IVS Analysis Report for Q20139 ($20MAY18XK) 
       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: The WETTZ13N:WETTZELL baseline was very noisy, and it was deselected.

Number of observations rejected during correlation:    0 

Number of observations not usable by the software:    17

    observation  222, ISHIOKA :SESHAN25, 0420+022, 07:34:13, which fits at     -279.7 +/-      72.1 ps 
    observation  223, ISHIOKA :WETTZ13N, 0420+022, 07:34:13, which fits at     -216.9 +/-      51.8 ps 
    observation  231, ISHIOKA :NYALES20, 0322+222, 07:35:44, which fits at    -3969.9 +/-      53.4 ps 
    observation  276, NYALES20:WETTZ13N, 0016+731, 07:40:52, which fits at      575.1 +/-      69.5 ps 

    Also 26 usable WETTZ13N:WETTZELL observations were deselected due to the noisiness of the baseline.

Other comments: 

  The correlator reported noted that NYALES20 observed with a warm receiver.
