              ------------- ACTIVITY LOG --------------
Observing Specialist:    R.McMillan
More pointing models tonight, as we assessed the feasibility of adjusting
the fiducial tables from on-sky measurements.  This still needs some
work, but is already improving the scatter of our pointing models, so the
results were implemented.
I also used spicam to check collimation, which looked fine and didn't
require any adjustment.  Then I closed up early in order to allow more
time for the pump to work on the echelle, which is impossible while the
telescope is moving.
