[evlatests] Bad Phases

[Rick Perley]

    I forgot to include in the last description those antennas whose 
phases are particularly unstable from scan to scan.  The list is familiar:

    ea08, in AC
    ea10 in AC
    ea11 in BD
    ea18 in AC

    Antenna with notably bad amplitude stability include

    ea17 in AC
    ea19 in AC
    27 in all IFs
    26 in IF B
