IVS Analysis Report for R1976 ($20DEC07XA) 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: - Only one station, HART15M, used the correct chanel set up, one channel of X-band was removed. Numerous non-detections in both bands, more in X-band. - Due to data storage error SEJONG did not observe ~2.5hrs. - YARRA12M did not observe last ~1.25hrs due to insufficient space on disk. Parameterization comments: one clock break has been added to YARRA12M. Other comments: None. ----------------------------------------- Session Statistics Observations: 2440 scheduled 2323 correlated (in database) 1928 recoverable (usable) 1885 used Session fit: 37.081 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used HART15M 760 518 509 67.0% NYALE13S 759 593 579 76.3% ONSALA60 1026 865 854 83.2% SEJONG 774 553 542 70.0% WETTZELL 1034 958 930 89.9% YARRA12M 527 369 356 67.6% --------------- --------- ----------- --------- ------ Station Total** 2440 1928 1885 77.3% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
