IVS Analysis Report for W19091 ($19APR01XW) 
       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:    0 

Number of observations not usable by the software:     4 

    observation   26, MK-VLBA :WETTZELL, NGC6251 , 08:58:28, quality code X-band: 9 S-band: 0 
    observation   27, MK-VLBA :WETTZELL, 1342+662, 09:01:06, quality code X-band: 9 S-band: 0 
    observation   34, WETTZ13N:WETTZELL, 0805+410, 09:07:50, quality code X-band: 8 S-band: 4 
    observation   68, WETTZ13N:WETTZELL, 0955+476, 09:59:00, quality code X-band: 9 S-band: 4 

Number of observations rejected during analysis:      20 

    observation   45, MK-VLBA :WETTZELL, 1342+662, 09:28:19, which fits at    -2574.0 +/-      70.7 ps 

    Also, the WETTZ113N:WETTTZELL baseline was deseiected, leading to the suppresion of
    19 observations.


Other comments: PIETOWN was unable to point its antenna due to communications being down.
