USNO Analysis Report for W19353 ($19DEC19XW) 
       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: PIETOWN did not record for the first 66 minutes of the session. 

Number of observations rejected during correlation:   56

    These were missed due to PIETOWN's missed scans.

Number of observations not usable by the software:     6
