APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday April 6, 2005 (MJD 53467) ---=== OBSERVING TEAM ===--- Jurek Krzesinski Howard Brewington Mike Harvanek (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Loooong night with variable seeing and clouds conditions, but we got 5 plates done: 2111,2103,2110,1764,1838. No problems to report tonight. We left spectrograph dewars refilling, so they should be good for the day. ---=== OBSERVING LOG ===--- Afternoon: ---------- Spectro collimation adjusted. Details in the Problems section. No problems to report. Night: ------ 02:17Z cart 1 plt 2111. Fk5 used to find the guide stars (too bright). Flat and arc on this plate got bad (r1,r2 XSIGMA red), expnum: 31794. (Mirrors and spectrographs actualy warmed up after opening in regard to the temperature the spectrographs were focused for ~0 C). We just mechpiston sp1 and sp2 +1500 and took another set of calibs. They turned out yellow this time, so we started the exposure. Plate done. (Lots of sky residual warnings). 04:32Z cart 4 plt 1764, stars on go to field. We had a hard time to estimate our efficiency in this variable seeing/clouds conditions. Our last exposure almost brought us to the limit 15 s/n, but not quite and we had to finish the plate with an additional short expsosure. Plate done. (Some sky-residual warnings). 06:27Z cart 2 plt 2103 mounted. Fk5 used to find the guide stars. 07:09Z Clouds got denser, the first exposure was lost due to the clouds. Plate done. (Sky residual warnings). 08:49Z cart 3 plt 2110. Fk5 used TFGS. Good conditions. Plate done. 09:58Z cart 7 plt 1838. GSOGTF. Again clouds arrived. But we've done that plate too. (sky-residual warnings). endNight finished ok. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5233 22:42Z 22:58Z 100 O -115.06 -110.98 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): y QA Procedures Done (y/n): y UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 31783, plate -9999 ------- 22:33 31783 0.0 bias ----- sequence 31784, plate 1400 ------- 22:57 31784 10.0 flat collimation 22:59 31785 2.0 arc collimation 23:05 31786 2.1 arc collimation 23:08 31787 2.1 arc collimation 23:29 31788 10.0 flat collimation check 23:31 31789 2.0 arc collimation check 23:34 31790 2.1 arc collimation check 23:37 31791 2.1 arc collimation check ----- sequence 31792, plate -9999 ------- 01:08 31792 0.0 bias 01:15 31793 0.0 bias ----- sequence 31794, plate 2111 ------- 02:28 31794 10.0 flat 02:31 31795 2.0 arc 02:36 31796 10.0 flat 02:39 31797 2.0 arc 02:47 31798 10.0 flat 02:50 31799 2.0 arc 03:19 31800 1500.1 target 03:47 31801 1500.1 target 04:16 31802 1500.1 target 04:19 31803 10.0 flat 04:22 31804 2.0 arc ----- sequence 31805, plate 1764 ------- 04:37 31805 10.0 flat 04:39 31806 2.0 arc 05:08 31807 1500.1 target 05:36 31808 1500.1 target 05:59 31809 1200.1 target 06:02 31810 10.0 flat 06:04 31811 2.0 arc 06:19 31812 600.1 target ----- sequence 31813, plate 2103 ------- 06:33 31813 10.0 flat 06:35 31814 2.0 arc 07:10 31815 1392.0 target 07:48 31816 1800.1 target 08:16 31817 1500.2 target 08:19 31818 10.0 flat 08:22 31819 2.0 arc 08:41 31820 900.1 target ----- sequence 31821, plate 2110 ------- 08:54 31821 10.0 flat 08:56 31822 2.0 arc 09:15 31823 900.1 target 09:28 31824 600.2 target 09:44 31825 720.1 target 09:47 31826 10.0 flat 09:49 31827 2.0 arc ----- sequence 31828, plate 1838 ------- 10:02 31828 10.0 flat 10:04 31829 2.0 arc 10:28 31830 1200.2 target 11:01 31831 1800.1 target 11:24 31832 1200.1 target 11:28 31833 10.0 flat 11:30 31834 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 02:56Z 1 2111 105.06 0.0017 60.11 0.0034 -95.74 -0.0039 1.000260 04:43Z 4 1764 51.26 -0.0012 64.02 0.0031 222.62 0.0032 0.999980 06:42Z 2 2103 244.39 0.0063 81.12 0.0024 69.95 0.0615 1.000130 08:59Z 3 2110 269.25 0.0022 70.87 0.0036 101.13 0.0099 1.000090 10:12Z 7 1838 256.31 0.0017 62.53 0.0018 94.99 -0.0095 0.999960 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL 8432 Stays: JL 8433 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 02:56Z 1 2111 1.00026 -2566 -973 0 105 60.1 4.8 12 136 gdr 2.5 04:43Z 4 1764 0.99998 198 1406 100 51 64.0 2.7 19 74 gdr 2.3 06:42Z 2 2103 1.00013 -1284 255 200 244 81.1 1.9 16 76 gdr 1.9 08:59Z 3 2110 1.00009 -889 429 35 269 70.9 4.4 1 22 gdr 1.5 10:12Z 7 1838 0.99996 395 1463 -10 256 62.5 3.8 0 82 gdr 1.5 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:16Z 47 15 10 257 (WSW) 1155 -
