APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday August 31, 2005 (MJD 53614) ---=== OBSERVING TEAM ===--- Swing: Jurek Krzesinski Night: Mike Harvanek Dan Long ---=== OBSERVING PLAN ===--- Plate 2247, then stripe 79 if imaging conditions. ---=== OBSERVING SUMMARY ===--- The mcp and TCC were put back on the public side after the mcp kept going unavailable when on the private side. The weather, aided at the start by a recalcitrant sop session, kept us from getting any science data. sop is still hanging quite frequently (even when Mike's driving). It seems to be related to, or at least exacerbated by running the guider code. SoS decided it didn't want to reduce flats. Unlike last night when it complained of missing plugMapM files, there were no complaints until it came to reducing frames which needed a reduced flat first. It just didn't reduce them. The flats were available on disk on SoS and the flavor in the header was flat. The rotator fiducial table has been updated to correct for the offset. instChange is now instChange! ---=== OBSERVING LOG ===--- Started out the afternoon with mcp and tcc on the private side. In the murmur log the mcp was complaining about not being able to write to mcpCmdLog (or even create /mcptpm/53614). 2005-09-01 00:55:57Z sdssmcp tCmdLog dsc_E_trcErr Can't create /mcptpm/53614: S_netDrv_UNIX_FILE_ERROR 2005-09-01 00:55:57Z sdssmcp tCmdLog dsc_E_trcErr Cannot open mcpCmdLog-53614.dat: S_netDrv_UNIX_FILE_ERROR This was fixed, but the mcp kept becoming unavailable and after a while even rebooting it did not bring it back to availability (being able to use the menu, or getting anything more than timeout on LTA19 when trying to use the TCC). Fritz decided at this point to put things back so that the TCC and mcp were both on the public side again. This gets the mcp to stay up and talk to the TCC, but alas means no positional info in imager frames. Oxygen sensor in pit started going off as soon as we opened. It was unplugged to keep scattered light down while observing (plugged back in when we closed). 01:00Z Doors Open, Fans On 02:50Z Enclosure Open Mike's sop session generated the following error trying to take a guider image: sp1> error writing file6: no route to host My session had no problem taking a frame. Mike restarted his sop and was then able to take a guider frame. 03:10Z Cartridge 3 2247 segue121 This is a bright plate with offsets for the brightest objects. guide stars on slew Instructions say to disable fibers 1, 4, and 7 for the fainter pointing. However there is a star in fiber 1. It isn't quite centered, so may be a coincidental alignment. In any case, disabled fiber 1. guiderFocus hung part way through. Mike ctrl-C'd out and it killed his murmur log windows which had been started from that sop session. I thought those were spawned and you could even exit the sop/iop session without affecting them. Further, upon starting new murmur windows, they brought up windows, but no data was going to them. Second guiderFocus completed (put up the plot) but never returned control to the sop session. Another ctrl-C, bye-bye murmur windows again. guiderGUI stopped accepting changes. A few minutes later, the guider stopped updating. Time for another ctrl-C. A scale change was made. After it completed the sop window became unresponsive again. Mike decided to try starting a new sop session. It came back with the following. sp1> initNight 2005-09-01 03:35:36Z: SOP Ready for flight I can't find rpc.pcnfsd running. You should do something!

Another ctrl-C. sop resumed guiding without further prodding. A short time later it stopped again. This time ctrl-C produced a traceback involving the guider. control-c while executing "error control-c" ("eval" body line 1) invoked from within "eval error control-c " invoked from within "if {$interrupt > 2} { set interrupt 0; echo level=[info level] ; eval error control-c }" while executing signal trap code for SIGINT signal invoked from within "gfindstars $guiderData(frame) $guiderData(fiberData)" (procedure "gunnCentroidGuideStars" line 31) invoked from within "gunnCentroidGuideStars $verbose" invoked from within "if {$haveGGuideData} { gunnCentroidGuideStars $verbose } else { foreach region $regionList { if {!$regionExists($region)} { murmur "Using ..."

