USNO Analysis Report for Q21263 ($21SEP20XK) 
       This report is a contributed analysis report that does not correspond to 
       the database maintained by the IVS Data Centers for this session.

This is a preliminary release that does not include ISHIOKA data.

Problems: ISHIOKA data have not been transferred yet, due to a
	  national Japanese holiday.
	  NYALES20 did not observe.

Number of observations rejected during correlation:    0
