USNO Analysis Report for I22117 ($22APR27XU) 
       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 Christopher Dieck, US Naval Observatory.
    Spoolfile source: interactive nuSolve analysis.) 

Problems: WETTZELL did not participate; out for cryo-cooler repair. 

Number of observations rejected during correlation:    0 

Number of observations not usable by the software:     3
