APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday August 9, 2001 (MJD 52131) ---=== OBSERVING TEAM ===--- Daniel Long Eric Neilsen Steph Snedden (day) Scot Kleinman Pete Newman (PT training) ---=== OBSERVING PLAN ===--- More Shakedown. Same as last night since weather kept us closed. Verify pointing model, put on cartridge and test spectroscopy, test bd17smear. Put on imager, test drift scanning, test bright star code. ---=== OBSERVING SUMMARY ===--- We were only open long enough at the start of the night to focus the engineering camera. Yes, just like last night. Pete got some PT training as well. ---=== OBSERVING LOG ===--- Afternoon shake tasks: ---------------------- During the afternoon, Steph tested Connie's multi-lskip code. She let the lskips run for about 75 frames. There appeared to be no problems with the code, and the lskips continued throughout the bias drift. We should be in good shape to do the bright standards test. The imager "panic button" was also tested. We got the expected critical errors (phase_boot and exec_boot). The imager was iack'ed and the voltages set to operating values. A subsequent bias indicated that all was well with the CCDs. The evening was spent training Pete on the PT. We note that with redHat 7.1, you should no longer 'startx -- -bpp 8', but should 'startx -- -depth 8'. Thanks for that info, Eric. A request was made to have the PT procedures updated to reflect the change. To handle the ssh stuff at the start as well the full command should be 'ssh-agent startx -- -depth 8'. During the afternoon checkout the engcam was found not to be talking. The power supply for the camera was found to be switched off. In the process of finding the problem, Craig noticed that the delay was delaying the wrong piece of equipment. The parallan was plugged into the delay. What needed to be delayed was the A2S. The appropriate power cables were swapped, and the power up sequence tested. We got an image back on the first try. It looks like the work on the M2 galil today fixed the E actuator problem. There were no full step complaints when the mirror was checked out and it continued to work the rest of the night ( well at least until 21:30 when we closed due to weather ). Like last night we opened shortly after sunset under promising skies, especially given the forecast. Also like last night we only got as far as focusing the engineering camera and getting to the first point of a small pointing model to test the one taken on Monday before it clouded over and we had to close. Clouds and occasional rain remained with us the rest of the night. Tonight, and the previous three times this week when I started a pointing model, dopterr elicited the complaint that the TCC didn't have the semaphore. This is strange considering the telescope was tracking and had been told to do so by a TRACK command from the TCC. Issuing an axis init from the telrun session and then trying the dopterr again works. It isn't clear whether this is a TCC or MCP problem, but since I saw the error in telrun I filed the PR under 2.5m-tcc. See PR 2563 and/or the problem section for details. When running endNight one of the tapes in the drive was not a normal data tape. A backup tape for sdsshost was in the left hand drive when endNight was run. This is only bad news in the sense that the backup may have been compromised. Since there was no data from tonight which actually needed to be archived, the tapes would have been recycled anyway ( endNight was being run simply to copy various logfiles to skycat/oplogs ). Sadly you can't just run endNight -copy without sending things to tape. ---=== IMAGING RUN SUMMARY ===--- Run Stripe Flavor Lambda Last Begin End Frame Comments ------------------------------------------------------------------ 2481 100 O ignore 