IVS Analysis Report for W20037 ($20FEB06XW) 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 baseline seemed to have a sub-ambiguity, splitting the data into two parts. Number of observations rejected during correlation: 0 Number of observations not usable by the software: 47 observation 5, MK-VLBA :WETTZ13N, 1156+295, 07:17:11, quality code X-band: 0 S-band: 9
