APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday October 21, 2001 (MJD 52204) ---=== OBSERVING TEAM ===--- (APO) Jurek Krzesinski (APO) Stephanie Snedden ---=== OBSERVING PLAN ===--- Spectroscopy (thin cirrostratus clouds) ---=== OBSERVING SUMMARY ===--- Afternoon checkout: Problems with DA: see the problem section. Observations: We tried five cartridges, but due to the weather not one was declared done: cart 1 plt 718 - very low signal to noise ratio, SMEAR done, plate not done. cart 5 plt 694 - very low signal to noise ratio, no SMEAR exp, plate not done. cart 9 plt 709 - no data - az axis problem (correction too big). cart 6 plt 704 - three exposures taken, but plate not done. cart 7 plt 546 - three exposures and SMEAR, plate not done. Problems: -frozen sop window: doNextscience died silently - see problem section. -az axis correction too large (some time lost due to that problem -again)- see problem section. ---=== OBSERVING LOG ===--- Afternoon checkout: Problems with DA, after rebooting them a few times, they went back to normal. 18:25 Telescope opened, cart 1 plt 718 mounted. 18:50 Trying to setup for stars - it was too bright (twilight) so we tried fk5, and found a star with no problem. 19:40 First exposure started. Because of clouds, we got a mariginal (S/N)^2 on the first one. The second exposure was even worse. 20:50 Third doNextScience hung up quietly, sop GUI showed third exposure, but no count down, we checked that the command was issued. sop window was frozen. From another sop window we issued exposureRem, which showed ''0 exposure in progress'', so we destroyed that frozen window, started a new one, issued goStare 0 -init -bias and ... we got a message telling us that there IS exposure in progress. We checked if we can talk to sp1 and sp2 and it was ok. Then we killed all iop processes, started sop from scratches and were able to run goStare normally. All of it looked like there was a variable set to ''exposure in progress'' somewhere in memory, which wasn't released after we killed the sop window. 21:23 Started the third exposure again, and finished it with no problems. We stopped after fourth exposure since we couldn't get (S/N)^2 greater than 2 with 1/2 hour exposure. Smear done. Waiting for the better weather. Cart 3 plt 722 mounted - never observed (clouds). 00:13 Cart 5 plt 694 mounted, 00:28 - first exposure started, and resulted in low signal to noise ratio. Second exposure also resulted in low S/N. Third and last exposure finaly resulted in (S/N)^2 = 3. 02:40 cart 9 plt 709 mounted. We couldn't find star, fk5 didn't help. We tried spiralPattern with no succes. So, we decided there is something wrong with that cart/plt. and mounted another cartridge. However, looking at a problem described below, we are pretty sure, that cart 9 is ok, but we didn't noticed az axis problem until we swaped the cartridge. 03:08 cart 6 plt 704 mounetd. stars not found... Then we noticed that we've got problems with Azimuth axis: Oct 22 02:42:38 sdssmcp tLatch dsc_I_trcInfo Applying correction 42049 to azimuth Oct 22 02:42:38 sdssmcp tLatch dsc_E_trcErr correction for azimuth 42049 is too large and many others like this one since that see the problem section. We refiducialized the telescope in az axis and found fk5 star with offset: RA= 10''. 03:30 cart 6 plt 704 - first exposure. Smear done on clear sky. Plate already expired, so we had to swap cartridges. Plate not done. 05:18 cart 7 plt 546 - first exposure. Stars found with offsets from the previous plate. Smear done at the begining of twilights and probably on thin clouds. Plate not done. endNight rejoiced :) ---=== IMAGING RUN SUMMARY ===--- Run Stripe Flavor Lambda Last Begin End Frame Comments ------------------------------------------------------------------ 2671 100 O bias 76.05 81.84 43 2672 100 O ignore 90.00 94.34 42 ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot --------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields nGood rowMean rowSig colMean colSig rot --------------------------------------------------------------- ---=== SPECTROSCOPY DATA SUMMARY ===--- UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 11408, plate -9999 ------- 22:18 11408 0.0 bias 22:36 11409 0.0 bias ----- sequence 11410, plate 718 ------- 00:09 11410 0.0 bias 01:32 11411 10.0 flat 01:34 11412 2.0 arc 01:58 11413 901.0 target 02:32 11414 1802.0 target ----- sequence 11415, plate -9999 ------- 03:13 11415 0.0 bias ----- sequence 11416, plate 718 ------- 03:44 11416 1200.0 target 04:17 11417 1801.0 target 04:24 11418 240.0 smear 04:26 11419 10.0 flat 04:29 11420 2.0 arc ----- sequence 11421, plate 694 ------- 06:19 11421 