APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday May 2, 2005 (MJD 53493) ---=== OBSERVING TEAM ===--- Swing: Dan Long Night: John Barentine Jurek Krzesinski ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Plates done: 2012,2001,2088,1575,2132, partial signal on plate 1837 We tried imaging, but immediately after we swapped instruments the seeing got bad and stayed variable for the rest of the night. problems: --------- The seeing KNOWS when we change to imaging, should be an easy fix. The hose to pressurize imager cart is broken. Could someone fix it please? We left it in the engineering trailer. Spectro displays got frozen. We did not reboot the spectro crate, because files still were transfered and stored on the disk. Several guider frames did not arrived tonight, we had to repeat the guide commands. sop error - probably connected with backup relay server, see the problem section. ---=== OBSERVING LOG ===--- Afternoon: ---------- One problem with the afternoon check. The azimuth fiducials did not register any crossings in several sweeps between 80 and 160 degrees. Wiping off the read head with isopropyl alcohol got them working again. Thanks to JB for the suggestion to use isopropyl, a dry cloth just doesn't cut it. Spectrograph focus checked and found to be in focus for current ambient. Adjusted to compensate for cooler predicted temperatures overnight. Last night focus was adjusted (as well as positional parameters - a little sad as all were adjusted into spec during monthly checkout only five days ago). The temperature at the time was just under 8 C. Assuming the spectrographs were in equilibrium with the air temp (a good bet considering the telescope had been ventilating for more than 6 hours waiting on clouds) the 2000 subtracted this afternoon should set them for 6 C. It should be noted that sp1 is currently set about 3 degrees warmer (3000 steps) than sp2 based on the spectro monthly starting point. See problems section for details. Night: ------ 02:24Z cart 3 plt 2088 on the telescope. It's too bright, so we used fk5 to find the guide stars. While waiting for the sky to get dark, we've done precalibs and found flat's r2 xsigma in yellow. Since that indicates spectrographs being out of focus, we've done Hartman exposures and indeed (M1 temp ~5.8C), both sp1 and sp2 were out of focus: sp1> COLLIMATE: Mean offset = -0.43 pix r1 sp2> COLLIMATE: Mean offset = -0.59 pix r2 So we pistoned them appropriately ~4000 (see the problem section). Flats became ok., arc fine (wavemin for r2 became yellow). We lost 10 minutes of good twilight time but started an exposure 5 minutes before twilight end. Postal recomended and taken. Plate done. SOS warnings: Median wavelength widths. 04:17Z cart 1 plt 2012, GOGTF. By a mistake we started the science exposure before precalibing. Precalib taken after that exposure and reduction redone, but first attempt to take precalib, resulted in error: flat exposure too faint... (maybe petals did not close on time?). The second precalib exposure started ok., but then spectro DA refused to display them. Since goStare seems to work anyway and exposures are stored on the disk, we proceeded with observations blindly (no show of spectra on the displays). Plate done. SOS warnings: Max sky-residual. 05:30Z cart 2 plt 2001. fk5 used. Arc r1: wsigma is yellow (~3.8 C). plate done. SOS warnings: none. Clouds are all around us, but there was a clear hole above APO, which was stable for about 2 hours (photometric). We decided to mount the imager. Seeing was ~1.3". 06:44Z While slewing to the stripe, the tcc command timed out. 06:45Z Run 5301, stripe 18, N, the telescope slewed to lambda 7. Seeing good since the beginning. Stars seems to be horizontaly elongated, but skippy says we are well in spec :). Frame 24 lambda 10 deg - beginning of the ramp. Hmm the seeing got worse, still climbing. frame 38, lambda 12 - beginning of the science in bad seeing conditions :(. 07:35Z There is no hope that the seeing will improve. We gave up with imaging after 50 minutes of drifting. None of iop skippy result showed in the nightlog. Fortunately astrom worked fine... but for nothing. 