Separate email on findings sent to necessary parties. biggrid pointing model. Made sure the PZZ1 gone and IE set to 0 tonight. spot checked with several stars on NA2, looked good. Checked pointing at NA1, looked good. Adjusted DIS boresight in configuration file so better centered for 1.5 arc sec slit. Grabbed a few more throughput observations Slitviewer vs. DIS spectrograph focus 90s exposure 0.9 arc sec slit Star BD28 DIS slitviewer focus 564 @ 1.02 arc sec seeing focus_-100 was stopped early as I hit the upper alt limit. see /dis/focus* for spectra. TIP Tilt adjustments (seeing would blow up every once in a while, I tried to retake a sweep and get the best focus.)

I slewed to 179.6, which unwrapped the telescope correctly then came back at 180.2. This ate up 5+ minutes of time in just slewing.
