APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday February 5, 2003 (MJD 52676) ---=== OBSERVING TEAM ===--- swing: Howard Brewington (APO) night: Scot Kleinmanv (APO) Mike Harvanek (APO) visiting: Rich Kron Atsuko Nitta ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds, humidity, and blowing snow kept us closed all night. The nut on the imager LN2 fill hose is becoming quite rounded and needs to be replaced soon. ---=== OBSERVING LOG ===--- Swing shift: During day shift, I checked the focus of the spectrographs; all four cameras were reported by IDL as out-of-focus. I did a sp1; mechPiston 4215 and a sp2; mechPiston 1755. Afterwards, all cameras were in focus except for b2. So, I adjusted b2 by the amount recommended via IDL, vis., -8.4 degrees. After a third set of Hartmann exposures, IDL reported all cameras as in focus. At the time of these focus procedures, m1's temp= 2.72C. The final col-motor numbers (A to C) were: sp1=1757, 1757, 1757 ; sp2=3636,3636,3636. Night shift: Thick cloud coverage, then humidity, kept us closed for the first part of the night. Things started to clear around 08:00, but conditions were very rapidly changing and clouds, blowing snow, etc., suggested we would not gain much by opening. We continued to await stability. It never came and we never opened, although conditions did calm down around 11:30 - but too late to get much useful before twilight (and the constnant changing conditions and blowing snow earlier made us nervous). ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 3655 20:21Z 20:36Z 100 O 150.11 153.76 38 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 ----- sequence 19168, plate -9999 ------- 20:17 19168 0.0 bias ----- sequence 19169, plate 1210 ------- 22:31 19169 10.0 flat 22:34 19170 2.0 arc 22:59 19171 2.1 arc 23:01 19172 2.1 arc 23:17 19173 2.1 arc 23:19 19174 2.1 arc 23:40 19175 2.1 arc 23:42 19176 2.1 arc ----- sequence 19179, plate 1210 ------- 00:43 19179 0.0 bias ---=== 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 20:33Z 27 25 13 189 (S) 564 - 21:04Z 27 24 22 215 (SW) 1619 - 21:36Z 28 22 14 211 (SSW) 1397 - 22:08Z 29 23 17 215 (SW) 1595 - 22:40Z 28 22 22 211 (SSW) 679 - 23:13Z 28 21 17 235 (SW) 225 - 23:45Z 28 21 21 246 (WSW) 223 - 00:50Z 28 18 25 252 (WSW) 401 - 01:23Z 28 20 10 254 (WSW) 353 - 01:55Z 28 21 26 251 (WSW) 219 - 02:27Z 28 21 23 245 (WSW) 202 - 03:00Z 27 22 23 233 (SW) 167 - 03:32Z 26 24 27 233 (SW) 166 - 04:04Z 26 26 17 237 (WSW) 5545 - 04:36Z 26 26 18 268 (W) 6525 - 05:08Z 26 26 22 270 (W) 6028 - 05:41Z 26 26 22 251 (WSW) 2213 - 06:13Z 25 24 25 240 (WSW) 258 - 06:45Z 24 23 25 249 (WSW) 360 - 07:17Z 21 14 16 262 (W) 390 - 07:50Z 22 10 18 273 (W) 407 - 08:22Z 22 8 19 241 (WSW) 471 - 08:54Z 21 7 20 254 (WSW) 533 - 09:26Z 21 7 12 265 (W) 661 - 09:58Z 20 5 12 334 (NNW) 479 - 10:32Z 19 4 13 327 (NNW) 494 - 11:03Z 19 4 8 321 (NW) 509 - ---=== TELESCOPE STATUS ===--- ---=== 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 0.7970 0.7970 Axial C 0.8180 0.8240 Trans D -9.0740 -9.1130 Lateral E 1.8460 1.8870 Lateral F 0.0000 1.4300 GALILS Commanded: 5400. -3700. 900. -200. 31550. 30650.
