IVS Analysis Report for W19353 ($19DEC19XW) 
       This report is the official IVS analysis report that corresponds 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 PIETOWN's data were minused out from the start
          of the session through 08:19, probably due to an Xcube problem.

Number of observations rejected during correlation:   56 

    The first 28 MK-VLBA :PIETOWN and the first 28 PIETOWN :WETTZ13N observations were lost.
    (See above.)

Number of observations not usable by the software:     6
