              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
While waiting out weather, I ran an altitude tests for the PMSS. Details
in separate email.
Checked DIS focus in dome.
Once we opened to partly cloudy skies, we checked echelle pointing and
found it within 10".
Made DIS spectrograph/slitviewer focus comparisons.
Investigated pattern noise seen in NICFPS checkout images.
Collimation with Shack Hartmann.
Ran high altitude pointing model and implemented.
