APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday February 4, 2005 (MJD 53406) ---=== OBSERVING TEAM ===--- Night: John Barentine Mike Harvanek Afternoon helper: Scot Kleinman Guest starring: Steph Snedden ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Bad weather kept us closed all night. We did some snow removal round the site to while away the hours. ---=== OBSERVING LOG ===--- Afternoon --------- Checkout went normally. Focusing the spectrographs took three iterations of goSpecFocus (see Problems section for numbers). Night ----- The weather gods were inadequately propitiated recently, and retaliated with a stalled Pacific low over the Baja that fed us clouds all night. About two inches of snow fell during the night. We never opened. endNight was run on the cloudy night tapes and rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5142 22:50Z 23:07Z 100 O -173.15 -168.91 40 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): n QA Procedures Done (y/n): n UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 30794, plate 2061 ------- 23:59 30794 10.0 flat 00:01 30795 2.0 arc 00:12 30796 2.1 arc 00:14 30797 2.1 arc 00:26 30798 2.1 arc 00:28 30799 2.1 arc 00:42 30800 10.0 flat 00:45 30801 2.0 arc 00:55 30802 2.1 arc 00:58 30803 2.1 arc ----- sequence 30804, plate -9999 ------- 02:35 30804 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 ------------------------------------------------------------------------------ 02:40Z 4 2061 1.00000 0 1258 0 121 30.4 -0.7 17 108 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:52Z 34 25 8 189 (S) -9999 - Overcast 23:22Z 32 23 5 136 (SE) -9999 - Overcast 23:52Z 32 24 14 111 (ESE) -9999 - Overcast 00:25Z 32 26 18 149 (SSE) -9999 - Overcast 00:57Z 31 27 15 127 (SE) -9999 - Overcast 01:29Z 31 27 13 135 (SE) -9999 - Overcast 02:01Z 30 26 18 112 (ESE) -9999 - Overcast 02:34Z 30 26 14 125 (SE) -9999 - Overcast 03:04Z 30 28 30 134 (SE) -9999 - Overcast 03:34Z 26 26 1 143 (SE) -9999 - Overcast 04:04Z 30 28 21 128 (SE) -9999 - Overcast 04:35Z 29 29 24 146 (SE) -9999 - Overcast 05:05Z 29 29 24 151 (SSE) -9999 - Overcast 05:35Z 28 28 26 145 (SE) -9999 - Overcast 06:05Z 27 26 22 127 (SE) -9999 - Overcast 06:35Z 28 28 14 189 (S) -9999 - Overcast 07:05Z 29 29 15 160 (SSE) -9999 - Overcast 07:36Z 29 29 11 204 (SSW) -9999 - Overcast 08:06Z 29 29 22 183 (S) -9999 - Overcast 08:36Z 28 28 14 177 (S) -9999 - Overcast 09:06Z 30 31 11 175 (S) -9999 - Overcast 09:36Z 31 31 7 180 (S) -9999 - Overcast 10:06Z 31 31 12 182 (S) -9999 - Overcast 10:37Z 31 31 7 185 (S) -9999 - Overcast 11:07Z 32 31 15 182 (S) -9999 - Overcast 11:37Z 31 31 11 184 (S) -9999 - Overcast 12:07Z 31 31 13 200 (SSW) -9999 - Overcast ---=== TELESCOPE STATUS ===--- Telescope stowed at 121,30 with Cart 4 (Plate 2061) mounted Counterweights at 160 Spectro autofill reconnected No interlocks bypassed Dewar weights at 12:15Z Imager 206lbs 23psi Spectro 184lbs 26psi ---=== SOFTWARE USED ===--- IOP/SOP: v3_143_0a Watcher: MCP: v5_26_0 TPM: tpm_v2_47_0 AstroDa: v14_47 TCC: 2.7.2.1 sdssProcedures: v1_97 SoS: v4_10_7 hoggPT: v1_6_9 plate-mapper: v4_3_1 ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A 0.5760 0.5790 Axial B 0.5830 0.5880 Axial C 0.9490 0.9460 Trans D -8.2040 -8.1950 Lateral E 10.0457 10.0076 Lateral F 11.6205 11.5824 GALILS Commanded: 4300. -1900. 2850. -13300. -7600. -7650.
