IVS Analysis Report for W19070 ($19MAR11XW) 
       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: None. 

Number of observations rejected during correlation:   12 
     
   The following observations were missed due to an operator error at WETTZ13N:

Number of observations not usable by the software:     3 

    observation   19, MK-VLBA :WETTZELL, NGC6251 , 09:07:04, quality code X-band: 9 S-band: 0 
    observation   22, MK-VLBA :WETTZELL, 1342+662, 09:14:11, quality code X-band: 9 S-band: 0 
    observation   66, MK-VLBA :WETTZELL, 1342+662, 10:10:19, quality code X-band: 9 S-band: 0 

Number of observations rejected during analysis:      15 

    observation   24, MK-VLBA :WETTZELL, 0955+476, 09:17:16, which fits at     -219.6 +/-      42.0 ps 

    Also the WETTZ13N:WETTZELL baseline was deselected, which deselected 14 observations.

Other comments: Due to a communications outage, the PIETOWN antenna could not be pointed, 
                and PIETOWN did not observe.

Parameterization: 
   8 parameters:
