[evlatests] ea28 pointing

[Ken Sowinski]

>From a pointing run done Friday night, November 1 IAT estimates
of tilt and az encoder offsets were made and incorporated in the
database.  The tilt error was over 2 arc-min, so the antenna would
not have worked well at K or Ka band.  Collimation errors must still
be determined for the high frequency bands and that will be attempted
tomorrow.

The pointing solution is poor and many trials were rejected for
having too large an estimated beamwidth.  Steve reported this
morning that there may still be some ACU problems.  If that is
so, a high quality pointing run awaits the resolution of that
problem.
