USNO Analysis Report for W19070 ($19MAR11XW) 
       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: There were communications issues to PIETOWN and it did not observe. WETTZ13N missed 
the first six scans.

Number of observations rejected during correlation:   12

    The first six scans on each of the MK-VLBA:WETTZ13N and WETTZ13N:WETTZELL baselines.


Number of observations not usable by the software:     3 

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

Number of observations rejected during analysis:      15 

    The WETTZ13N:WETTZELL baseline was deselected, accounting for 14 scans.
