[evla-sw-discuss] [Vlite-external] Lost correlations on V0 =EA14

[Bill Sahr]

Well, this alert is getting into the dbase.  I did a direct
search of the alertdata table in evlampts on lando, the
production dbase for evla antenna monitor data.

I searched for any match to "L305" & "SYNC_DETECT".

The select statement was:
  select * from alertdata where devicename='L305' and
monpointname='SYNC_DETECT' order by timestamp;

11,353 results were obtained with timestamps ranging from
56406.6775386 (4/23/2013, 16:59:35) to 57055.8308487
(2/2/2015, 19:56:25).
