IVS Analysis Report for Q21179 ($21JUN28XK) 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 correlator reported that the NYALES20 GPS-fmout values were out of range and that the NYALES20 clock had an enormous rate. This seemed to contribute to some large residuals in the NYALES20 observations and a large session fit (73.385 ps) in the analysis solution. Because of NYALES20's large clock rate, the reference clock was changed from NYALES20, the default chosen by the nuSolve software, to WETTZ13N. RFI in S-band affected SESHAN25, WETTZ13N, and WETTZELL.

Maser behaviour needs to be investigated. Nevertheless, gps-fmout values had to be used for correlation including an enormous clock rate. SESHAN25 (Sh/C): RFI in S-band particularly affecting channel SR5U; channel removed from fringe fitting. Some non-detections in both bands. WETTZ13N (Wn/W): RFI in S-band on baseline Wn-Wz. WETTZELL (Wz/V): RFI in S-band on baseline Wn-Wz.
