USNO Analysis Report for W19091 ($19APR01XW) 
       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: PIETOWN had trouble pointing, and no data was correlated.

Number of observations rejected during correlation:    0 

Number of observations not usable by the software:     2 

    observation  26, MK-VLBA :WETTZELL, NGC6251 , 08:58:27, quality codes - S:0, X:9 
    observation  27, MK-VLBA :WETTZELL, 1342+662, 09:01:06, quality codes - S:0, X:9 

Number of observations rejected during analysis:      24 

    The WETTZ13N:WETTZELL baseline was deselected, accounting for 21 observations.

    observation  24, MK-VLBA :WETTZELL, 1639+230, 08:55:16, had a G-code on S-band
    observation  45, MK-VLBA :WETTZELL, 1342+662, 09:28:19, which fits at -2595.8 +/- 79.6 ps
    observation  73, MK-VLBA :WETTZELL, 0716+714, 10:02:32, had a G-code on S-band
