                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky, R.McMillan (remote)
Nick and Dave got the telescope back together around 20:00 and our initial pointing check of Beta
Gem was a little off center on SPIcam, but not too bad for having the telescope taken apart.
SPIcam stest.0002 is an out of focus (+600 steps) image before collimation.
Tip/Tilts at NA2 (@21:40 MDT)
Start  -194, 1164
Change -44, -19
Final no change
Checked pointing between NA2 and BC1 (3x).  Looked good. Russet updated the ip_bc1.dat file.s
Checked pointing between NA2 and TR3 (3x).  Looked good, updated ip_tr3.dat file.
We managed to get a collimation check with the SH, Russet said it looked suprisingly good.
Adjusted collimation slightly
Comparison collimation spicam images are pointing_77_sigma_Leo.0021, before change, after change
image pointing_77_sigma_Leo.0022
I restarted the AgileICC for Anjum and she took several thousand Agile exposures.
I ran 3 focus sweeps with the SPIcam focus script and found no errors to report (PR777).
I finally took a pointing model around 02:30AM which took a little longer fro the 80 point model
due to clouds.  I had one bad data point, which took me a while to figure out which point it was
in the pterr file, but I eventually figured it out and removed it.  Implemented new pointing model
and emailed Mark, Nick, and the obs-specs the output files for their review.
By 04:30, when I finished taking and implementing the pointing model we were pretty well clouded in.
I gave up ato 05:00 due to clouds.
I believe I got the main high priority engineering tasks accomplished tonight.  The rest were low
priority and clouds interfered with those.
Slitty is not working, Fritz knows about this, so I was not able to check pointing at NA1.  The
other ports (other than NA2) were off a little and we adjusted appropriate their dat files.  All
other instruments checked out and appear to be working fine.
