APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday September 22, 2004 (MJD 53271) ---=== OBSERVING TEAM ===--- Steph Snedden (Parenthetical Titler and swing) Atsuko (Morale Officer) Nitta Dan (QA Poobah) Long Craig (Big Apple) Loomis - support Scot (Union Boss of the SDSS working class) - working w/ Craig ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We finished 5 plates ( 1558, 1559, 1858, 1883, 1902) and got an hour of imaging. Run 4851 72 N 175.8 to -173 (ramps subtracted) As fate would have it, the plates got the better seeing. Checkout the APO weather plots and see if you can tell when the imager was on :). http://galileo.apo.nmsu.edu/sky/weather/latestweather.html ---=== OBSERVING LOG ===--- Swing: ------ The sos RAID had one disk drive shut down in a not-nice fashion (sorry, I don't have the details). Craig worked on it from his NYC hotel room, but be aware if sos starts having problems, it may be hardware related, and we may have to get by without sos. As I write this (23:08Z), sos is behaving. There is a filesystem called "none"...does that mean the one drive is still down? If so, it looks like the RAID is doing its job. The spectro focus was adjusted slightly. Details at the end of the log. The rest of afternoon checkout was uneventful. Night: ------ 00:35Z Doors Open, Fans On. 01:05Z Enclosure Open. 01:40Z Cartridge 1 1858 seguetest96 15.7 33.3 22.9 34.8 guide stars on slew. 01:41Z Got error message about guider frame not arriving for the second frame of a focus sequence. This had the effect of halting the sequence after one frame. 02:03Z First science 28660 b1 flats show several small specks. It may be a chance alignment of the fibers on the chip illuminating more of them, but it does look like there are more now than a week ago. Steph in some cloudcam frames between 02:20 - 02:50. Camera recentered in mount. Done in four exposures. 03:35Z instChange 03:39Z Cartridge 6 1883 seguefaint98 37.8 39.9 37.3 46.7 27.8 20.0 26.2 19.5 53265 --------------------- Guide stars on slew. 65.6 59.9 63.5 65.2 03:45Z preCalib 03:54Z First science 28668 Done in 4 additional exposures 05:29Z instChange 05:32Z Cartridge 8 1902 segue98 14.0 16.6 23.4 23.1 05:37Z preCalib 05:46Z First science 28676 Bright sky background due to moon nearby.

Seeing now over 2 arcseconds. 08:31Z 130 -170 Ending drift, and taking bias. Run 4852 Bias 08:33Z Starting bias drift. Will try imaging again once bias finishes, hoping that the seeing will have returned to acceptable values. 08:55Z scanStripe 72 N -176 Checking if seeing is acceptable again. Backing up to cover bad area in previous scan. Run 4853 72 N -174.6 to nowhere 09:22Z Seeing staying over 1.8, so giving up and switching to spectro. 09:35Z Cartridge 2 1559 lowz74 15.3 15.5 15.7 17.2 26.9 23.7 29.1 24.4 53265 -------------------- 42.2 39.2 44.8 41.6 Guide stars on slew. Of course as soon as we switched back to spectroscopy, the wind changed direction. 09:52Z First science 28683 done in two (one really, but we didn't wait for the numbers before starting a second exposure, and decided to let it finish rather than abort it). 10:28Z instChange 10:33Z Cartridge 7 1558 lowz74 32.5 32.3 35.4 34.9 preCalib numbers are close to the limit in xsigma and wsigma but if we took the time to collimate, we couldn't finish the plate. done in three exposures (though last exposure went well past the expiration time). postCalibs OK, so stayed in spec. 12:00Z Enclosure closed. SoS behaved all night. