USNO Analysis Report for Q18015 ($18JAN15XK) 
       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: The correlator reports that NYALES20 "skipped 10 scans in sector 50-108 due to az encoder problems." WETTZELL reports "slightly lower fringe amplitude in [the] first four X-band channels." 

Number of observations rejected during correlation:   35 

Number of observations not usable by the software:     0 

Number of observations rejected during analysis:      28 
      WETTZ13N:WETTZELL was deselected as is the standard practice of this analysis center.


Other comments: None.
