0.000000 1.000150 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL Stays: JL ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 18:23 4 739 0.99980 1974 2810 25 -55 60.6 4.2 16 160 gdr 2.1" 20:34 3 803 0.99998 198 1127 -200 18 55.8 3.4 7 200 gdr 1.9" 22:51 1 760 1.00011 -1085 215 -75 116 47.6 2.9 12 174 gdr 2.5" 02:31 8 569 1.00007 -690 488 -100 32 56.9 2.9 19 207 gdr 1.9" 05:26 7 555 1.00015 -1480 -200 -125 213 60.3 3.5 23 210 gdr 1.35" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 15:55 43 3 5 188 (S) 168 - 16:28 41 0 13 155 (SSE) 115 - 17:00 39 -6 19 148 (SSE) 87 - 17:30 39 -13 20 149 (SSE) 130 - 18:03 39 -18 18 153 (SSE) 212 - 18:35 40 -14 16 158 (SSE) 232 - 19:05 41 -4 13 174 (S) 169 - 19:36 40 -1 3 175 (S) 179 - 20:08 39 3 9 179 (S) 191 - 20:39 40 2 14 184 (S) 156 - 21:10 42 0 12 188 (S) 82 - 21:41 43 -2 14 197 (SSW) 149 - 22:14 40 3 11 180 (S) 201 - 22:46 37 10 12 179 (S) 280 - 23:19 37 11 5 151 (SSE) 292 - 23:51 35 11 8 185 (S) 285 - 00:23 39 10 16 189 (S) 204 - 00:55 38 15 12 199 (SSW) 313 - 01:27 37 16 11 185 (S) 344 - 02:00 37 16 20 194 (SSW) 345 - 02:31 37 17 19 206 (SSW) 400 - 03:03 38 18 24 205 (SSW) 397 - 03:36 38 15 21 211 (SSW) 344 - 04:08 38 17 20 212 (SSW) 402 - 04:41 39 15 16 210 (SSW) 291 - 05:14 39 16 20 208 (SSW) 336 - 05:46 39 15 22 217 (SW) 247 - ---=== TELESCOPE STATUS ===--- Fans on; Doors cracked: 23:00UT Open: 00:15UT Closed: ~13:00UT - cart 8 left on telescope Building interlocks bypassed Slip detection (az and alt) bypassed East door safety bump switch bypassed ---=== SOFTWARE USED ===--- IOP/SOP: v3_64_3a Watcher: v2_13_2 MCP: v5_8_5 TPM: v2_4_5 AstroDa: v14_40 TCC: 2.5.5 sdssProcedures: v1_34 tccMon: v1_7 ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A 0.0730 0.0750 Axial B 0.8040 0.8020 Axial C 0.0750 0.0710 Trans D -1.4990 -1.4860 Lateral E 1.8550 1.8540 Lateral F 1.4180 1.4240 GALILS Commanded: 5400. -3700. 900. -200. 31550. 30650.
