USNO Analysis Report for Q20363 ($20DEC28XK) 
       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 Nicole Geiger, US Naval Observatory.
    Spoolfile source: interactive nuSolve analysis.) 

Problems: WETTZ13N did participate due to a critical servo failure
                   in elevation axis. 

Number of observations rejected during correlation:    0 

Number of observations not usable by the software:     0 

Number of observations rejected during analysis:       1
