[evlatests] AJ337 evaluation

[Walter Brisken]

AJ337 does not need to be reobserved.

Details:

2.5 hours X-band continuum.

No antenna 11 or 25.  All 26 other antennas look pretty good except for
va09: all IFs is intermittantly flagged with duty cycle of 1/3 for 1 
hour of the observation.

1331+305 is first scan of project and it is ok once on source.

2 of 12 phase calibrator scans are over-flagged on most VLA antennas. 
Phases are stabke enough that this should not hurt the observation and it 
appears self cal should work on the target source.  Unflagged data look 
OK.

The second half one calibrator scan showed excessively large amplitudes, 
normal phases.  Needs to be flagged.

Phases are stable on all IFs

NO problems with any of the EVLA antennas.

Estimated loss of data from failures :           0%
Estimated amount of underflagging :              0.3% by antenna*time
Estimated amount of target source overflagging : 0.5% by antenna*time
Estimated amount of calib source overflagging :  11% by antenna*scan
