NASA Analysis Report for Q19216 ($19AUG04XK) 
       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: WETTZELL experienced a servo failure at the start of the session.  
          The correlator reported that the first six observations were off-source.

Number of observations rejected during correlation:    0 

Number of observations not usable by the software:     9 

  The following six observations were off-source due to the WETTZELL servo failure.
