[evlatests] Holography works!

[Rick Perley]

    The short holography test last night clearly shows the two arrays in 
perfect synchronism for holography. 

    Congratulations to all concerned for rooting out the bug. 

    Not everything is perfect, however.  Two items of note ...

    1) The EVLA antennas arrived at the source 5 minutes after the VLA.  
Longer than usual (but not as tardy as some other runs I've done).  Can 
anything be done to correct this? 

    2) All EVLA antennas went stone cold (i.e. stopped fringing) 
abruptly 23 seconds before the end.  I guess they had a different idea 
of when the run ended.  Not a big deal, but previous early terminations 
were always less than 10 seconds.  I hope this expansion is not the edge 
of a trend...
