IVS Analysis Report for W19164 ($19JUN13XW) 
       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: WETTZELL missed ~30 minutes due to a recorder error.
          WETTZELL rebooted its Mark5B+ at 07:27 and obtained its
          first fringe at 07:41.

Number of observations rejected during correlation:   20 

  Due to a WETTZELL recorder error described above, the following 
  pairs of MK-VLBA:WETTZELL and PIETOWN:WETTZELL observations were unsuccessful:
