Self-cross correlations should be in Rick's data for every other
antenna.

I was thinking of getting with Paul (who knows how to process this
with pulsar code) today to record the 20Hz signal for one or more
antennas while we change azimuth manually; and elevation.

And speaking of phase changes with antenna direction, I'm struggling
to think about this: the so-called 'baseline fits' do not discriminate
by R,L. Currently, no parallactic-angle correction is done to the data
(e.g. AIPS CLCOR PANG) before fitting the positions, does that have
any bearing on the current problem?
