APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday September 18, 2008 (MJD 54728) ---=== OBSERVING TEAM ===--- Kaike Pan Audrey Simmons Scott Fleming (MARVELS) ---=== OBSERVING PLAN ===--- MARVELS Science! ---=== OBSERVING SUMMARY ===--- Mostly clear with good seeing all night. Finished: Cart 2, plate 3019 Cart 6, plate 3029 Obtained signal on: Cart 8, plate 3032 Cart 5, plate 3030 Cart 9, plate 3033 Cart 7, plate 3017 Cart 3, plate 3031 Note: One of the screws from inside the female gang connector on cartridge 8 fell out. We did not feel comfortable replacing it because of how close we would get to the fibers. ---=== OBSERVING LOG ===--- Afternoon: ---------- Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 114G 21G 85% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 688G 183G 79% /data sdssfiles1:/data1/data 1.5T 648G 745G 47% /files Note: The wepage has not been updated for a while. We need to know soon which MJD's are okay to delete. Spectro collimation set for ~10C tonight. 00:15Z - Started ventilating with the doors and louvers open, fans on. Night: ------ 01:15Z - Opened enclosure to clear skies. 01:30Z - Mounted cart 2, marvels_pre201 plate 3019. Field A is done. 01:42Z - goToField cart 2, plate 3019B. Used fk5 to find field. Guide stars are pretty faint.

This plate is DONE. 02:45Z - Calibrations. 02:50Z - Mounted cart 8, jun08b marvels commissioning plate 3032. Used fk5 to find field. 03:09Z - MARVELS team started the first exposure (40 minutes). The guider reads the seeing to be ~1.2", but the stars look rather big... 03:52Z - Calibrations. Note: One of the screws from inside the female gang connector on this cartridge fell out. We did not feel comfortable replacing it since we would come very close to the fibers. 04:10Z - Another 40 min exposure. 04:50Z - Calibrations. 04:51Z - Mounted cart 5, jun08b marvels commissioning plate 3030. GSFOGTF. 05:05Z - Started 40 min exposure. Seeing 1.0" 05:55Z - Calibrations. 06:02Z - Started next 40 min exposure. Seeing 1.1" 06:57Z - Calibrations. 06:58Z - Mounted cart 9, jun08 marvels commissioning plate 3033. GSFOGTF. 07:07Z - Started 40 min exposure. Seeing 1.1" 07:44Z - Calibrations. 07:53Z - Mounted cart 6, marvels_pre jul08a plate 3029B (A is done). Used fk5 star to find field. Guide stars look normal, but they are not centered. 08:05Z - Precals, #54648-49. 08:12Z - 7 second exposure, #54650. Seeing 1.0" 08:14Z - " " ", #54651 08:18Z - " " ", #54652 08:21Z - " " ", #54653 08:24Z - " " ", #54654 08:27Z - " " ", #54655 08:30Z - 12 second exposure, #54656 08:33Z - " " ", #54657 08:36Z - " " ", #54658 08:39Z - " " ", #54659 08:42Z - " " ", #54660 08:46Z - Postcals, #54661-62. This plate is DONE. 08:58Z - Mounted cart 7, marvels_pre201 plate 3017A. GSFOGTF. Note: There were four options to observing this plate. When loading the cartridge, you are asked to put in 0 or 1 for fields A and B. Since this plate was designed for use during the summer months, the plate design is likely outdated. For the more recent plate designs, you need to type in 2 or 3 for A and B. All guide stars were seen on goToField, although some were still not centered. 09:13Z - Precals, #54663-64 09:19Z - 7 second exposure, #54665.

