IVS Analysis Report for Q23177 (20230626-q23177) 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: nuSolve solutions.) Problems: Ns Low pcal amplitudes in X-band Ny Low pcal amplitudes in X-band Ny Almost no detections in X-band, some non-detections in S-band as well Sh No fringes in last four X-band channels Sh Removed channel from fringe fitting: X13LR, X10UR, X12UR, X11UR, X13UR Wz Did not participate due to receiver problems Wz Minused out No usable NYALES20/SESHAN25 data were found during analysis. The usual parameterization, which includes NYAL13S station coordinates, produces a solution with an enormous UT1 formal error, 403775.21 microsec, presumably due to the data loss. Turning these parameters off gives a much more reasonable value of ~ 39 microseconds, but this would still be too large to be usable in the EOP products.
