[evlatests] AM889 on July 24

[Ed Fomalont]

AM889 on July 24:

1.4 GHz, 2 IFs, 2 Pols usual deep field correlator setup,
5 hour experiment, 3.3sec integration

antennas:
    11, 21, 25 out; 25 antennas working, 2 IFs, 2 Pols

Only strange problem:

 Large offsets on IF2, 8R-9R, 8R-17R correlators.

   Began suddenly between 15:12:12 and 15:12:15 and persisted to
end of run about 100 min later.   No other IF's affected.
