IVS Analysis Report for I19101 ($19APR11XU) 
       This report is the official IVS analysis report that corresponds to 
       the database maintained by the IVS Data Centers for this session.  
   (Analyzed by Karen Baver, Goddard Space Flight Center VLBI Analysis Center.
    Spoolfile source: interactive solve/nuSolve analysis.) 

Problems: The KOKEE-SVETLOE and SVETLOE-WETTZELL baselines did not have enough good 
          observations to be usable.  Most observations that could have been included 
          had very large residuals.  The baselines were deselected.

Number of observations rejected during correlation:    0 

Number of observations not usable by the software:     5 

    observation    4, KOKEE   :WETTZELL, 1418+546, 18:33:36, quality code X-band: 0 S-band: 9 
    observation   17, KOKEE   :SVETLOE , NGC6251 , 18:57:19, quality code X-band: 9 S-band: 0 
    observation   18, KOKEE   :WETTZELL, NGC6251 , 18:57:19, quality code X-band: 0 S-band: 0 
    observation   29, KOKEE   :SVETLOE , 0415+398, 19:17:53, quality code X-band: 0 S-band: 9 
    observation   30, KOKEE   :WETTZELL, 0415+398, 19:17:53, quality code X-band: 0 S-band: 9 

Number of observations rejected during analysis:      18 

    The SVETLOE baselines were deselected due to having very few observations, which also had
    very high residuals.

Other comments: None.
