IVS Analysis Report for W19094 ($19APR04XW) 
       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: MK-VLBA's RDBE-1 timing was not synced from 07:15 until 08:45, after the system was rebooted.
          MK-VLBA observations made during that time failed.

Number of observations rejected during correlation:   78 

    39 MK-VLBA:PIETOWN and 39 MK-VLBA:WETTZELL observations were not recorded during the session
    due to the MK-VLBA RDBE-1 problem noted above.

Number of observations not usable by the software:     2 

    observation   19, PIETOWN :WETTZELL, 1606+106, 07:56:17, quality code X-band: 0 S-band: 0 
    observation   47, MK-VLBA :WETTZELL, 1342+662, 08:48:44, quality code X-band: 9 S-band: 0 

Number of observations rejected during analysis:       4 

    observation   27, PIETOWN :WETTZELL, 0714+457, 08:16:02, which fits at      570.3 +/-      43.4 ps 
    observation   39, PIETOWN :WETTZELL, 1300+580, 08:41:20, which fits at     -187.3 +/-      57.6 ps 
    observation   70, MK-VLBA :PIETOWN , 1725+123, 09:06:59, which fits at      302.9 +/-      77.2 ps 
    observation   71, MK-VLBA :WETTZELL, 1725+123, 09:06:59, which fits at      391.8 +/-      83.4 ps 

Other comments: WETTZ13N did not observe due to maintenance.
                The PIETOWN SR2U channel was removed from fringe fitting.