44.62 48.24 36 ---=== 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 ----- sequence 10519, plate -9999 ------- 01:22 10519 0.0 bias {{}} ----- sequence 10519, plate -9999 ------- 01:22 10519 0.0 bias {{}} ----- sequence 10519, plate -9999 ------- 01:22 10519 0.0 bias {{}} ----- sequence 10519, plate -9999 ------- 01:22 10519 0.0 bias {{}} 01:29 10520 0.0 bias {{}} 01:29 10520 0.0 bias {{}} 01:29 10520 0.0 bias {{}} 01:29 10520 0.0 bias {{}} ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument getclock Az Alt Rot Scale ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL Stays: JL ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 21:01 engcam 1.00000 0 -2731 -375 87 63.4 14.3 10 182 nd2 1.0 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 17:00 67 44 15 219 (SW) 583 - Partly Cloudy 17:32 64 43 16 212 (SSW) 630 - Partly Cloudy 18:00 64 43 15 205 (SSW) 564 - Partly Cloudy 18:29 59 43 10 209 (SSW) 607 - Partly Cloudy 19:01 59 44 11 207 (SSW) 680 - Partly Cloudy 19:30 58 44 9 208 (SSW) 677 - Partly Cloudy 20:02 57 44 5 184 (S) 733 - Mostly Clear 20:31 57 43 6 187 (S) 753 - Partly Cloudy 21:07 57 43 8 181 (S) 685 - Mostly Cloudy 21:39 58 42 11 181 (S) 624 - Mostly Cloudy 22:11 58 42 8 180 (S) 662 - Cloudy 22:43 57 43 5 181 (S) 617 - Cloudy 23:16 55 45 16 131 (SE) 750 - Cloudy 23:48 54 46 11 114 (ESE) 1079 - Cloudy 00:20 54 46 11 112 (ESE) 953 - Cloudy 00:52 53 46 8 110 (ESE) 1069 - Cloudy 01:24 52 48 16 180 (S) 1066 - Light Rain 01:57 50 50 10 153 (SSE) 100 - Fog 02:29 49 49 10 146 (SE) 668 - Fog 03:01 49 48 14 157 (SSE) 799 - Cloudy 03:37 49 48 16 152 (SSE) 885 - Cloudy 04:09 50 48 17 143 (SE) 876 - Cloudy 04:42 50 46 17 134 (SE) 524 - Cloudy 05:14 51 46 16 154 (SSE) 618 - Sprinkles ---=== TELESCOPE STATUS ===--- Stowed at 30 deg alt, engcam installed.

This is after the telescope has been slewed via telrun and is currently tracking. If you then issue an axis init in the telrun session, then reissue the dopterr command, it works without complaint. What follows is the response in the telrun session to running dopterr as first described. 0 0 : Text="pointing error log file opened" 0 0 > Started; Cmd='Track/Wait -47.75, 42.25 Mount' 0 0 W Text="some axes will not be slewed"; AxisNoSlew="FFT" 0 0 I TCCStatus="TTT","NNN"; TCCPos=86.21,64.32,71.71; AxePos=86.21,64.33,71.71 0 0 I ObjNetPos = -47.750000, 0.000000, 4504129548.01000, 42.250000, 0.000000, 4504129548.01000 0 0 I ObjInstAng = NaN, NaN, NaN 0 0 I SpiderInstAng = NaN, NaN, NaN 0 0 F Modu="prt_ReadReplySet"; Text="too many replies on port LTA19:" 0 0 I Modu="prt_ReadReplySet"; Text="the following replies were read:" 0 0 I Modu="prt_ReadReplySet"; Text="ERR: I don't have the semCmdPort semaphore" 0 0 F Modu="prt_ReadReplySet"; Text="too many replies on port LTA19:" 0 0 I Modu="prt_ReadReplySet"; Text="the following replies were read:" 0 0 I Modu="prt_ReadReplySet"; Text="ERR: I don't have the semCmdPort semaphore" 0 0 F Modu="prt_ReadReplySet"; Text="too many replies on port LTA19:" 0 0 I Modu="prt_ReadReplySet"; Text="the following replies were read:" 0 0 I Modu="prt_ReadReplySet"; Text="ERR: I don't have the semCmdPort semaphore" 0 0 F Modu="axe_o_NoAbsRefCorr"; Text="could not disable absolute encoder correction for AZ , ALT, ROT" 0 0 W AxisNoTrack="TTT" 0 0 I AxisStop="TTT" 0 0 F Text="move failed; axes halted" 0 0 > Started; Cmd='Pterr Close' 0 0 I Modu="exe_DoPtErr"; Text="Pointing data collection ends" 0 0 : Text="pointing error log file closed" This happened shortly before getclock 997412787 or about 21:05 local time. I leave it to Russell and Robert to determine if this is a TCC or MCP bug. It isn't a show-stopper in any way, but a minor nuisance, and a curious bug. This has happened each of the three times I have issued a dopterr command during this shakedown.