10.0 flat 06:21 11422 2.0 arc 07:06 11423 1503.0 target 07:40 11424 1502.0 target 08:13 11425 1501.0 target 08:17 11426 10.0 flat 08:19 11427 2.0 arc ----- sequence 11428, plate 704 ------- 09:26 11428 10.0 flat 09:28 11429 2.0 arc 09:51 11430 901.0 target 10:14 11431 1202.0 target 10:21 11432 240.0 smear 10:44 11433 1204.0 target 10:47 11434 10.0 flat 10:49 11435 2.0 arc ----- sequence 11436, plate 546 ------- 11:07 11436 10.0 flat 11:09 11437 2.0 arc 11:35 11438 900.0 target 11:52 11439 900.0 target 11:59 11440 240.0 smear 12:17 11441 900.0 target 12:21 11442 10.0 flat 12:23 11443 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument getclock Az Alt Rot Scale ------------------------------------------------------------------------------ 19:44 1 718 1003715052 0.000642 -0.001064 0.049890 0.999990 21:58 1 718 1003723101 0.000642 -0.001064 0.049890 0.999800 01:25 5 694 1003735501 0.000642 -0.001064 0.049890 1.000050 03:43 6 704 1003743782 0.002214 0.002573 0.000000 1.000040 05:50 7 546 1003751433 0.002214 0.002573 0.000000 1.000270 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL4566 Stays: JL4567 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 19:44 1 718 0.99999 99 1233 -50 30 44.0 11.3 11 249 - 1.5 21:57 1 718 0.99980 1974 2675 -150 -17 47.2 11.1 12 258 - 1.3 01:25 5 694 1.00005 -493 614 -150 -33 52.5 11.7 11 260 - 1.5 03:43 6 704 1.00004 -394 776 -100 -52 43.6 10.4 15 263 - 1.6 05:49 7 546 1.00027 -2665 -1278 -200 126 71.3 10.5 16 268 - 1.6 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 16:18 61 10 5 263 (W) 313 - mcl 16:54 60 11 8 267 (W) 341 - mcl 17:25 60 12 5 261 (W) 326 - mcl 00:30 53 15 13 256 (WSW) 408 - mcl 01:36 53 15 14 257 (WSW) 384 - pcl 02:36 52 15 18 271 (W) 362 - pcl 04:10 50 15 13 266 (W) 326 - pcl ---=== TELESCOPE STATUS ===--- 17:45 Doors cracked, fans on 18:25 telescope opened, cart 1 plt 718 mounted. 06:30 telescope stowed in enclosure at 30 deg alt.

From another sop window we issued exposureRem, which showed ''0 exposure in progress'', so we destroyed that frozen window, started a new one, issued goStare 0 -init -bias and ... we got a message telling us that there IS exposure in progress. We checked if we can talk to sp1 and sp2 and it was ok. Then we killed all iop processes, started sop from scratche and were able to run goStare normally. All of it looked like there was a variable set to ''exposure in progress'' somewhere in memory, which wasn't released after we killed the sop window. Note that once we restarted SOP, the efficiency meter read zero for every fiber . Issuing another loadCart fixed the problem. az correction too large: ------------------------ here are too large correction from murmur: Oct 22 02:21:28 sdssmcp tLatch dsc_E_trcErr correction for azimuth 29066 is too large Oct 22 02:21:36 sdssmcp tLatch dsc_E_trcErr correction for azimuth 41241 is too large Oct 22 02:21:51 sdssmcp tLatch dsc_E_trcErr correction for azimuth 41960 is too large Oct 22 02:21:58 sdssmcp tLatch dsc_E_trcErr correction for azimuth 41964 is too large Oct 22 02:22:22 sdssmcp tLatch dsc_E_trcErr correction for azimuth 41965 is too large Oct 22 02:22:29 sdssmcp tLatch dsc_E_trcErr correction for azimuth 42010 is too large Oct 22 02:22:40 sdssmcp tLatch dsc_E_trcErr correction for azimuth 42049 is too large Oct 22 02:42:38 sdssmcp tLatch dsc_E_trcErr correction for azimuth 42049 is too large Oct 22 02:42:54 sdssmcp tLatch dsc_E_trcErr correction for azimuth 41868 is too large Oct 22 02:43:02 sdssmcp tLatch dsc_E_trcErr correction for azimuth 41974 is too large Oct 22 02:43:09 sdssmcp tLatch dsc_E_trcErr correction for azimuth 41819 is too large Oct 22 02:43:17 sdssmcp tLatch dsc_E_trcErr correction for azimuth 41986 is too large Oct 22 02:43:24 sdssmcp tLatch dsc_E_trcErr correction for azimuth 41821 is too large Oct 22 02:43:32 sdssmcp tLatch dsc_E_trcErr correction for azimuth 41946 is too large Oct 22 02:43:39 sdssmcp tLatch dsc_E_trcErr correction for azimuth 41908 is too large Oct 22 02:43:47 sdssmcp tLatch dsc_E_trcErr correction for azimuth 41698 is too large Oct 22 02:43:55 sdssmcp tLatch dsc_E_trcErr correction for azimuth 38985 is too large Oct 22 02:45:16 sdssmcp tLatch dsc_E_trcErr correction for azimuth 38985 is too large Oct 22 02:46:26 sdssmcp tLatch dsc_E_trcErr correction for azimuth 38985 is too large Oct 22 02:47:22 sdssmcp tLatch dsc_E_trcErr correction for azimuth 38985 is too large Oct 22 02:51:45 sdssmcp tLatch dsc_E_trcErr correction for azimuth 38985 is too large Oct 22 02:52:15 sdssmcp tLatch dsc_E_trcErr correction for azimuth 38985 is too large Oct 22 03:01:33 sdssmcp tLatch dsc_E_trcErr correction for azimuth 38985 is too large
