APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday February 22, 2004 (MJD 53058) ---=== OBSERVING TEAM ===--- night Jurek Krzesinski and Mike Harvanek ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Nothing done, we've got clouds all night. ---=== OBSERVING LOG ===--- Afternoon checkout: ------------------- sp2: collimator A shows a hudge number on mechSend: Coll_motor_A -33528 Coll_motor_B 6833 Coll_motor_C 3821 sp1: seems to be ok: Coll_motor_A 6854 Coll_motor_B 5854 Coll_motor_C 4354 But spectrographs are in focus (see the problem section for cllimation results). Note: ----- The telescope was parked at 121,30 (az,alt) in the enclosure. We issued a track command to get mirrors collimated (stops buttons were on). Then we saw the follwing message in the marmur: 2004-02-23 00:17:01Z sdssmcp tLatch dsc_I_trcInfo Applying correction 74 to altitude Why that happend? Night: -------- Night lost due to clouds. endNight done on cloudy tapes. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4479 00:11Z 00:27Z 100 O -135.85 -131.77 41 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 25258, plate -9999 ------- 00:00 25258 0.0 bias 00:11 25259 0.0 bias ----- sequence 25260, plate 1461 ------- 00:22 25260 0.0 bias 00:27 25261 10.0 flat 00:30 25262 2.0 arc 00:37 25263 2.1 arc 00:40 25264 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 none Stays: JL none ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 00:08Z 2 1461 1.00000 0 1258 0 121 30.0 1.9 15 240 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:35Z 38 12 21 221 (SW) -9999 - 00:07Z 35 8 15 232 (SW) -9999 - 00:39Z 34 5 14 226 (SW) -9999 - 01:11Z 33 7 11 209 (SSW) -9999 - 01:43Z 32 10 14 220 (SW) -9999 - 02:16Z 32 10 12 233 (SW) -9999 - 02:48Z 32 10 9 215 (SW) -9999 - 03:20Z 31 11 8 239 (WSW) -9999 - 03:52Z 31 11 5 186 (S) -9999 - 04:24Z 32 13 3 231 (SW) -9999 - 04:56Z 31 13 8 245 (WSW) -9999 - 05:29Z 31 14 3 239 (WSW) -9999 - 06:01Z 31 15 9 220 (SW) -9999 - 06:33Z 30 16 11 183 (S) -9999 - 07:05Z 30 17 8 182 (S) -9999 - 07:38Z 30 18 8 183 (S) -9999 - 08:10Z 30 18 11 196 (SSW) -9999 - 08:42Z 30 19 12 217 (SW) -9999 - 09:14Z 29 19 11 206 (SSW) -9999 - 09:46Z 28 20 9 184 (S) -9999 - 10:18Z 28 21 15 196 (SSW) -9999 - 10:51Z 28 23 10 190 (S) -9999 - 11:23Z 28 23 6 197 (SSW) -9999 - ---=== TELESCOPE STATUS ===--- ---=== SOFTWARE USED ===--- IOP/SOP: v3_128_0 Watcher: v2_29_0 MCP: v5_25_0 TPM: tpm_v2_37_0 AstroDa: v14_47 TCC: TCC 2.7.1 July 22 2003 sdssProcedures: v1_84 SoS: v4_10_7 hoggPT: v1_6_9 plate-mapper: v4_3_1 ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A 0.5450 0.5420 Axial B 0.6270 0.6390 Axial C 1.0990 1.0900 Trans D -8.4520 -8.4610 Lateral E 10.8839 10.8966 Lateral F 10.8585 10.8712 GALILS Commanded: 4600. -2850. 850. -9250. 18400. 17850.
