I focused and noticed that the pointing was off in the slitviewer, so I did the NA2Point that Russet suggested yesterday. The Y tilt was off about -182, I didn't adjust the X. Heather reported that the pointing was near spot on. I also discovered that the offsets in given in slitview (using c) need to have the X axis sign reversed when entered into TUI Offset. I warned Heather about this. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEGDFVO) TI/SHU START FINISH DESCRIPTION ----------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Air/Truss Wind Time Instrument Focus Az El Temp-C Dir MPH filt FWHM --------------------------------------------------------------------- 23:18 DISslit -90(906) 109 61 3.1/4.6 289 17 none 1.13 23:27 NA2gdr -2263(44736) 111 63 3.4/4.3 301 17 clear 1.17 01:01 DISslit 60(1042) 337 47 2.9/3.1 292 18 none 1.47 01:06 NA2gdr -2596(44403) 336 47 2.8/3.1 300 23 R 1.26 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:01 48 29 30 226 (SW) 611 Cloudy none 17:01 44 24 22 228 (SW) 594 Cloudy none 18:01 44 25 26 237 (WSW) 722 Cloudy none 19:01 43 21 21 268 (W) 712 Cloudy none 20:01 41 21 16 266 (W) 740 Cloudy none 21:01 39 27 12 297 (WNW) 1475 Cloudy none 22:01 39 27 13 269 (W) 818 Pt.
