IVS Analysis Report for R1863 ($18OCT08XA) 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: There are two large clock breaks at WETTZELL, at ~01:40 (-.3737764 seconds) and at ~11:59 (+.3737764 seconds). A nuSolve solution with clock breaks at those times aborts in the Solve solutions for baseline weights and EOP's. Therefore, the clock breaks are not used and the ~10 hours of data in between were deselected. WETTZ13N was used as the clock reference instead of WETTZELL. Two clock breaks are used at YARRA12M, at 12:04 and 13:58. The breaks look like maser cycle slips. Parameterization comments: None. Other comments: None. ----------------------------------------- Session Statistics Observations: 8994 scheduled 8704 correlated (in database) 8132 recoverable (usable) 7221 used Session fit: 26.810 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used FORTLEZA 850 783 701 82.5% HART15M 1313 1211 1124 85.6% ISHIOKA 1727 1612 1533 88.8% KATH12M 1079 988 928 86.0% MATERA 2117 1581 1485 70.1% MEDICINA 2176 2044 1917 88.1% NYALES20 1962 1790 1695 86.4% ONSALA60 2091 1961 1840 88.0% WETTZ13N 2072 1941 1714 82.7% WETTZELL 1558 1452 664 42.6% YARRA12M 1043 901 841 80.6% --------------- --------- ----------- --------- ------ Station Total** 8994 8132 7221 80.3% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
