IVS Analysis Report for I21358 ($21DEC24XU)
       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: Nine observations had sub-ambiguities at approximately 12.5 ns and had to be removed from the solution.  The remaining observations provided a very noisy solution, and seven more observations were removed, leaving a solution with only 10 observations.  The resulting UT1 formal error was very large (119 microseconds).

Number of observations rejected during correlation:    0

Number of observations not usable by the software:     4