07:35Z cart 4 plt 1575 mounted. SOGTF. Seeing is variable. Precalibs showed in yelow (wsigma, xsigma for b1,r1). Plate done. Asked for postcalib on the first exposure, which we ignored. SOS warngings: none. 08:42Z cart 7 plt 2132 mounted. fk5 used. Guider frame did not returned on time (again). The temperature had changed from 2.5 C - 5 C, instead of nice stars in the fibers, we saw donuts. Focus sweep was done. Clouds arrived. Our efficiency is still good enough to get some signal. Flat r1 xsigma, arc b1,r1 wsigma in yellow. We've got sop error after we sucessfuly started the exposure, which might be connected to the backup realy server (see the problem section). Plate done. SOS warnings: Max sky-residual. 10:07Z cart 9 plt 1837 mounted. SOGTF. Precalibs: flat r1 xsigma and arc b1,r1,r2 wsigma in yellow. 2 exposures done. In twilight we took Hartman exposures to see how far off we were from focus, when sos showed yellow xsigma/wsigma (on the last plate), temp: ~4 C. The resutls are below (hartman exposures 32487,32488): b1> COLLIMATE: Mean offset = -0.43 pix b2> COLLIMATE: Mean offset = -0.45 pix r1> COLLIMATE: Mean offset = 0.60 pix COLLIMATE: Issue SOP command: "sp1; mechPiston -5505" r2> COLLIMATE: Mean offset = 0.48 pix COLLIMATE: Issue SOP command: "sp2; mechPiston -4400" So, whatever we pistoned at the beginning of the night, now we would have to retract. We DID NOT issued required piston commands, so actuator positions are like those listed in the problem section. endNight done. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5301 06:45Z 07:34Z 18 N 7.40 19.66 95 science bad ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- no iop skippy result showed up here, so we cut the results from astrom: frame 30, 5 frames: ------------------- THETAF = -0.0033 degrees, -12.06 arcsec CT = 0.39598 arcsec/pixel SCALEF = 16.5970 arcsec/mm AMU0 = 195.5984 degrees ANU0 = 0.0008 degrees NCAT = 58 NSTARS = 43 AZ = 244.1626 degrees EL = 65.0013 degrees raBoreErr: -6.1", decBoreErr: 3.3" azErr: 14.4", elErr: -2.6" muErr: -5.9", nuErr: 2.9" Correct idReport boresight values: xBore = -22.92 mm, yBore = 0.36 mm. ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ 5301 77 1 65 298 9 -0.351 0.097 -0.719 0.127 0.00242 5301 77 1 65 298 11 -0.407 0.100 -1.166 0.330 0.00392 5301 77 1 65 298 12 -0.093 0.242 -1.074 0.221 0.00361 5301 77 1 65 298 8 -0.090 0.127 -0.904 0.242 0.00304 5301 77 1 65 298 5 -0.198 0.291 -1.398 0.285 0.00470 ---=== 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 22:27 32449 2.0 arc ----- sequence 32450, plate -9999 ------- 01:29 32450 0.0 bias 02:09 32451 0.0 bias 02:17 32452 0.0 bias ----- sequence 32453, plate 2088 ------- 02:43 32453 10.0 flat 02:45 32454 2.0 arc 02:52 32455 2.1 arc 02:54 32456 2.1 arc 03:07 32457 10.0 flat 03:09 32458 2.0 arc 03:31 32459 900.1 target 03:49 32460 900.1 target 04:04 32461 720.1 target 04:07 32462 10.0 flat 04:10 32463 2.0 arc ----- sequence 32464, plate 2012 ------- 04:41 32464 900.1 target 04:49 32465 10.0 flat 04:51 32466 2.0 arc 05:10 32467 900.1 target 05:23 32468 600.1 target ----- sequence 32469, plate 2001 ------- 05:39 32469 10.0 flat 05:42 32470 2.0 arc 05:55 32471 600.1 target 06:13 32472 900.1 target 06:26 32473 600.1 target ----- sequence 32474, plate 1575 ------- 07:57 32474 10.0 flat 08:00 32475 2.0 arc 08:20 32476 900.1 target 08:34 32477 600.1 target ----- sequence 32478, plate 2132 ------- 08:59 32478 10.0 flat 09:02 32479 2.0 arc 09:22 32480 900.1 target 09:40 32481 900.2 target 09:58 32482 900.2 target ----- sequence 32483, plate 1837 ------- 10:14 32483 10.0 flat 10:16 32484 2.0 arc 10:37 32485 900.1 target 10:55 32486 900.2 target 10:59 32487 2.1 arc 11:02 32488 2.1 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 02:38Z 3 2088 114.32 -0.0004 55.33 0.0020 -91.83 -0.0033 1.000300 05:07Z 1 2012 252.72 -0.0013 75.64 0.0022 82.25 0.0091 1.000190 07:34Z imager 297.95 0.0000 64.91 0.0000 45.06 0.0000 1.000000 07:57Z 4 1575 51.96 -0.0048 78.83 -0.0005 227.09 0.0337 1.000000 10:11Z 9 1837 -48.66 -0.0002 51.94 -0.0003 140.57 -0.0095 1.000000 10:42Z 9 1837 -57.48 -0.0001 46.70 -0.0001 134.52 -0.0116 1.000000 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL8477 Stays: JL8478 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 02:38Z 3 2088 1.00030 -2961 -1277 10 114 55.3 6.0 6 265 gdr 1.4 05:07Z 1 2012 1.00019 -1875 -370 60 253 75.7 4.4 3 192 gdr 1.3 07:34Z imager 1.00000 0 -286 -162 298 64.9 3.2 9 171 07:57Z 4 1575 1.00000 0 1212 92 52 78.8 3.2 6 181 gdr 1.5 10:11Z 9 1837 1.00000 0 1138 -36 -49 52.0 3.9 12 182 gdr 1.5 10:42Z 9 1837 1.00000 0 1229 38 -57 46.7 4.1 10 177 gdr 1.5 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:28Z 44 31 4 277 (W) 395 -
