USNO Analysis Report for Q18260 ($18SEP17XK) 
       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: NYALES20 did not participate due to icing on the antenna. 

Number of observations rejected during correlation:    0 

Number of observations not usable by the software:     3

    observation 10, ISHIOKA:WETTZ13N, 1441+252, 07:05:15, quality codes - S:9, X:0
    observation 41, ISHIOKA:WETTZELL, 2000+472, 07:24:25, quality codes - S:0, X:9
    observation 42, ISHIOKA:WETTZ13N, 2000+472, 07:24:25, quality codes - S:0, X:9

Number of observations rejected during analysis:      34 

    The 32 scans of the WETTZELL:WETTZ13N baseline were deselected. They were 
    not useful for analysis.

    observation 73, ISHIOKA:WETTZ13N, 0749+540, 07:46:20, which fits at 327.43 +/- 74.05 ps
    observation 74, ISHIOKA:WETTZELL, 0749+540, 07:46:20, which fits at 238.81 +/- 71.22 ps
