IVS Analysis Report for W20051 ($20FEB20XW) 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 PIETOWN:WETTZ13N data was divided into two sets due to an apparent sub-ambiguity. The correlator reported that the MK-VLBA XR3U and XR4U channels were removed from fringe fitting. The UT1 formal error was very high. Number of observations rejected during correlation: 0 Number of observations not usable by the software: 56 observation 5, MK-VLBA :WETTZ13N, 3C274 , 07:17:25, quality code X-band: 0 S-band: 0
