NASA Analysis Report for AUM025 ($21FEB09XA) This report is a contributed analysis report that does not correspond to the database maintained by the IVS Data Centers for this session. (Analyzed by Sergei Bolotin, NVI, Inc. / NASA Goddard Space Flight Center. Spoolfile source: interactive solve/nuSolve analysis.) Correlator's comments: "Manual phase cal applied to all stations. Hb/Ke observed in mixed-mode configuration VGOS-Legacy baselines processed with -PRR+LR option in fourfit. Legacy-Legacy baseline processed with -PRR option. VGOS-VGOS baselines have been processed with -PI." Problems: - KATH12M "correlated with very high residual delay, which leads to very high residual rate. A lot of clock breaks." Clocks of the station are very unstable, their contstraints were increased to 216 ps/hr. Parameterization comments: six clock breaks were added to KATH12M. Other comments: None. ----------------------------------------- Session Statistics Observations: 2184 scheduled 2098 correlated (in database) 2046 recoverable (usable) 1833 used Session fit: 36.480 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used HOBART12 930 874 805 86.6% KATH12M 1228 1148 959 78.1% WARK12M 1160 1099 1013 87.3% YARRA12M 1050 971 889 84.7% --------------- --------- ----------- --------- ------ Station Total** 2184 2046 1833 83.9% * 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.
