[evlatests] Global Troubles

[Rick Perley]

    The entire array is not in good shape this morning.  From 'stress 
test' data taken last night, I find:

    1)  Antennas 13, 21 and 25 are low in sensitivity at all bands, by 
factors of 2 to 7.  They also provide very large closure errors amongst 
themselves.

    2) Even after removing these three antennas, large closure errors 
remain on nearly all antennas (VLA and EVLA)-- but not as large as those 
associated with 13, 21 and 25. 

    3) Many antennas are 'pulsing' -- there are regular short-duration 
drops in their amplitudes, of period 10 or so seconds. 

    It would seem likely these are all connected to the hardware work 
done yesterday?
