[evlatests] latest stress

[Rick Perley]

    Ken's automated stress-tester is now working in final form.  It was 
run a few minutes ago, with the following results:
   
    *  All antennas, all bands working as well as I've ever seen.

    *  Antenna 16 is now working properly on all four IFs. 

    *  VLA antenna 8, at Q-band, is still not fringing, and the data are 
not flagged. 

    *  There are significant sensitivity issues at two bands:

          o  At L-band, antenna 13 is poor in all four IFs.  Antenna 21 
is poor in IFs A and B. 

          o  At K-band, antenna 19 is poor in all four IFs.  Antennas 24 
and 25 are marginal in all four IFs. 

          *** 'Poor' means sensitivity down by a factor of 2 or more.  
Marginal means down by 1.5 or so.  ***

    In all, the data taking, and the quick quality review, took no more 
than 30 minutes.
