IVS Analysis Report for Q20174 ($20JUN22XK) 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.) Updated to add the correlator report's station notes. Problems: None.

SESHAN25 (Sh/C): Ok. WETTZ13N (Wn/W): RFI in S-band channel SR1U on baseline Wn-Wz; channel removed from fringe fitting on this baseline. WETTZELL (Wz/V): RFI in S-band channel SR1U on baseline Wn-Wz; channel removed from fringe fitting on this baseline.
