USNO Analysis Report for Q20069 ($20MAR09XK) 
       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: NYALES20 clock required a higher number of coefficients in its parameterization
than the other stations. Correlator reports that it had a high clock rate.

Number of observations rejected during correlation:    0 

Number of observations not usable by the software:     7
