[evlatests] Tardy Antennas

[Rick Perley]

     We ran a test last night which required some long slews.  It turned 
out that some were long in azimuth but not in elevation, and vice 
versa.  Looking at the data, it's clear that:

     1) antennas 3, 5, 12, 14 and 21 are slower in azimuth slews than 
the others.  Antennas 14 and 21 are the worst -- fully 20 seconds behind 
the fastest ones for changes in azimuth of about 120 degrees (3 minute 
slew).

     2) All antennas are very close in elevation slew speed.
