[evlatests] ea03 at C-band

[Rick Perley]

    The sensitivity issue with ea03 has been resolved.  (I leave it to 
Gordon to describe what he found...)

    A short observation this morning shows that ea03 has a sensitivity 
near the expected range. 

    However, I'll point out that the two wide-band C-band antennas (3 
and 4) have sensitivities notably (but not greatly) poorer than the 
other (old OMT) EVLA antennas at this band.   Their Tsys/effic is near 
60K at 4885 MHz. 

    A careful sweep of the full bandpass will be done shortly.
