[evlatests] Receiver to look into ...

[Rick Perley]

    We took some sensitivity data (detailed results to be summarized at 
the meeting this morning), at X and C bands.  If we are looking into 
moisture problems this week, the following receivers should get priority 
treatment:

    A)  X-band:      Only antenna 25 has a sensitivity significantly 
worse than normal. 
                             Antennas 6, 18, 22 and 23 are about 30% 
below the median sensitivity of the others. 

    B) C-band:      EVLA antennas 17, 19, 24 and 26 have sensitivity far 
worse than normal. 
                            VLA antennas 6, 8, 10 and 15 are all 
significantly poorer than the other VLA antennas. 
                            EVLA antennas 2, 4, 5 and 23 are somewhat 
worse than nominal. 

    I haven't checked L-band, nor any of the higher frequency bands.  
(These latter are best done when skies are clear -- a rare sight these 
days ...)
