TUI was running really sluggish during checkout and I couldn't get echelle slitviewer to take any images. After trying what Fritz suggest in private email from earlier in the day, I called Fritz to figure out why things were running slow and if it was affecting the echelle slitviewer. He rebooted tron as the connection for the tcc guider (echelle slitviewer) was cuasing the problems. That fixed things. slitviewer quit, taking another exposure fixed it. log dump below for details 09:29:16 APO.Jack-Obs1.ecam 4436 ecamera f text="could not read new image file: stat() argument 1 must be (encoded string without NULL bytes), not str" 09:29:16 CmdDone: client-21 4436 ecamera expose exptime=3.0 bin=1,1 offset=0,0 size=511,511 filename=/export/images/ecam/UT111019/e0842.fits 09:29:16 APO.Jack-Obs1 272 ecam i camFile="None" 09:29:16 APO.Jack-Obs1 272 ecam i guideMode="boresight"; guideState="stopping","" 09:29:16 APO.Jack-Obs1 272 ecam i guideMode="boresight"; guideState="off","" 09:29:16 APO.Jack-Obs1 272 ecam f text="text=\"could not read new image file: stat() argument 1 must be (encoded string without NULL bytes), not str\"" 09:29:16 CmdDone: APO.Jack-Obs1 272 ecam guide on boresight exptime=3.0 bin=1 window=0,0,510,510 radMult=1.0 thresh=2.5 imgFile='ecam/UT111019/proc-e0719.fits' My observer also noted that the guider tended to hang tonight while the echelle was flushing. It did this on several occasions. TSPEC vacuum looked good all night Letf TSPEC mounted since observer needed to do morning cals. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 19:19 ECHELLE 392( -887) 58 69 5.6 9.2 8.3 8.6 6.1 ND3 1.00 01:09 ECHELLE 361(-1176) 236 39 4.5 3.5 3.9 3.3 3.7 ND3 0.75 04:43 TSPEC 392( 41) 30 67 4.3 2.9 3.4 2.8 3.3 Ks 1.00 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 50 22 9 263 (W) 1010 clear none 17:00 49 22 3 252 (WSW) 838 clear none 18:00 47 21 6 255 (WSW) 604 clear none 19:00 42 20 1 313 (NW) 600 clear none 20:00 41 21 12 30 (NNE) 796 clear none 21:00 42 20 9 345 (NNW) 962 clear none 22:00 41 21 6 323 (NW) 806 clear none 23:00 40 21 6 315 (NW) 586 clear none 00:00 39 21 3 308 (NW) 530 clear none 01:00 40 21 5 353 (N) 609 clear none 02:00 39 21 6 339 (NNW) 585 clear none 03:00 39 21 8 320 (NW) 585 mstly clr none 04:00 38 21 6 328 (NNW) 630 mstly clr none 05:00 40 21 8 317 (NW) 690 mstly clr none 06:00 40 21 9 305 (NW) 959 mstly clr none Note: the wind was coming from the azimuth listed.
