Data located in /export/images/Q4APO/UT101222/Shutter_tests/) Checked Russet's new pointing script Implemented pointing model taken earlier Took out of focus images for both SPIcam and AGILE. -1500 to +1500 in steps of 300. Data can be found in /export/images/Q4APO/UT101222/SPIcam_Collimation and Agile_Collimation. Disregard first set of SPIcam images (1-11) and first Agile image (1). Collimation check, adjusted and used Russet's new script to correct pointing model. Checked pointing at the Echelle and corrected. Used Russet's new script. Focus image sweep again with SPIcam & Agile (Post collimation adjustment) Same location as above with _post added to filenames. DIS Throughput measurements Fastcam data collection wrt000alt060 09:37:00UT Monitoring the FPS I noticed that during exposures with Fastcam the data rate appeared to fluctuate from 40-100 fps. (I screwed up and had it recording files instead of a sequence, my bad) wrt045alt60 10:04:30UT (this one is a sequence and recorded at 100fps) wrt000alt60 10:24:30UT wrt090alt60 10:49:00UT wrt180alt60 11:11:00UT wrt000alt60 11:38:00UT Completed all engineering tasks on the list tonight. Clouds were starting to get thicker around 05:00. ------- 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 -------------------------------------------------------------------------- 17:50 GUIDER 328( 59) -11 52 3.9 5.4 4.5 4.2 4.5 R 1.15 19:31 GUIDER 145( -133) 264 22 4.4 4.2 4.5 3.9 4.3 R 1.30 20:09 SPICAM -4( -343) -6 58 4.7 4.2 4.5 3.7 4.3 MSSSO V 1.26 21:12 AGILE -1550(-2470) -33 54 5.3 4.5 4.9 4.3 4.7 r' 0.76 22:17 SHACK -75( -6) 64 65 4.7 4.5 4.8 4.3 4.4 -- 1.00 23:26 ECHELLE 118(-1422) 25 76 4.3 4.3 4.7 4.0 4.2 ND2 0.64 23:54 SPICAM 42( -289) 2 57 4.8 4.3 4.7 3.9 4.3 MSSSO V 0.61 01:06 dis-slit 261( -319) 218 61 5.0 4.4 4.8 4.1 4.5 -- 0.89 02:16 FASTCAM 100( 207) 115 57 4.3 4.1 4.2 3.7 3.9 -- 0.98 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 44 25 15 263 (W) 209 clear none 17:00 41 27 15 266 (W) 308 clear none 18:00 39 25 8 221 (SW) 249 clear none 19:00 40 25 9 264 (W) 279 clear none 20:00 39 24 10 259 (W) 324 clear none 21:00 41 27 14 288 (WNW) 385 clear none 22:00 41 27 13 287 (WNW) 413 clear none 23:00 40 27 10 292 (WNW) 434 clear none 00:00 41 27 12 258 (WSW) 476 clear none 01:00 41 26 13 252 (WSW) 459 mstly clr none 02:00 39 26 11 205 (SSW) 451 mstly clr none 03:00 41 25 14 235 (SW) 415 ptly cldy none 04:00 41 25 13 219 (SW) 405 ptly cldy none 05:00 40 23 12 216 (SW) 309 ptly cldy none Note: the wind was coming from the azimuth listed.
