[evlatests] Baselines data, X-band, April 18.

[Vivek Dhawan]

Nine EVLA antennas were included in the run, 01:02-05:50 UT. All nine 
worked OK on all 4 IFs for 4 hours. The baselines and phase stability
I will report on later, mostly things looked pretty good.

At 04:10 or so, there was an 'event', unrecorded in the log, after which
every EVLA antenna continued to produce fringes, but had one or more of
the following ills (VLA antennas were unaffected):

A phase jump on one or both IF pairs at 04:10.

Low amplitudes (on one pair of IFs) from 04:10 on.

Multiple phase states from 04:10 on - jumping back and forth rapidly.

Mostly, the 2 IF pairs did different things on a given antenna. I
suspect (naturally) the L302's. What L302 error messages should I look
for in the log? Any other ideas?

Was the pointing data (just after this time) good? Does anyone have data 
after this time to say if the problem persists?

Vivek.

(P.S. the L352 RTP data have no hint of any of the problems above)
