The first program had no isues but we struggled with the second program. Since TSPEC slitviewer isn't working, we were attmepting to convert gam star position to tcam slit position. However, we noticed the star had a large offset when we did not enhace a large offset. Russet saw that the C actuator on the secondary mirror had moved 60 steps. She homed the mirror, which solved the problem, but it did take us some time to find where the tcam slit position mapped onto gcam. At the end of the night, the nightlog would not submit. While I tried to email the file, I was never given the "success" window and then the nightlog crashed. I'm having to send this via my email. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- WY02 Tspec T/H 01:18 01:50 Secondary mirror homed WY02 TSPEC T/S --:-- --:-- 0.75hr for extra time to position star in tcam ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 23:45 ecamera 456( 76) -115 60 10.6 10.0 10.6 10.1 10.1 clear 1.34 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 54 1 20 222 (SW) 1581 mstly cldy none 17:00 53 4 21 235 (SW) 1468 mstly cldy none 18:00 53 4 18 209 (SSW) 1435 mstly cldy none 19:00 54 6 21 239 (WSW) 1915 ptly cldy none 20:00 51 4 22 217 (SW) 2010 clear none 21:00 52 5 24 214 (SW) 2431 clear none 22:00 51 5 16 226 (SW) 2454 clear none 23:00 51 4 14 262 (W) 2094 clear none 00:00 51 4 12 255 (WSW) 1638 clear none 01:00 50 5 22 266 (W) 1531 clear none 02:00 50 6 12 266 (W) 1507 clear none 03:00 49 5 5 297 (WNW) 1438 clear none 04:00 48 4 10 276 (W) 1482 clear none 05:00 46 4 8 307 (NW) 1653 clear none 06:00 44 5 0 312 (NW) 1689 clear none Note: the wind was coming from the azimuth listed.
