[evlatests] Tests April 13

[Barry Clark]

Forgot one item:  I played around with a different amplitude compensation
to see how it affects closure.  Done at X band using all four EVLA 
antennas.  I'd appreciate it if somebody could have a look and see if
it makes a difference.  I used the alternate compensation from
20:48 to 20:56 TAI.  There was standard compensation flanking, from
20:41 to 20:48 and 20:56 to 21:03.
