NASA Analysis Report for Q22079 ($22MAR20XK)
       This report is a contributed analysis report that does not correspond to
       the database maintained by the IVS Data Centers for this session.
   (Analyzed by Karen Baver, Goddard Space Flight Center VLBI Analysis Center.
    Spoolfile source: interactive solve/nuSolve analysis.)

Problems: The correlator report noted that, after 079-0814, the WETTZELL data recording times were shorter than the durations assumed in the schedule.  The report also noted that in this time frame, the file sizes were 50% or less than the assumed file sizes.

Number of observations rejected during correlation:    0

Number of observations not usable by the software:     4
