Hi All,

    Not looking too good.  Is this the first test of 3.3 sec sampling?

AM889  Lband 2 if's 2 pols 7 channel:

14:00 - 1530  good phase stability, but fluctuating amp stability.

For calibrator at 16:04 until now.
LOST PHASE STABILITY ON ALL  TELESCOPES EXCEPT
   19 (ref)  13, 14, 16, 17, 18, 20, 21, 23, 24, 26, 27
                  i.e. only EVLA antennas

I FIND NO COHERENCE AMONG THE VLA ANTENNAS OR BETWEEN
THE VLA-EVLA ANTENNAS.

LOTS OF DATA OVERFLOWS

===================================================

Hard to see data from CV in much detail, but only EVLAxEVLA baselines are
useful after 1600.

Data on hamal.aoc.nrao.edu:  user 51 indisk 1, slot 4 (6 being still filled)
