IVS Analysis Report for AUA087 ($22APR20XA) This report is the official IVS analysis report that corresponds 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.) Problems: HOBART12 Late start (1830UT). Numerous DBBC issues early, incorrect mode set on DBBC3 - fixed by 0215UT. No usable data during the first 3hrs, practically no good observations for the first 8 hrs. YARRA12M No usable observations during the first 3hrs. KATH12M Late start (~3hrs), practically no good observations for the first 8 hrs. Similar DBBC issues to Hb, same fix was identified at 0220UT. Multiple subambiguities in X-band. Parameterization comments: A clock break was added to KATH12M. Other comments: None. ----------------------------------------- Session statistics Observations: 5641 scheduled 5109 correlated (in database) 4146 recoverable (usable) 3866 used Session fit: 38.654 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used HART15M 1671 1295 1264 75.6% HOBART12 2499 1770 1608 64.3% KATH12M 2520 1775 1516 60.2% WARK12M 2096 1584 1538 73.4% YARRA12M 2496 1868 1806 72.4% --------------- --------- ----------- --------- ------ Station Total** 5641 4146 3866 68.5% * 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.
