USNO Analysis Report for I20286 ($20OCT12XU) 
       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: With USNO's practice of deselecting G-codes, there were only 5 usable
scans and that is insufficient to get a result. No UT1 entry made. 

Number of observations rejected during correlation:    0 

Number of observations not usable by the software:    17
