IVS Analysis Report for AOV024 ($18JUN19XA) This report is the official IVS analysis report that corresponds to the database maintained by the IVS Data Centers for this session. (Analyzed by David Gordon, Goddard Space Flight Center. Spoolfile source: interactive solve/nuSolve analysis.) Preliminary version without SYOWA data. SYOWA data will arrive by icebreaker after April 2019. Problems: KASHIM11 is deselected. The ambiguities are too small to resolve reliably (3.3 nsec in X-band and 12.5 nsec in S-band). Parameterization comments: None. Other comments: The version 1 databases were regenerated at GSFC to remove some access codes that interfere with the Calc/Solve/nuSolve analysis. The new version 1 databases were submitted to IVS. Source name 1600+43B was changed to 1600+43A. Earlier observations gave the same position for both source names. 1600+43B was changed to 1600+43A in all earlier databases for ICRF3. The name 1600+43B should not be used anymore. ----------------------------------------- Session Statistics Observations: 2704 scheduled 1755 correlated (in database) 1688 recoverable (usable) 1318 used Session fit: 77.096 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used HOBART26 869 685 564 64.9% KASHIM11 676 318 NOT USED 0.0% KATH12M 911 757 610 67.0% SEJONG 747 457 430 57.6% SYOWA 637 NOT CORR NOT CORR 0.0% WARK12M 712 471 456 64.0% YARRA12M 856 688 576 67.3% --------------- --------- ----------- --------- ------ Station Total** 2704 1688 1318 48.7% * Recoverable: can be included in the solution. ** Total includes distinct observations only.

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.
