     Reminder:

     VLA Tests Results Meeting, Rm 317, 10AM -- noon (max), Thursday, 12 
June.

     We have three probable presentations so far:

     1) Results from elevation gain tests of June 09.   (Rick)

          A 6-hour tracking of 3C286 from zenith to el = 10 degrees 
reveals which antennas have seriously misaligned optics, and/or bad gain 
stability and/or bad switched power calibration.

     2) Some early results from long-term 'stress test' monitoring. 
(Emmanuel/Rick)

         The 'stress test' has been running for about 18 months now, and 
we are getting interesting (and useful) results from the derived antenna 
gains, following application of the switched power.  An analysis of 
Ku-band results will be shown.

     3) Some early results from the new 'Moon' test program. (Keith).

         The moon makes a useful 'hot load' for monitoring and measuring 
various instrumental characteristics, notably the still unsolved 'PDif' 
compression issue.  A standard script has been generated by Ken, to 
permit near-effortless monitoring.

     There is time for more -- let me know if you have something to present.
