[evlatests] Something Wrong with ea01

[Rick Perley]

    I ran a holography file (using the VLA correlator) last night, for 
C, X, and K bands.  (This, to determine the beam polarizations). 

    Antenna 1 had to be removed at all three bands.  The problems with 
it are the same at all 3 bands:

    Large changes in both amplitude and phase -- the latter are 
typically 100 degrees at X-band.  The changes occur between scans -- 
never within one.  The effects are the same in all IFs.