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4851 07:16Z 08:31Z 72 N 171.38 -170.02 138 science 4852 08:33Z 08:53Z 100 O -159.98 -154.93 47 bias 4853 09:00Z 09:20Z 72 N -176.80 -171.71 48 ignore ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- 4851 14 1 14 -6.700 0.060 0.200 0.099 0.02884 231 78 4851 14 4 84 -6.900 0.734 0.100 0.282 0.02934 231 78 4851 67 4 92 -7.800 0.707 0.000 0.328 0.03209 229 79 4851 119 4 68 -8.700 0.606 -0.500 0.448 0.03525 226 79 4853 15 4 94 -6.000 0.151 2.300 0.153 0.00898 255 68 ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ 4851 25 1 78 309 28 -0.092 0.203 -9.264 0.159 0.03114 4851 25 1 78 309 35 -0.150 0.164 -9.130 0.203 0.03070 4851 25 1 78 309 33 0.004 0.178 -9.110 0.177 0.03063 4851 25 1 78 309 37 -0.133 0.193 -9.122 0.167 0.03067 4851 25 1 78 309 28 -0.127 0.144 -9.132 0.264 0.03070 4851 43 1 79 310 18 0.036 0.144 -9.618 0.087 0.03234 4851 43 1 79 310 21 0.106 0.223 -9.455 0.151 0.03179 4851 43 1 79 310 26 0.188 0.233 -9.556 0.221 0.03213 4851 43 1 79 310 35 -0.003 0.231 -9.610 0.111 0.03231 4851 43 1 79 310 27 -0.022 0.214 -9.615 0.150 0.03233 4851 77 1 79 311 20 0.032 0.327 -10.500 0.183 0.03530 4851 77 1 79 311 19 -0.019 0.243 -10.474 0.263 0.03522 4851 77 1 79 311 16 -0.185 0.328 -10.353 0.204 0.03481 4851 77 1 79 311 28 -0.079 0.355 -10.511 0.337 0.03534 4851 77 1 79 311 26 -0.103 0.390 -10.378 0.302 0.03489 4851 94 1 79 313 20 0.735 0.211 -10.491 0.337 0.03527 4851 94 1 79 313 22 0.896 0.247 -10.696 0.314 0.03596 4851 94 1 79 313 17 0.802 0.333 -10.529 0.272 0.03540 4851 94 1 79 313 19 0.727 0.175 -10.835 0.259 0.03643 4851 94 1 79 313 18 0.750 0.276 -10.936 0.394 0.03677 ---=== 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 28642, plate 1858 ------- 22:35 28642 10.0 flat 22:37 28643 2.0 arc 23:04 28644 2.1 arc 23:07 28645 2.1 arc 23:27 28646 10.0 flat 23:29 28647 2.0 arc 23:39 28648 10.0 flat 23:41 28649 2.0 arc 23:54 28650 10.0 flat 23:57 28651 2.0 arc 00:01 28652 2.1 arc 00:04 28653 2.1 arc 00:22 28654 2.1 arc 00:25 28655 2.1 arc ----- sequence 28656, plate -9999 ------- 00:46 28656 0.0 bias 01:19 28657 0.0 bias ----- sequence 28658, plate 1858 ------- 15.7 33.3 22.9 34.8 01:53 28658 10.0 flat 01:55 28659 2.0 arc 02:20 28660 900.1 target 02:43 28661 1200.1 target 03:06 28662 1200.1 target 03:29 28663 1200.1 target 03:32 28664 10.0 flat 03:34 28665 2.0 arc ----- sequence 28666, plate 1883 ------- 37.8 39.9 37.3 46.7 03:48 28666 10.0 flat 27.8 20.0 26.2 19.5 53265 03:50 28667 2.0 arc --------------------- 04:16 28668 1200.1 target 65.6 59.9 63.5 65.2 04:39 28669 1200.1 target 05:02 28670 1200.1 target 05:22 28671 1000.1 target 05:25 28672 10.0 flat 05:27 28673 2.0 arc ----- sequence 28674, plate 1902 ------- 14.0 16.6 23.4 23.1 05:40 28674 10.0 flat 05:42 28675 2.0 arc 06:04 28676 1000.1 target 06:28 28677 1200.1 target 06:51 28678 1200.1 target 06:54 28679 10.0 flat 06:56 28680 2.0 arc ----- sequence 28681, plate 1559 ------- 15.3 15.5 15.7 17.2 09:45 28681 10.0 flat 26.9 23.7 29.1 24.4 53265 09:47 28682 2.0 arc -------------------- 10:09 28683 900.1 target 42.2 39.2 44.8 41.6 10:27 28684 900.1 target ----- sequence 28685, plate 1558 ------- 32.5 32.3 35.4 34.9 10:40 28685 10.0 flat 10:43 28686 2.0 arc 11:07 28687 1200.1 target 11:29 28688 1200.1 target 11:47 28689 900.1 target 11:51 28690 10.0 flat 11:53 28691 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 01:51Z 1 1858 178.25 0.0009 44.48 -0.0004 -7.35 -0.0126 1.000100 03:54Z 6 1883 113.18 0.0002 55.54 0.0009 -92.58 -0.0150 1.000180 05:53Z 8 1902 19.98 0.0003 55.58 0.0004 196.59 0.0002 1.000180 09:55Z 2 1559 -13.90 -0.0021 56.38 0.0000 168.27 0.0086 1.000180 10:50Z 7 1558 -38.94 -0.0004 50.54 -0.0007 148.00 -0.0243 1.000180 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL7825,26,27,28,29,30,37 Stays: JL7831,32,33,34,35,36,38 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 01:51Z 1 1858 1.00010 -988 432 50 178 44.5 10.1 8 311 -
