IVS Analysis Report for W19028 ($19JAN28XW) 
       This report is the official IVS analysis report that corresponds to 
       the database maintained by the IVS Data Centers for this session.  
   (Analyzed by Sergei Bolotin, NVI, Inc. / NASA Goddard Space Flight Center.
    Spoolfile source: interactive solve/nuSolve analysis.) 

Problems: WETTZELL and WETTZ13N did not observe. No log files from MK-VLBA and PIETOWN.

Number of observations rejected during correlation:    0 

Number of observations not usable by the software:     0 

Number of observations rejected during analysis:       2 

    observation   13, MK-VLBA :PIETOWN , 1418+546, 08:57:46, which fits at      329.0 +/-      35.1 ps 
    observation   50, MK-VLBA :PIETOWN , 1520+437, 10:28:11, which fits at      423.4 +/-      39.0 ps 

Other comments: Preliminary solution; the data for WETTZ13N and WETTZELL have not arrived yet.
