APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday August 26, 2003 (MJD 52878) ---=== OBSERVING TEAM ===--- Steph Snedden Scot Kleinman ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We finished one partially done plate (lowz) and watched the weather a lot. ---=== OBSERVING LOG ===--- Humidity finally let us open around 05:30Z. Still some clouds, so we started with spectroscopy: cart 6, plate 1037 (lowz). No GSOTGTF, but an fk5 star was easily found and centered. We finished this plate and went on to: Cart 8, plate 1104 (merged). GSOTGTF. We got preCalibs then the clouds and humidity came in in force and we were forced to stop and ultimately close before starting an exposure. At least we won't need the preCals next time we mount this cart. (Yes, I am joking.) While closing, we had an alt1 slip (around 07:30 or so, probably). The alt drive surfaces were covered with moth guts despite Steph's thorough cleaning at the start of the night. We did not reopen. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4081 22:40Z 22:57Z 100 O 24.00 28.31 39 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 ----- sequence 22101, plate -9999 ------- 22:42 22101 0.0 bias 22:49 22102 0.0 bias ----- sequence 22103, plate 1471 ------- 23:26 22103 10.0 flat 23:28 22104 2.0 arc 23:32 22105 2.1 arc 23:34 22106 2.1 arc 23:45 22107 2.1 arc 23:47 22108 2.1 arc ----- sequence 22109, plate 1037 ------- 05:51 22109 10.0 flat 05:53 22110 2.0 arc 06:12 22111 900.1 target 06:30 22112 900.1 target 06:44 22113 600.1 target 06:47 22114 10.0 flat 06:49 22115 2.0 arc ----- sequence 22116, plate 1104 ------- 07:04 22116 10.0 flat 07:06 22117 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 05:57Z imager 35.25 0.0040 51.71 -0.0008 208.95 0.0076 0.999900 ---=== 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 ------------------------------------------------------------------------------ 05:57Z 6-1037 0.99990 986 1843 -150 35 51.7 12.7 12 111 gdr 1.5" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:15Z 59 47 12 106 (ESE) 112 - 22:48Z 61 47 3 117 (ESE) 136 - 23:20Z 61 47 13 150 (SSE) 176 - 23:51Z 59 48 9 172 (S) 147 - 01:28Z 57 48 6 95 (E) 128 - 02:00Z 56 49 12 107 (ESE) 285 - 02:32Z 55 49 14 117 (ESE) 234 - 03:02Z 54 50 13 116 (ESE) 239 - 03:32Z 54 49 13 109 (ESE) 238 - 04:02Z 54 49 10 110 (ESE) 282 - 04:32Z 54 49 12 112 (ESE) 262 - 05:10Z 55 48 8 110 (ESE) 204 - 05:40Z 55 48 6 105 (ESE) 181 - 06:10Z 55 47 7 96 (E) 174 - 06:40Z 57 47 0 147 (SSE) 194 - 07:11Z 54 48 7 145 (SE) 245 - 07:42Z 53 49 8 166 (SSE) 279 - 08:13Z 53 49 5 162 (SSE) 258 - 08:44Z 52 49 9 166 (SSE) 304 - 09:14Z 52 49 3 184 (S) 358 - 09:46Z 51 49 4 203 (SSW) 357 - 10:16Z 52 50 1 231 (SW) 448 - ---=== TELESCOPE STATUS ===--- Doors cracked; fans on: ~01:00Z closed: 02:45Z (humidity) reopened: ~05:30Z reclosed: ~07:50Z ---=== SOFTWARE USED ===--- IOP/SOP: v3_119_0 Watcher: v2_24_0 MCP: v5_20_0 TPM: tpm_v2_30_0 AstroDa: v14_47 TCC: TCC 2.7.1 July 22 2003 sdssProcedures: v1_73 SoS: v4_9_13 hoggPT: v1_6_9 plate-mapper: v4_3_1 ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A 0.0960 0.0790 Axial B 0.8180 0.7970 Axial C 0.8280 0.8240 Trans D -9.1040 -9.0560 Lateral E 1.8460 1.8870 Lateral F 0.0000 1.4300 GALILS Commanded: 5400. -3700. 900. -200. 31550. 30650.
