[evlatests] Multiple Configurations ...

[Rick Perley]

     The explanation for the multiple 'configurations' is clear, but 
another question is raised ...

     There were 5 antennas moved yesterday.  It's clear that each time 
an antenna was taken out, another 'configuration' was made.  At P-band, 
five different configurations resulted.

     However, the antenna files for each of the five are identical -- 
the fact that antennas were taken out of service for a while, then 
reappeared later in a different place, didn't reach the Executor. 
Indeed, the first of the five P-band files contains the data taken at 
the beginning of the run (with all 27 antennas in the original 
positions), and the data at the end of the run, when five of them were 
in new positions.  The other four databases all correspond to short 
periods of time during which the actual number of antennas available was 
less than 27.  Yet all five databases have the same AN file.

     There's no harm in this, as the new antennas provided no fringes 
after having been replanted.
