[evlatests] S8531, July 02 / 50% good.

[Vivek Dhawan]

2007 07 01, UT 11:03 to 13:34 (expected). As the Operator's log said:
the first hour of data was lost to computer problems.

Antennas 10 12 13 17 19 24 flagged out, but have fringes.
(Edo: load with FILLM CPARM 0,3,16,0 to ignore flags; then
use QUACK with about 20s cutout at the start of scans.)

The source sets  - last 10min the fringes are gone. The long
baselines show a phase wind of over 60 deg/min near the end. I
initially thought this might be an inadequate atmosphere model
for low elevation, but Barry thinks the model is unlikely to be
so much in error. So the cause is yet unknown.

Vivek.
