USNO Analysis Report for I19101 ($19APR11XU) 
       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 SVETLOE baselines were very noisy and negatively impacted the solution, 
          so were deselected.

Number of observations rejected during correlation:    0 

Number of observations not usable by the software:     3 

    observation   4, KOKEE   :WETTZELL, 1418+546, 18:33:36, quality codes - S:9, X:0 
    observation  18, KOKEE   :WETTZELL, NGC6251 , 18:57:19, quality codes - S:0, X:0 
    observation  30, KOKEE   :WETTZELL, 0415+398, 19:17:53, quality codes - S:9, X:0 

Number of observations rejected during analysis:      20

    The baselines of SVETLOE were deselected, accounting for 20 observations.

Other comments: None.
