IVS Analysis Report for I22089 ($22MAR30XU) 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: Many of the WETTZ13N-WETTZELL observations had large S-band sub-ambiguities (20 to 95 ns), but seven WETTZ13N-WETTZELL observations were included in an initial interactive solution. But a solution to determine EOP for the individual baselines failed due to a failure to invert the normal matrix. So a second solution that deselected the WETTZ13N-WETTZELL baseline was tried, and this soluiton succeeded. The WETTZ13N-WETTZELL baseline is not of great interest in this session, so it was deselected.
