Pointing Model Test Guider ---=== OBSERVING SUMMARY ===--- The night was lost to clouds and rain. We had a spectro auto-fill problem; see log. ---=== OBSERVING LOG ===--- Afternoon: ---------- 23:00Z Started the checkout. 23:05Z Restarted the servers 23:10Z Imager bias 23:14Z Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 126G 8.8G 94% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 815G 57G 94% /data sdssfiles1p:/data1/data 1.5T 709G 684G 51% /files hub25mp:/home 92G 34G 59G 37% /home_hub25m 00:19Z Checked mirror numbers Night: ------ 01:33Z Sunset 03:02Z Evening twilight 04:39Z Moonset 10:00Z When we shutdown the telescope, the spectro LN2 autofill was running. We noticed that connector for sp2 was leaking LN2, which would not allow the secondary dewar to fill or the system to shut off. We got French out of bed to check the problem. He thinks the seals in the connector will need to be replaced. 10:56Z endNight finished and was happy. 11:11Z Morning twilight 12:39Z Sunrise ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 8012 23:09Z 00:05Z 100 O 30.65 44.91 76 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ---=== 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 22:03Z 60 47 6 233 (SW) 1432 - 22:35Z 59 45 5 264 (W) 1562 - 23:09Z 58 43 8 240 (WSW) 1523 - 23:41Z 57 44 7 223 (SW) 1462 - 00:11Z 56 44 4 242 (WSW) 1638 - 00:42Z 57 41 8 192 (SSW) 1808 - 01:12Z 56 42 2 216 (SW) 1791 - 01:42Z 56 42 4 260 (W) 1893 - 02:12Z 55 42 4 262 (W) 1909 - 02:42Z 55 43 1 215 (SW) 1697 - 03:12Z 54 43 4 229 (SW) 1814 - 03:43Z 55 43 7 198 (SSW) 1794 - 04:15Z 55 43 6 217 (SW) 2131 - 04:47Z 54 44 12 205 (SSW) 2649 - 05:19Z 55 44 11 199 (SSW) 2598 - 05:49Z 54 45 9 180 (S) 2721 - 06:19Z 55 45 12 179 (S) 2715 - 06:50Z 55 44 8 182 (S) 2160 - 07:20Z 54 44 6 192 (SSW) 2152 - 07:50Z 54 44 7 225 (SW) 2071 - 08:20Z 52 44 7 232 (SW) 2126 - 08:50Z 54 44 8 220 (SW) 1850 - 09:20Z 53 44 7 203 (SSW) 1647 - 09:51Z 52 45 6 209 (SSW) 1467 - 10:23Z 51 45 5 188 (S) 1340 - 10:57Z 52 45 7 201 (SSW) 1218 - ---=== TELESCOPE STATUS ===--- Did not open No interlocks bypassed.
