APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday February 7, 2003 (MJD 52678) ---=== OBSERVING TEAM ===--- Scot Kleinman Jurek the flying Krzesinski Mike Harvanek - honorary swingshifter ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds, snow, humidity, fog- never opened. It was clear when I got up today, snowing when I went to sleep. ---=== OBSERVING LOG ===--- We had no swing shifter today, but managed to reboot 'host and take care of other afternoon activities ourselves and with help from Mike Harvanek. The afternoon collimate check showed r1 and r2 in focus, but b1 and b2 not. It suggested an ~-20 degree rotation (0.55 pixel) for b1, almost equal and opposite to the ~16deg rotation we did last night. b2 requested a 9.1 degree rotation (-0.26 pixels off). Questioning this, we did a preCalib, which reduced fine with no wsigma warnings. We ran goSpecFocus two additional times. The second and third times produced very similar recommendations as did the first effort: 1st 2nd 3rd b1 0.55px, -19.7deg 0.56; -20.1 0.59; -24.1 b2 -0.26px, +9.1deg -0.24; 8.6 -0.23; 8.2 r1 -0.09px -0.12 -0.11 r2 0.13px 0.11 0.08 Despite the repeatability, given past indications that we are chasing noise, and the successful preCalib wsigma, we elected to make no collimation change. Thick clouds prevented opening at the start of the night, then humidity and snow and fog. We never opened- endNight ran successfully. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 3659 23:27Z 00:06Z 100 O -161.20 -151.59 78 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 ===--- UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 00:00 19217 2.1 arc 00:02 19218 2.1 arc 00:13 19219 2.1 arc 00:15 19220 2.1 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== 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 ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:58Z 31 21 5 242 (WSW) 257 - 00:29Z 26 21 7 272 (W) 258 - 01:02Z 25 22 6 281 (W) 213 - 01:34Z 25 23 6 306 (NW) 250 - 02:06Z 24 23 7 264 (W) 221 - 02:38Z 24 23 6 264 (W) 235 - 03:10Z 25 23 7 263 (W) 248 - 03:43Z 24 23 2 231 (SW) 210 - 04:15Z 24 24 7 227 (SW) 7941 - 04:47Z 23 23 8 233 (SW) 10536 - 05:19Z 22 21 8 212 (SSW) 301 - 05:51Z 23 22 6 182 (S) 15482 - 06:24Z 23 22 5 184 (S) 4036 - 06:56Z 23 22 5 212 (SSW) 248 - 07:28Z 24 23 6 255 (WSW) 5775 - 08:00Z 23 22 7 217 (SW) 22177 - 08:33Z 23 21 8 201 (SSW) 5270 - 09:05Z 23 21 6 184 (S) 13340 - 09:37Z 23 21 8 228 (SW) 9291 - 10:09Z 23 21 11 217 (SW) 5310 - 10:41Z 23 21 7 218 (SW) 12781 - ---=== TELESCOPE STATUS ===--- never opened or turned on fans ---=== SOFTWARE USED ===--- IOP/SOP: v3_105_0 Watcher: v2_20_0 MCP: v5_17_0 TPM: tpm_v2_24_0 AstroDa: v14_47 TCC: TCC 2.6.8 November 13 2002 sdssProcedures: v1_62 SoS: v4_9_13 hoggPT: v1_5_8 plate-mapper: v4_2_0 ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A 0.0830 0.0790 Axial B 0.7960 0.7970 Axial C 0.8030 0.8240 Trans D -9.0880 -9.1130 Lateral E 1.8560 1.8870 Lateral F 0.0000 1.4300 GALILS Commanded: -2350. -11450. -6800. -200. 31550. 30650.
