APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday February 20, 2008 (MJD 54517) ---=== OBSERVING TEAM ===--- Howard Brewington (swing) Dan Long (support) Jon Brinkmann (support) ---=== OBSERVING PLAN ===--- Pre-shake! ---=== OBSERVING SUMMARY ===--- I completed many pre-shake items; see log: ---=== OBSERVING LOG ===--- Fiducial Tables: ---------------- I built and installed new fiducial tables (v1_70) for each axis. When I did test slews, however, the rot axis had large errors, which "accept a new fiducial" would not correct. I talked with Dan, and he thought that there could be a problem with my new table for the rot axis although the table and its plots looked normal. He suggested that I try the previous rot table (v1_69) as a test. I did, and the rot axis behaved normally again. I explained to Dan that I had not planned to install a new rot table and only did so because of the fiducial read-head work recently done on the telescope. Dan said that the rot read_head had not been moved. So, I decided to leave the old rot table (v1_69) in place. Consequently, we currently have a new alt.dat and az.dat table but are using the old rot table. I will do more investigation about the reason my new rot.dat table produced problems. Spectro Monthly Checkout: -------------------------- Cart 01 was mounted for these tests below. XMIN and XMAX were okay; see below: b1 r1 b2 r2 XMAX 0.1 -1.0 -2.6 6.4 XMAX 2030 2048 2117 2094 WAVEMIN and WAVEMAX were also okay; see below: b1 r1 b2 r2 WAVEMIN 3804 5763 3800 5796 WAVEMAX 6172 9213 6171 9233 Checked and adjusted spectro focus; it's set to ~4 degree C at present. I looked at some of the bias, flat, and arc images; all was well. The guideCam was also tested; it worked. Home and Relax Procedure ------------------------ The home and relax procedure was completed on M1 and M2. PT ------ After starting a mop session, the PT had a comm (back plane) problem. Its crate needed to be rebooted. The PT was not tested beyond bias and flat tests because of clouds. The PT FF-lamp has NOT been replaced for this darkrun. sdssHost2: uptime ------------------ [hjbrew@sdsshost2 hjbrew]$ uptime 20:50:41 up 5:20, 26 users, load average: 0.53, 0.41, 0.34 [hjbrew@sdsshost2 hjbrew]$ ---=== 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): y QA Procedures Done (y/n): y UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 50196, plate -9999 ------- 02:51 50196 0.0 bias ----- sequence 50197, plate 2151 ------- 03:13 50197 10.0 flat 03:15 50198 2.0 arc 03:27 50199 3.0 arc 03:29 50200 3.0 arc 03:51 50201 10.0 flat 03:54 50202 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== 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 00:41Z 37 15 16 249 (WSW) 857 - 01:17Z 36 17 15 262 (W) 984 - 01:49Z 35 17 14 256 (WSW) 1007 - 02:21Z 36 17 11 265 (W) 960 - 02:53Z 35 18 15 272 (W) 824 - 03:24Z 34 19 17 295 (WNW) 732 - 03:54Z 33 21 14 295 (WNW) 665 - 04:25Z 32 23 10 287 (WNW) 686 - 04:58Z 32 23 10 300 (WNW) 660 - 05:28Z 32 23 11 263 (W) 727 - 05:58Z 32 23 13 266 (W) 709 - 06:30Z 31 23 11 262 (W) 640 - ---=== TELESCOPE STATUS ===--- Doors and louvers closed; fans off.
