APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday October 18, 2005 (MJD 53662) ---=== OBSERVING TEAM ===--- Howard Brewington ---=== OBSERVING PLAN ===--- Pre-darkrun checkout ---=== OBSERVING SUMMARY ===--- ---=== OBSERVING LOG ===--- Completed the home/relax procedure for M1 and M2. In spite of mig communication faults as reported by Watcher (see problems section), the mirror numbers look good. Mike and I took a look at the PT to see if the Dec noise, while slewing, was gone. During the first slew, we heard the noise but was unable to repeat the problem with additional slews. We think the noise could be coming from the LN2 hoses sliding through the connector on the fork. If so, this is not a problem. I will try to repeat the problem again tomorrow. I noticed that the humidity sensor a the 2.5-meter telescope is reading about 50% as compared to the 3.5-meter. I also noticed that the bellows pressure on the SDSS camera is reading about 45 when normal is 40. Is this a problem? ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- ---=== 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ---=== 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 03:06Z 50 47 14 205 (SSW) -9999 - 03:38Z 50 48 13 208 (SSW) -9999 - 04:10Z 48 49 19 212 (SSW) -9999 - 04:42Z 48 48 22 214 (SW) -9999 - 05:14Z 48 48 19 217 (SW) -9999 - 05:47Z 47 47 22 210 (SSW) -9999 - 06:19Z 46 45 20 209 (SSW) -9999 - ---=== TELESCOPE STATUS ===--- Telescope at 121,30,00 mount LN2 connected and turned on Cart 09 mounted; CWs at 270lbs Imager 138lbs 21psi Spectro 289lbs 23psi ---=== SOFTWARE USED ===--- IOP/SOP: v4_5_0 Watcher: v2_30_2 MCP: v5_26_0 TPM: tpm_v3_1_0 AstroDa: v15_4 TCC: TCC 2.7.2.1 August 6 2004 sdssProcedures: SoS: v4_10_7 hoggPT: v1_6_9 plate-mapper: ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A -5.8410 -5.8440 Axial B -5.6860 -5.6770 Axial C 0.9390 0.9420 Trans D -9.9880 -9.9940 Lateral E 10.3378 10.3759 Lateral F 11.9126 11.9380 GALILS Commanded: 4700. -2450. 3000. -7800. 3300. 3000.
