IVS Analysis Report for Q20356 ($20DEC21XK) 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: None.

The correlator report provided the following station notes about issues: WETTZELL(V-Wz): The SR1U fringes in many scans were not detected due to RFI. Channels flagged for fringe fitting. SESHAN25(C-Sh): PCAL phase are unstable. Applied manual PCAL.
