USNO Analysis Report for Q20139 ($20MAY18XK) 
       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: The WETTZ13N:WETTZELL baseline could not be wrangled into submission,
so it was deselected.

Number of observations rejected during correlation:    0 

Number of observations not usable by the software:     2 

    observation  78, SESHAN25:WETTZ13N, 1849+670, 07:09:56, quality codes - S:0, X:9 
    observation 298, SESHAN25:WETTZ13N, 1849+670, 07:43:39, quality codes - S:0, X:9 

Number of observations rejected during analysis:      45 

    Deselected the WETTZ13N:WETTZELL baseline, accounting for 41 observations.

    observation  81, ISHIOKA :NYALES20, 3C371   , 07:11:00, which fits at  -148.1 +/- 35.9 ps 
    observation  82, ISHIOKA :SESHAN25, 3C371   , 07:11:00, which fits at  -153.6 +/- 35.5 ps 
    observation 231, ISHIOKA :NYALES20, 0322+222, 07:35:44, which fits at -3900.3 +/- 37.9 ps 
    observation 276, NYALES20:WETTZ13N, 0016+731, 07:40:52, which fits at   620.6 +/- 36.0 ps 

Other comments: None.
