We started with the imager. In a SEGUE version of IOP, we did a clacStripeParams and got an error; (see problems section). There were also problems with goDrift and skippy. The former was resolved, but the latter was not. Because most of the other shake items had been completed, we decided to switch to spectro for the rest of the night. 05:57Z Cart 06, plate 1037 (lowz45), field found with Fk5 star; seeing was about 2.2" which increased exposure times. Three exposures and smear completed before plate expired for the night. Total S/N2 = 10.9 07:46Z Cart 03, plate 1103 (merged48), stars on slew; seeing was about 2.4" Plate completed in three exposures. 09:25Z Cart 05, plate 1121 (munn49), stars on slew; seeing was about 2.3" Plate completed in three exposures. M1 Temp: -------- Watcher complained all night about M1's temp (see problems section). ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4074 00:28Z 00:45Z 100 O 46.25 50.47 40 bias Mounted, unlatched, encl. 4076 03:03Z 05:30Z 1062 N 74.80 111.77 260 engineering ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- 4076 21 4 124 -6.700 0.136 -2.100 0.138 -0.00098 199 64 4076 73 4 22 -6.800 1.033 -1.100 1.920 -0.01289 199 60 4076 126 4 60 -6.300 0.173 -2.100 0.140 -0.00369 198 56 ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ 4076 31 1 63 341 76 0.264 0.274 0.626 0.173 -0.00211 4076 31 1 63 341 71 0.559 0.155 0.672 0.343 -0.00226 4076 31 1 63 341 76 0.645 0.165 0.428 0.361 -0.00144 4076 31 1 63 341 74 0.526 0.176 0.388 0.238 -0.00130 4076 31 1 63 341 73 0.322 0.188 0.327 0.200 -0.00110 4076 48 1 62 341 77 0.298 0.212 1.186 0.266 -0.00399 4076 48 1 62 341 70 0.386 0.300 1.191 0.228 -0.00400 4076 48 1 62 341 79 0.428 0.300 1.273 0.335 -0.00428 4076 48 1 62 341 77 0.256 0.264 1.323 0.234 -0.00445 4076 48 1 62 341 63 0.056 0.222 1.204 0.301 -0.00405 4076 80 1 59 341 77 0.207 0.324 0.871 0.362 -0.00293 4076 80 1 59 341 69 0.187 0.280 0.835 0.269 -0.00281 4076 80 1 59 341 69 0.251 0.375 0.781 0.252 -0.00263 4076 80 1 59 341 70 0.184 0.486 0.778 0.153 -0.00261 4076 80 1 59 341 61 0.233 0.371 0.731 0.224 -0.00246 4076 103 1 58 342 78 0.570 0.198 1.662 0.326 -0.00559 4076 103 1 58 342 70 0.660 0.234 1.576 0.348 -0.00530 4076 103 1 58 342 85 0.553 0.368 1.537 0.289 -0.00517 4076 103 1 58 342 73 0.549 0.335 1.670 0.369 -0.00562 4076 103 1 58 342 56 0.783 0.305 1.710 0.206 -0.00575 4076 135 1 55 342 13 1.539 0.296 1.102 0.306 -0.00370 4076 135 1 55 342 33 1.409 0.400 1.299 0.388 -0.00437 4076 135 1 55 342 20 1.079 0.385 1.071 0.582 -0.00360 4076 135 1 55 342 7 0.908 0.314 1.340 0.387 -0.00451 ---=== 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 22013, plate -9999 ------- 00:31 22013 0.0 bias ----- sequence 22016, plate 1037 ------- 06:22 22016 10.0 flat 06:25 22017 2.0 arc 06:43 22018 900.1 target 07:06 22019 1200.1 target 07:29 22020 1200.1 target 07:37 22021 240.0 smear ----- sequence 22022, plate 1103 ------- 07:53 22022 10.0 flat 07:55 22023 2.0 arc 08:18 22024 1200.1 target 08:45 22025 1400.1 target 09:13 22026 1500.1 target 09:20 22027 240.0 smear ----- sequence 22028, plate 1121 ------- 09:32 22028 10.0 flat 09:34 22029 2.0 arc 10:02 22030 1500.1 target 10:30 22031 1500.1 target 10:58 22032 1500.1 target 11:06 22033 240.0 smear ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 06:17Z imager 35.19 0.0049 51.73 -0.0015 208.91 0.0164 0.999900 07:51Z imager -12.29 0.0051 56.60 -0.0001 169.61 0.0004 1.000190 09:36Z imager -6.30 0.0038 57.03 -0.0004 174.63 -0.0115 1.000210 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL6636, 6637, 6638, 6639, 6640, 6641,6648 Stays: JL6642, 6643, 6644, 6645, 6646, 6647 6649 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 06:17Z unknown 0.99990 986 1743 -250 35 51.8 14.6 22 78 gdr 2.2 07:50Z unknown 1.00019 -1875 -642 -250 -12 56.6 13.8 22 76 gdr 2.4 09:37Z unknown 1.00021 -2073 -806 -250 -6 57.0 13.1 22 73 gdr 2.3 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 21:15Z 70 41 15 48 (NE) 561 -

The fix worked, and we were able to move to the field with scanStripe. However, goDrift would not work. We contacted Eric again, and he asked that we source his version of scan.tcl, which worked. But, skippy would not run, and we were unable to resolve this problem. Problem two ------------ Watcher complained all night about M1's temp with the following message: m1 temp (Excessive M1 - PMSS Temperature Differential:Excessive Telescope - Ambient Temperature Differential:Excessive Temperature Radial Gradient:: 2003-08-22 02:30:46Z ) The M1 temp graphic display in TPM looked atypical, and most on the temp sensor readings on Module #0 Block #1, #2, #3, #4, and #5 were all ~24 degrees.
