APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday March 2, 2003 (MJD 52701) ---=== OBSERVING TEAM ===--- Scot Kleinman Mike Harvanek Jurek Krzesinski (day) Visitors: David Hogg (NYU) David Schlegel (PU) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We were open for about 20 minutes and managed to finish one plate left over from last run! ---=== OBSERVING LOG ===--- Afternoon checkout: ------------------ DAs -ok, spectro guider -ok, MIGs -ok. Spectrograph focus (at ambient 1.3 C): in focus (focus check results in problem section). Night: ------ Snow and clouds all afternoon cleared up as twilight approached, so we decided to press our luck and try to finish cart 3, plate 1210. GSOTGTF. During the QA checks of the initial biases, we noticed that the left half or the r2 bias is about 600, whereas most every other chip half is ~1200. This is the case over the past several nights (even before French worked on b2), so we suspect it's OK. We got enough clear skies to finish this plate, but it clouded up quickly and proceeded to snow, so we closed (before it started snowing, fyi) and remained so the rest of the night. We watched the humidity, fog, snow and did some site shovelling. The end. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 3692 22:18Z 22:46Z 100 O -156.02 -148.80 62 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): yes QA Procedures Done (y/n): yes UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 19576, plate -9999 ------- 22:18 19576 0.0 bias ----- sequence 19577, plate 1210 ------- 22:35 19577 0.0 bias 23:07 19578 0.0 bias 23:11 19579 10.0 flat 23:14 19580 2.0 arc 23:17 19581 2.1 arc 23:20 19582 2.1 arc ----- sequence 19583, plate -9999 ------- 00:17 19583 0.0 bias ----- sequence 19584, plate 1210 ------- 00:34 19584 0.0 bias 02:01 19585 10.0 flat 02:04 19586 2.0 arc 02:30 19587 1200.1 target 02:45 19588 741.8 target - declared bad ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 01:59Z 3 1210 104.92 0.0021 49.94 -0.0023 -102.72 0.0039 1.000230 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL6022 Stays: JL6029 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 02:10Z 3 1210 1.00021 -2073 -617 -75 104 52.3 -2.5 7 182 gdr 1.8 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:12Z 30 18 14 202 (SSW) 263 - 22:44Z 28 20 12 182 (S) 293 - 23:16Z 27 18 9 176 (S) 408 - 23:49Z 28 18 7 200 (SSW) 298 - 00:19Z 28 20 8 234 (SW) 331 - 00:51Z 29 20 1 247 (WSW) 431 - 01:24Z 26 18 1 200 (SSW) 434 - 01:54Z 27 18 6 186 (S) 376 - 02:26Z 28 16 3 186 (S) 412 - 02:58Z 27 20 6 109 (ESE) 430 - 03:30Z 25 22 0 304 (NW) 450 - 04:02Z 24 22 3 333 (NNW) 356 - 04:34Z 24 21 5 68 (ENE) 390 - 05:07Z 25 21 1 212 (SSW) 383 - 05:39Z 24 23 0 227 (SW) 12878 - 06:11Z 24 23 2 273 (W) 4470 - 06:43Z 23 23 7 289 (WNW) 4200 - 07:15Z 23 23 9 262 (W) 1239 - 07:48Z 23 22 2 263 (W) 644 - 08:20Z 23 21 9 318 (NW) 127 - 08:52Z 23 17 7 264 (W) 296 - 09:24Z 22 19 5 273 (W) 236 - 09:56Z 22 19 4 297 (WNW) 3653 - 10:26Z 21 17 6 274 (W) 9793 - Clouds, Humidity, Snow most of the night ---=== TELESCOPE STATUS ===--- No interlocks bypassed 00:50Z doors cracked and fans on 01:15Z We opened the enclosure 02:45Z Clouds and snow: closed enclosure - fans off Cart 3 mounted on telescope ---=== SOFTWARE USED ===--- IOP/SOP: v3_109_3 Watcher: v2_21_0 MCP: v5_18_0 TPM: tpm_v2_27_0 AstroDa: v14_47 TCC: TCC 2.6.8 November 13 2002 sdssProcedures: v1_64 SoS: v4_9_13 hoggPT: v1_6_2 plate-mapper: v4_2_0 ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A 0.0910 0.0790 Axial B 0.7930 0.7970 Axial C 0.8140 0.8240 Trans D -9.0820 -9.1130 Lateral E 1.8820 1.8870 Lateral F 0.0000 1.4300 GALILS Commanded: 5400. -3700. 900. -200. 31550. 30650.
