[evlatests] What setup problems???

[Rick Perley]

    I generated a script to test OSRO mode observations by changing 
bands every couple of minutes.  The observations were of three very 
strong objects (3C286, 2007+4029, Cygnus A), in OSRO mode 1 (two 
subbands, full polarization), in four bands:  L, S, C, and X.   Note 
that changing into and out of X-band requires a 'configuration 
change'.   Band changes were made every 2.5 minutes. 

    Results:

    Superb Data!!!  Every antenna that was supposed to fringe did so, 
with the only occasional exceptions being clearly due to a 'failure to 
tune' -- I'll provide a separate list later on which ones didn't do what 
they were told to do. 
    Each change of band was accompanied by about (and only!) 10 to 15 
seconds of flagged (or bad) data -- exactly as expected for a 
subreflector or source change.  There was *NO* additional loss of data 
found when switching to, or from X-band. 

    FITLD reported only 0.49% of the data being pure zero.

    All looks very nice indeed from this simple, but fairly demanding, 
test.
