IVS Analysis Report for R4974 ($20NOV26XE) This report is the official IVS analysis report that corresponds to the database maintained by the IVS Data Centers for this session. (Analyzed by Christopher Dieck, US Naval Observatory. Spoolfile source: interactive nuSolve analysis.) Problems: FORTLEZA - Did not participate. URUMQI - Did not participate. Parameterization comments: - Baseline clock offsets were applied on the following baselines: MEDICINA:YEBES40M Other comments: - Due to dropped channels, the S-band ambiguity spacing is 50 ns on all YEBES40M baselines. - The five stations involved in the session are within a ~31 degree longitude range. This geometry is not conducive to achieving the typical formal errors in EOPs, explaining the elevated formal errors of this session. - The originally released database has been declared the final release. This analysis report reflects that final release. ----------------------------------------- Session Statistics Observations: 3296 scheduled 1982 correlated (in database) 1804 recoverable (usable) 1692 used Session fit: 21.408 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used FORTLEZA 484 MISSED MISSED 0.0% HART15M 659 386 386 58.6% MEDICINA 1157 858 845 73.0% URUMQI 876 MISSED MISSED 0.0% WETTZ13N 1160 780 682 58.8% WETTZELL 1126 770 673 59.8% YEBES40M 1130 814 798 70.6% --------------- --------- ----------- --------- ------ Station Total** 3296 1804 1692 51.3% * Recoverable: can be included in the solution. ** Total includes distinct observations only.

MISSED: Baseline was scheduled, but at least one of the sites did not observe. NOT CORR: Baseline was scheduled but not correlated. NO DATA: The baseline's stations were both correlated, but they did not observe together. DESELECTED: Usable data was generated for the baseline, but the analyst rejected it.
