USNO Analysis Report for I18172 ($18JUN21XU) 
       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: Many SVETLOE scans were deselected, resulting in only 5 scans on the KOKEE:SVETLOE baseline and 4 scans on the SVETLOE:WETTZELL baseline, not enough to get a good solution for each baseline. 

Number of observations rejected during correlation:    2
