IVS Analysis Report for I22255 ($22SEP12XU) 
       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 data showed multiple clock breaks and/or sub-ambiguities,
          especially in the second half of the session.  The data after
          the 18:57:48 observation were discarded, leaving 14 usable
          observations.  In addition, a clock break was set at
          18:47:30, in the middle of the usable observations. 
          The clock break was set at WETTZELL based on recent history.

Number of observations rejected during correlation:    0 

Number of observations not usable by the software:     4
