APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday February 16, 2006 (MJD 53783) ---=== OBSERVING TEAM ===--- swing: Jurek Krzesinski night: Mike Harvanek, Elena Malanushenko, Viktor Malanushenko support: Steph Snedden, Craig Loomis (by phone), Kurt Biery (by phone), Eric Neilsen (by phone). ---=== OBSERVING PLAN ===--- Shakedown and science, if possible. ---=== OBSERVING SUMMARY ===--- Obtained good data on 1 plate (1246). Most of the night lost to clouds then dust at the end. Did the following shake items: Successfully tested spectrographs on the sky. Tested DA successfully - status of 4 relevant PRs is still pending as we are checking for normal DA behavior during regular operations. Is there no sd2 VxWorks board? Tested endNight successfully - PRs 6720 and 6750 closed. Verified changes in sdssProcedures v2_11. Verified DAS objects appeared in the PT manual targets list. Shake items not completed: Imager testing on-sky (cloudy for most of the night). PR 6868 - will test with imager on-sky. IOP v4_18_0a still test - successful so far but needs more testing. The rotator offset is back. The mcp crashed tonight. There was some weird behavior with the flat field lamps. See the main log section for more details on these items. Lateral E and F primary mirror nominal values appear to have changed since the last dark run. When we get on the sky with the imager and verify collimation is okay we will reset these values. The mcpMenu option on the pulldown menu on sirrobert no longer works. ---=== OBSERVING LOG ===--- Afternoon checkout: ------------------- while stopping the drift we saw the folowing error: 2006-02-16 22:24:51Z: Error stopping focus loop: couldn't open "/astrolog/53783/focus-53783.par": Permission denied 2006-02-16 22:24:55Z: stopping drift with: iccExec id1 id2 id3 id4 id5 id6 ad1 ad2 ad3 ad4 readoutEnd quick check on the file and we see cloomis owns it. We changed the permissions and proceeded. Rotator: It seems that MCP commanded and shown positions are different. When we moved the rotator in a positive direction, MCP was showing always something short than commanded value by 2-10". When moved negative direction it was showing more than commanded by 3-10". Even when commanded positions were the same MCP was showing different offests from that position. For commanded 0 for example, MCP was showing 0:0:3.5" up to 0:0:10". Craig and Steph are investigating if that might be connected with PID loop value change. Here is what Steph found: A comparison of the old and new PID coefficients: P I D Old values 120 12 600 New Values 120 4 350 (installed January 10) Craig cleverly pointed out that lowering the integral coefficient could be the problem. If lowering the I coefficient makes the error filter broader, that would certainly fit the problem we are seeing. Steph is looking for a log or record of PID values in use on the date that the fiducial data was gathered, but so far has had no luck. Lateral E, F primary mirror values are not the same as during the last dark run. Was this due to a battery change? When we get on the sky with the imager and verify that the collimation is good we will reset the nominal values. Night: ------ We start with the spectrograph checkout by trying to do some real science. Plate 1246 (cartridge 8): Orion. The gflat on the gotoField failed. It appears that only 3 of the 4 flat field lamps are lighting. We go down to the telescope to investigate but all the lamps light up down there. We cycle the lamps on and off several times but all 4 lamps light every time. Okay. French was notified when he called to check in around 02:30Z. We also had to reset the guider mac from the engcam to the guider after we noticed that gcam was failing. Finally got everything working around 02:35Z. We obtained one useful science frame and an offset frame. The second science frame was declared bad due to low S/N^2 (clouds) and so the second offset frame was aborted. By this time the plate had expired and the moon was coming up so we took a postCal as requested and moved on to other shake tasks. Note that SoS gave a few max sky residual warnings. A summary of the exposures for this plate is given below: exposure # exposure time purpose guided seeing or offset ---------- ------------- ------- ------ ---------------- 37477 1500 sec science yes 1.5" 37478 1500 sec sky no +9" in RA 37479 1200 sec science yes 2.1 - 3+", S/N < 2, declared bad We called Kurt Biery and had him on the phone while we did some DA testing. Everything looked good but we will wait to see that the DA behaves normally during regular operations before we change the status of the relevant PRs. Note that we examined photo, spectro and mt frame headers and photo gang headers and everything appeared to be okay. We also checked for the monitor files in /linuxp/astrobase/monitorOutput and found 12 such files appearing hourly (approximately). Is there no sd2 board? The sky was still totally overcast but the satellite images showed a small break in the clouds was approaching. So, we mounted the imager so we'd be ready to go when the break in the clouds arrived. While checking the balance after mounting the imager, the mcp crashed (05:43Z?). We rebooted it twice. Note that the mcpMenu option from the drop down menu on sirrobert no longer works. To open up an mcpMenu on sirrobert you must now do it from an xterm on host2. The break in the clouds never arrived and we put the enclosure on around 06:30Z due to increasing clouds. We continued to ventilate the enclosure, however. While waiting for the clouds to pass we examined this month's changes to sdssProcedures (v2_11). The "Preliminaries" section of pointing1.html was checked and found to be okay. Note that the computer commands in this section are now in boldface. pointing1.html is still under revision. In the IOP section of swInstall.html, IRIX+6 has been replaced with Linus+2.4 and the mop installation procedure has been replaced with a note stating that mop is now managed as part of IOP. Several small changes to shakes.html were also verified. The dust counts started to rise and we closed up around 12:05Z. We then tested both of the endNight PRs (6750, 6720). Both were successful and both PRs were closed. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6019 22:05Z 22:26Z 100 O -172.86 -167.61 49 ignore 6020 22:32Z 22:42Z 100 O -166.10 -163.58 31 ignore 6021 22:54Z 23:03Z 100 O -160.54 -158.23 29 ignore 6022 04:27Z 04:42Z 100 O -76.89 -73.36 38 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): YES QA Procedures Done (y/n): YES UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 37471, plate -9999 ------- 22:04Z 37471 0.0 bias 23:04Z 37472 0.0 bias 01:05Z 37473 0.0 bias ----- sequence 37474, plate 1246 ------- 7.1 4.8 10.9 7.7 not done 01:49Z 37474 0.0 bias 02:40Z 37475 10.0 flat 02:42Z 37476 2.0 arc 03:11 37477 1500.1 target science 03:39 37478 1500.1 target sky - offset in RA = +9 04:03 37479 1200.1 target bad - low S/N^2 04:12 37480 10.0 flat 04:14 37481 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 02:48Z 8 1246 5.49 -0.0032 57.07 0.0036 184.54 -0.0106 1.000290 ---=== 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 ------------------------------------------------------------------------------ 02:48Z 8 1246 1.00029 -2864 -1035 175 6 57.1 3.5 14 256 ---- 1.4" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 02:01Z 36 0 13 256 (WSW) 1150 - partly cloudy 02:34Z 38 -3 13 259 (W) 668 - 03:05Z 38 -3 18 251 (WSW) 671 - 03:36Z 39 -2 18 234 (SW) 623 - 04:06Z 39 -1 12 222 (SW) 711 - mostly cloudy 04:38Z 40 0 7 182 (S) 778 - 05:10Z 35 -3 10 182 (S) 798 - 05:40Z 41 -1 17 179 (S) 674 - 06:11Z 41 -1 14 190 (S) 661 - 06:41Z 40 0 15 185 (S) 669 - 07:11Z 40 0 18 190 (S) 689 - 07:41Z 40 0 18 194 (SSW) 686 - 08:11Z 39 1 17 190 (S) 815 - 08:41Z 39 2 17 188 (S) 791 - 09:14Z 39 1 24 200 (SSW) 979 - 09:46Z 39 2 19 209 (SSW) 874 - 10:18Z 39 3 19 197 (SSW) 1188 - 10:50Z 39 3 23 197 (SSW) 1063 - 11:22Z 37 2 23 194 (SSW) 1925 - 11:55Z 37 3 23 199 (SSW) 2705 - 12:27Z 35 3 18 190 (S) 3911 - high dust 12:59Z 37 4 28 201 (SSW) 1615 - 13:33Z 38 5 29 208 (SSW) 1122 - ---=== TELESCOPE STATUS ===--- ??:??Z Enclosure doors opened, fans and blowers on, louvers opened. 01:30Z Enclosure off. 06:30Z Enclosure on (clouds) but still ventilating. 12:05Z Doors closed, fans and blowers off, louvers closed.
