The first copy was not yet complete and was mailed by mistake (the "mail" rather than "edit" button was accidentally clicked). When we arrived this afternoon, we found the VME problems from the previous night had fixed themselves (perhaps the mid-morning restart of the servers finally cleared the problems). Since it was totally overcast with high humidity and blowing snow, it was decided to continue with Mamoru's MSP linearity tests. It cleared by 0200 but blowing snow kept us closed all night. We again had problems with the VME throughout the night (see problems section for details) but Jurek became quite adept at recovering from them and we managed to complete the linearity tests for 7 chips (z6, u2-u6, i2) compared to only one chip completed on the previous night (z5). ---=== IMAGING RUN SUMMARY ===--- Run Stripe Flavor Lambda Last Begin End Frame Comments ------------------------------------------------------------------ 2808 100 O ignore 143.56 150.96 63 2810 100 O ignore -155.51 -154.04 17 2811 100 O ignore -150.99 -149.85 22 ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot --------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields nGood rowMean rowSig colMean colSig rot --------------------------------------------------------------- ---=== SPECTROSCOPY DATA SUMMARY ===--- UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 23:31 12256 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument getclock Az Alt Rot Scale ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: none Stays: none ---=== 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 15:30 23 21 10 7 (N) 42 - tcl 16:01 22 21 22 336 (NNW) 807 - tcl 16:33 22 20 9 353 (NNW) 943 - tcl 17:05 22 20 13 349 (NNW) 8934 - tcl 17:35 21 19 18 344 (NNW) 59 - tcl 18:05 20 18 14 22 (NNE) 71 - tcl 18:35 19 17 22 14 (NNE) 70 - pcl 19:06 19 17 15 10 (N) 65 - clear 19:36 19 14 11 358 (NNW) 41 - clear 20:06 19 13 18 355 (NNW) 67 - clear 20:38 18 10 24 8 (N) 85 - clear 21:10 18 8 20 11 (N) 71 - clear 21:42 21 0 33 25 (NNE) 86 - clear 22:15 26 -7 26 28 (NNE) 36 - clear 22:47 32 -15 17 11 (N) 39 - clear 23:19 29 -13 26 18 (NNE) 50 - clear 23:50 30 -14 19 35 (NE) 64 - clear 00:23 31 -12 23 18 (NNE) 71 - clear 00:55 28 -8 15 24 (NNE) 70 - clear 01:27 31 -4 22 22 (NNE) 43 - clear 01:59 34 -8 22 18 (NNE) 48 - clear 02:31 35 -7 22 17 (NNE) 49 - clear 03:04 34 -3 22 27 (NNE) 27 - clear 03:36 32 -3 18 21 (NNE) 42 - clear 04:08 32 -3 26 30 (NNE) 35 - clear 04:41 33 -1 22 27 (NNE) 43 - clear ---=== TELESCOPE STATUS ===--- Never opened.
