IVS Analysis Report for R1928 ($20JAN07XA) 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, NASA Goddard Space Flight Center. Spoolfile source: interactive solve/nuSolve analysis.) Problems: SEJONG is noisy. They changed some setting for a polarization and LNA test in December and apparently this affected the last few R1 sessions. Some refringing was done to correct X-band subambiguities and ~50% more observations are used on the SEJONG baselines. NYALES20 gets only ~6 hours of usable observations. They missed the first ~15.5 hours due to very high winds, and then had to go down after a few hours to recool for ~2.2 hours. YARRA12M has small clock breaks at ~01:20 and ~11:05 UTC. Parameterization comments: None. Other comments: NYALE13S observed for ~1 hour, but the data is not usable. ----------------------------------------- Session Statistics Observations: 6098 scheduled 3461 correlated (in database) 2612 recoverable (usable) 2532 used Session fit: 35.276 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used HART15M 1188 769 762 64.1% MATERA 1911 1143 1137 59.5% NYALE13S 1707 8 NOT USED 0.0% NYALES20 1887 386 358 19.0% ONSALA60 1975 1184 1137 57.6% SEJONG 986 199 157 15.9% WETTZ13N 2038 1285 1269 62.3% YARRA12M 504 250 244 48.4% --------------- --------- ----------- --------- ------ Station Total** 6098 2612 2532 41.5% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
