USNO Analysis Report for Q21261 ($21SEP18XK) 
       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 Nicole Geiger, US Naval Observatory.
    Spoolfile source: interactive nuSolve analysis.) 

This is a resubmission with corrected UT1 formal error statistics.

Problems: ISHIOKA did not participate due to antenna EL motor trouble. 

Number of observations rejected during correlation:    0 

Number of observations not usable by the software:     1
