USNO Analysis Report for I22061 ($22MAR02XU) 
       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: Several non-detections, and only 18 observations were used. The formal error was elevated as well. 

Number of observations rejected during correlation:    0 

Number of observations not usable by the software:    17
