USNO Analysis Report for I18071 ($18MAR12XU) 
       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: There are only 6 useable scans at the beginning of the session, an insufficient number to make a measurement, so this database will not be submitted or incorporated into our intensive series. KOKEE does not that some scans were recorded with station timing syncerr_le_3.

Number of observations rejected during correlation:    2 

Number of observations not usable by the software:    14
