NASA Analysis Report for Q20179 ($20JUN27XK) 
       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.) 

Updated to add an entry in the problems section.
Corrected to change the session in the e-mail title.

Problems: The first nine observations failed.  The correlator reported that this
          was due to an unspecified scheduling error that affected MK-VLBA.

Number of observations rejected during correlation:    9
