Second half was better. 11 exposures. Observed 7 different ET plates. Note: GN2 Grade 5 is getting low. ---=== OBSERVING LOG ===--- Afternoon: --------- Afternoon checkout went smoothly. Night: ----- 01:49Z - Started with Cartridge 6, plate E8016. Needed an fk5. One 50-minute exposure with the iodine cell in place (data). 02:56Z - Cartridge 2, plate E8018. GSOGTF One 50-minute exposure with the iodine cell in place (data). 04:04Z - Cartridge 9, plate E8017. GSOGTF Two 50-minute exposures with the iodine cell in place (2Xdata). 06:00Z - Cartridge 3, plate E8024. GSOGTF One 50-minute exposure with the iodine cell in place (data). 07:07Z - Cartridge 1, plate E8026. GSOGTF Two 50-minute exposures with the iodine cell in place (2Xdata). 09:04Z - Cartridge 8, plate E8021. Needed an fk5. One 50-minute exposure with the iodine cell in place (data). 10:00Z - We had a rotator abort when slewing from Cartridge 8 to the instrument change position and there was no evidence of the ET fiber cable contacting the telescope (which was the cause for the previous night's rotator abort). 10:11Z - Cartridge 7, plate E8022. Needed an fk5. One 50-minute exposure with the iodine cell in place (data). 11:10Z - Cartridge 1, plate E8026. GSOGTF One 50-minute exposure with the iodine cell in place (data). One 30-minute exposure with the iodine cell in place (data). ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- ---=== 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 ----- sequence 43232, plate -9999 ------- 22:38 43232 0.0 bias 22:41 43233 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 01:59Z 6 8016 25.88 -0.0016 54.19 -0.0005 201.50 -0.0148 1.000000 03:14Z 2 8018 191.73 -0.0016 81.64 -0.0005 13.08 -0.0148 1.000070 04:07Z 9 8017 -14.22 -0.0016 61.77 -0.0005 168.02 -0.0148 1.000030 06:01Z 3 8024 19.76 -0.0016 74.61 -0.0005 197.39 -0.0148 1.000000 07:17Z 1 8026 139.56 -0.0016 56.36 -0.0005 -66.94 -0.0148 0.999970 09:12Z 8 8021 94.65 -0.0014 51.40 0.0010 251.15 -0.0148 1.000090 10:16Z 7 8022 111.17 0.0007 59.93 0.0031 -90.72 -0.0176 1.000120 11:24Z 1 8026 212.58 -0.0000 62.79 0.0008 49.73 -0.0204 1.000030 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 01:58Z 6 8016 1.00000 0 1368 200 26 54.2 -1.4 7 136 ---- 2.0 03:14Z 2 8018 1.00007 -691 745 200 192 81.6 -0.6 3 51 ---- 3.5 04:07Z 9 8017 1.00003 -296 978 75 -14 61.8 -0.3 3 114 ---- 3.0 06:01Z 3 8024 1.00000 0 1075 -50 20 74.6 1.6 9 110 ---- 1.9 07:17Z 1 8026 0.99997 296 1282 -125 140 56.3 3.5 6 117 ---- 1.8 09:08Z 8 8021 1.00009 -889 416 -25 95 51.3 3.3 10 125 ---- 1.5 10:16Z 7 8022 1.00012 -1185 157 -15 111 59.9 3.7 11 127 ---- 1.9 11:24Z 1 8026 1.00003 -296 865 -35 212 62.8 4.0 10 129 ---- 1.6 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 21:11Z 36 -8 3 80 (E) 394 - 21:44Z 31 4 2 265 (W) 382 - 22:16Z 32 2 4 253 (WSW) 356 - 22:47Z 35 0 4 72 (ENE) 330 - 23:20Z 28 1 1 303 (WNW) 375 - 23:52Z 28 0 1 284 (WNW) 294 - 00:20Z 32 -3 2 190 (S) 296 - 00:52Z 28 -3 3 51 (NE) 315 - 01:25Z 29 -9 3 83 (E) 197 - 01:58Z 29 -9 6 146 (SE) 194 - 02:29Z 29 -10 10 105 (ESE) 162 - 03:01Z 30 -20 8 78 (ENE) 175 - 03:33Z 31 -26 3 49 (NE) 282 - 04:06Z 31 -27 2 98 (E) 399 - 04:38Z 32 -27 4 110 (ESE) 700 - 05:10Z 33 -26 7 94 (E) 751 - 05:42Z 33 -25 6 101 (E) 681 - 06:14Z 35 -24 6 100 (E) 657 - 06:46Z 36 -22 9 121 (ESE) 687 - 07:17Z 38 -22 6 116 (ESE) 617 - 07:48Z 37 -23 9 120 (ESE) 655 - 08:19Z 37 -23 9 127 (SE) 601 - 08:51Z 38 -22 9 125 (SE) 622 - 09:23Z 38 -21 10 125 (SE) 556 - 09:55Z 38 -21 8 128 (SE) 381 - 10:27Z 38 -21 9 120 (ESE) 386 - 11:00Z 38 -22 10 126 (SE) 357 - 11:32Z 39 -23 9 128 (SE) 262 - 12:05Z 41 -18 9 134 (SE) 202 - 12:36Z 42 -19 8 138 (SE) 184 - ---=== TELESCOPE STATUS ===--- 23:59Z - Began ventilation.
