USNO Analysis Report for Q20053 ($20FEB22XK) 
       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: Fringes were again not found on channles XR3U and XR4U. There is a high
formal error, perhaps resulting from these lost channels.

Number of observations rejected during correlation:    0 

Number of observations not usable by the software:     2 

    observation   2, WETTZELL:MK-VLBA , 3C274   , 07:32:08, quality codes - S:0, X:9
