MDM Trouble Report for 2001 Feb 21

Telescope: 1.3m
Observer(s): Lepine, Zurek (Columbia)
Instrument: Mk III spectrograph

Problem(s) Encountered:
We have tried to fix the focus problem on the spectrograph
reported yesterday. We measured line widths in a Ne arc for
different settings of the spectrograph focus and tilt values.
We found a satisfactory setting to be focus=3748 tilt=0, giving
a relatively uniform focus along dispersion. The instrument
previously was at focus=3918 tilt=25. We will experiment again 
next afternoon.