It was around 125 with seeing of about 1.5 arcseconds about an hour ago. Now we are at -75 with seeing over 2.5 arcseconds. Granted, the temperature has gone up about 3 C in that time, but I would have expected a 50 micron change, rather than 200. Plate passes beyond availability before we can get any data :(. 04:50Z instChange 04:53Z Cartridge 8 2260 seguefaint121 Too cloudy to tell if we need FK5 or not. Going to one anyway. I guess it's too cloudy. Can't see FK5 either. 05:20Z Clouds thin enough to find fk5. It was just off the edge of the fiber. Setup slowly completed through significant cloud. 05:48Z preCalib Efficiency 20% or less. Waiting on start of science. SoS won't reduce 33728 (an arc) claiming it needs a flat. 33727 is both on sdssfiles1 and sos, and the header labels it as a flat. Don't know why SoS is refusing to reduce it (redo didn't help). Last night there was a similar complaint about needing a flat, but in that case there was also a warning about needing a plugMapM file to reduce the flat. No such warning tonight. Tried the ls from sdssfiles1 trick. No different. 06:10Z Increasing clouds, humidity, and uncomfortably close radar returns force us to close. Tried a postCalib in the enclosure to see if it would reduce that pair. Nope. 07:45Z Doors Closed, Fans Off (humidity) Rotator Fiducial Table ---------------------- While we were closed waiting on clouds, I implemented the rotator fiducial table with the .12 degree offset accounted for. instChange is now instChange! The canonical fiducial 78 had its value changed from 168185 to 188452. The magic incantation to plotMcpFiducials was plotMcpFiducials -mjd 53611 -rot -y pos1 -time0 1125325700 -time1 1125328185 -x fididx -canon -setCanon 78:188452 -reset -scale -table rot.dat Many thanks to Robert for the help on using plotMcpFiducials. 11:00Z endNight finished with rejoicing, apparently easily pleased by a couple unreduced postCals. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5553 00:18Z 00:54Z 100 O 54.04 62.98 71 ignore 5555 04:22Z 04:26Z 100 O 115.25 116.21 20 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):y QA Procedures Done (y/n):y UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 33712, plate -9999 ------- 01:27 33712 0.0 bias 01:50 33714 0.0 bias 01:53 33715 0.0 bias 01:59 33716 0.0 bias 02:02 33718 0.0 bias 02:06 33719 0.0 bias 02:33 33720 0.0 bias 02:36 33722 0.0 bias 02:39 33723 0.0 bias 02:44 33724 0.0 bias ----- sequence 33725, plate 2247 ------- 03:08 33725 0.0 bias ----- sequence 33726, plate -9999 ------- 03:39 33726 0.0 bias ----- sequence 33727, plate 2260 ------- 05:48 33727 10.0 flat 05:51 33728 2.0 arc 06:42 33729 10.0 flat 06:45 33730 2.0 arc ----- sequence 33731, plate 2247 ------- 08:31 33731 10.0 flat 08:34 33732 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 05:46Z 8 2260 44.27 -0.0019 74.92 0.0017 218.88 -0.0954 0.999980 ---=== 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 ------------------------------------------------------------------------------ 03:01Z 3 2247 1.00000 0 1280 0 121 30.0 12.9 18 74 03:42Z 3 2247 1.00005 -494 860 125 240 63.6 14.1 11 80 - 2.5 05:46Z 8 2260 0.99998 198 1187 -100 44 74.9 15.2 10 96 - 1.7 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 00:52Z 60 47 13 79 (E) -9999 - Mostly Clear 01:25Z 58 47 15 76 (ENE) -9999 - Clear 01:58Z 56 47 18 74 (ENE) -9999 - Mostly Clear 02:33Z 55 46 15 78 (ENE) -9999 - Mostly Clear 03:05Z 55 46 15 80 (E) -9999 - Partly Cloudy 03:40Z 57 41 12 88 (E) -9999 - Partly Cloudy 04:13Z 59 36 12 93 (E) -9999 - Mostly Cloudy 04:45Z 59 34 13 79 (E) -9999 - Mostly Cloudy 05:16Z 59 37 11 94 (E) -9999 - Mostly Cloudy 05:46Z 59 37 10 95 (E) -9999 - Partly Cloudy 06:20Z 56 48 11 92 (E) -9999 - Mostly Cloudy 06:54Z 57 44 16 126 (SE) -9999 - Mostly Cloudy 07:26Z 56 47 11 107 (ESE) -9999 - Mostly Cloudy 07:58Z 56 48 7 89 (E) -9999 - Cloudy 08:31Z 56 47 8 73 (ENE) -9999 - Sprinkles 09:03Z 58 42 4 94 (E) -9999 - Cloudy 09:35Z 60 39 5 194 (SSW) -9999 - Cloudy 10:07Z 60 39 5 181 (S) -9999 - Mostly Cloudy 10:39Z 58 41 9 128 (SE) -9999 - Mostly Cloudy ---=== TELESCOPE STATUS ===--- 01:00Z Doors Open, Fans On 02:50Z Enclosure Open 06:10Z Enclosure Closed, Doors Cracked, Fans On 07:45Z Enclosure Closed, Fans Off Stowed at 30 deg alt, cartridge 8 installed.
