IVS Analysis Report for V23086 (20230327-v23086)
       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: WETTZ13S(Ws) Y polarization has systematically low SNR, especially band A in Y pol.
                       Unable to use normal scripts to generate phase/polarization offsets. 
                       Used a template scan for phase offsets, and historical values for 
                       polarization offsets.

Number of observations rejected during correlation:    3
