[evlatests] Another check

[Rick Perley]

    One final check of system performance, prior to the 'flux 
densities'.  This was on the four planets (Venus, Mars, Uranus, Neptune 
-- which are all remarkably close to the sun at this time), to make sure 
we properly track them.   The weather was quite poor (rain, 20 -- 30 mph 
wind) at the time. 

    28 antennas were in the array (!), and fringed at all bands, except 
for ea15, which has no receiver at X and L bands.  (P-band excluded here). 

    There were only two antennas which did not provide good looking 
switched power.  For these two, the PDifs were zero-mean. 

    ea08 at Q-band
    ea02 at X-band.
