IVS Analysis Report for R1823 ($18JAN02XA) 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.) Problems: KOKEE's clock was very unstable, with at least 5 breaks. Three of these are used, at 20:56, 23:11, and 08:18. Two other breaks, at ~17:38 and ~22:07, result in intervals too short for the Solve global solution, so many points had to be deselected. YARRA12M has two small clock breaks, at ~00:53 and ~12:23. HART15M's clock is noisy. The clock constraint was raised to 10.E-14. Parameterization comments: None. Other comments: None. ----------------------------------------- Session Statistics Observations: 3652 scheduled 3357 correlated (in database) 3109 recoverable (usable) 2989 used Session fit: 37.426 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used FORTLEZA 552 456 442 80.1% HART15M 916 746 738 80.6% ISHIOKA 739 683 660 89.3% KATH12M 1004 909 865 86.2% KOKEE 836 730 659 78.8% NYALES20 1145 843 817 71.4% WETTZ13N 1256 1076 1047 83.4% YARRA12M 856 775 750 87.6% --------------- --------- ----------- --------- ------ Station Total** 3652 3109 2989 81.8% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