Used fk5. The field is too close to the moon. We will observe this field another night. 10:30Z - Calibrations. 10:38Z - Mounted cart 3, jun08b marvels commissioning plate 3031. Guide fibers 9 and 10 are broken. Used fk5 in fiber 6 and cleared the previous offsets to find the field. There are 7 stars to guide on. 10:53Z - Started 40 min exposure. Seeing 1.1" 11:34Z - 15 min exposure. 11:50Z - Calibrations. 11:55Z - Closed enclosure. 12:19Z - endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7687 23:37Z 23:48Z 100 O 61.76 64.38 32 ignore 7689 09:41Z 09:44Z 100 O -146.86 -146.18 19 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 54626, plate -9999 ------- 23:41 54626 0.0 bias ----- sequence 54627, plate 3029 ------- 23:46 54627 10.0 flat 23:51 54628 10.0 flat 23:54 54629 2.0 arc 23:57 54630 2.0 arc 23:59 54631 2.0 arc ----- sequence 54632, plate -9999 ------- 00:40 54632 0.0 bias ----- sequence 54633, plate 3019 ------- 02:00 54633 10.0 flat 02:03 54634 2.0 arc 02:07 54635 8.0 target 02:10 54636 7.0 target 02:13 54637 7.0 target 02:16 54638 8.0 target 02:19 54639 8.0 target 02:22 54640 12.0 target 02:26 54641 12.0 target 02:29 54642 13.0 target 02:33 54643 13.0 target 02:36 54644 13.0 target 02:39 54645 13.0 target 02:42 54646 10.0 flat 02:45 54647 2.0 arc ----- sequence 54648, plate 3029 ------- 08:07 54648 10.0 flat 08:10 54649 2.0 arc 08:14 54650 8.0 target 08:17 54651 8.0 target 08:20 54652 8.0 target 08:23 54653 7.0 target 08:26 54654 8.0 target 08:29 54655 8.0 target 08:33 54656 13.0 target 08:36 54657 13.0 target 08:39 54658 13.0 target 08:42 54659 13.0 target 08:45 54660 13.0 target 08:48 54661 10.0 flat 08:51 54662 2.0 arc ----- sequence 54663, plate 3017 ------- 09:15 54663 10.0 flat 09:18 54664 2.0 arc 09:21 54665 8.0 target 09:29 54666 7.0 target 09:32 54667 7.0 target 09:35 54668 8.0 target 09:38 54669 8.0 target 09:42 54670 8.0 target 09:45 54671 13.0 target 09:48 54672 13.0 target 09:51 54673 13.0 target 09:54 54674 13.0 target 09:57 54675 13.0 target 10:00 54676 13.0 target 10:04 54677 8.0 target 10:07 54678 10.0 flat 10:10 54679 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 02:05Z 2 3019 -85.81 -0.0132 73.10 0.0011 104.41 0.0235 1.000120 03:10Z 8 3032 208.47 0.0004 70.50 0.0010 37.77 0.0094 1.000230 05:19Z 5 0 -6.82 -0.0033 76.02 0.0013 173.88 0.0156 1.000130 07:56Z 6 3029 -2.76 -0.0033 77.66 0.0013 177.56 0.0156 1.000200 08:11Z 6 3029 -18.93 0.0006 77.05 0.0007 163.07 0.0360 0.999950 09:21Z 7 3017 161.62 0.0006 71.98 0.0007 -24.11 0.0360 1.000150 10:54Z 3 3031 197.33 -0.0011 49.52 0.0006 44.21 0.0335 1.000150 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 02:05Z 2 3019 1.00012 -1184 356 210 -86 73.1 9.8 7 175 - 1.3" 03:10Z 8 3032 1.00023 -2270 -540 210 208 70.5 9.9 2 179 - 1.2" 05:20Z 5 0 1.00013 -1283 130 70 -7 76.0 9.9 4 190 - 1.0" 07:56Z 6 3029 1.00020 -1974 -346 170 -2 78.6 8.9 4 186 - 1.1" 08:11Z 6 3029 0.99995 494 1700 170 -19 77.0 9.0 3 191 - 1.0" 09:21Z 7 3017 1.00015 -1480 -98 0 162 72.0 9.5 4 276 - 1.1" 10:54Z 3 3031 1.00015 -1480 -44 0 197 49.5 8.6 6 351 - 1.1" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:58Z 58 43 6 245 (WSW) 537 - Clear 23:30Z 56 41 4 225 (SW) 478 - " 00:01Z 54 41 5 257 (WSW) 473 - " 00:33Z 53 41 6 215 (SW) 509 - " 01:05Z 50 40 4 183 (S) 529 - " 01:35Z 49 39 5 180 (S) 523 - " 02:06Z 49 39 6 182 (S) 634 - " 02:37Z 49 39 5 185 (S) 663 - " 03:07Z 50 38 2 188 (S) 685 - " 03:38Z 50 38 2 230 (SW) 694 - " 04:09Z 51 36 2 251 (WSW) 590 - " 04:39Z 50 37 2 234 (SW) 636 - " 05:10Z 50 38 2 195 (SSW) 702 - " 05:47Z 48 38 2 178 (S) 693 - " 06:19Z 47 38 5 186 (S) 709 - " 06:51Z 48 38 4 197 (SSW) 742 - " 07:21Z 48 38 3 189 (S) 682 - " 07:51Z 47 36 4 186 (S) 740 - " 08:23Z 48 35 1 193 (SSW) 695 - " 08:56Z 49 38 6 312 (NW) 689 - Partly cloudy 09:27Z 49 38 5 329 (NNW) 724 - Clear 09:59Z 48 39 9 327 (NNW) 804 - " 10:31Z 47 39 5 351 (NNW) 854 - " 11:01Z 46 40 7 355 (NNW) 1019 - " 11:31Z 47 40 7 344 (NNW) 954 - " 12:01Z 47 40 5 353 (NNW) 1547 - " ---=== TELESCOPE STATUS ===--- 00:15Z - Began ventilation.
