IVS Analysis Report for W20058 ($20FEB27XW) 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 were divided into two sets by a sub-ambiguity. The smaller set was deselected. The WETTZ13N baselines were noisy. The UT1 formal error was large. Number of observations rejected during correlation: 0 Number of observations not usable by the software: 37 observation 3, PIETOWN :WETTZ13N, 1803+784, 07:15:20, quality code X-band: 0 S-band: 9
