USNO Analysis Report for R1950 ($20JUN08XA) This report is a contributed analysis report that does not correspond to the database maintained by the IVS Data Centers for this session. (Analyzed by Nicole Geiger, Naval Observatory. Spoolfile source: interactive nuSolve analysis.) Problems: HART15M had a clock break at 06:16:21 (15.19 nsec). ISHIOKA missed scans from 13:00-17:00 UT due to elevation drive issues. MATERA started late, ~ 3 hours, due to antenna problems. NYALES20 observed with a warm receiver. NYALE13S was not included as there were communication issues between the antenna control unit and the subreflector, causing only 2.5 hours of observations; not included in the database. SEJONG had a data storage error and lost ~ 7 hours of data. YARRA12M had 4 clock breaks at 01:03:47 (-0.60 nsec), 02:14:27 (0.31 nsec), 12:17:50 (-0.64 nsec) and 13:25:21 (0.92 nsec). Parameterization comments: None. Other comments: None. ----------------------------------------- Session Statistics Observations: 6596 scheduled 4820 correlated (in database) 4309 recoverable (usable) 4253 used Session fit: 37.420 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used HART15M 1019 797 783 76.8% ISHIOKA 1648 1028 1012 61.4% KOKEE 1253 953 939 74.9% MATERA 1631 1158 1141 70.0% NYALE13S 1258 NOT CORR NOT CORR 0.0% NYALES20 1666 1250 1240 74.4% SEJONG 1430 824 818 57.2% WETTZ13N 1482 1148 1142 77.1% WETTZELL 1071 868 856 79.9% YARRA12M 734 592 575 78.3% --------------- --------- ----------- --------- ------ Station Total** 6596 4309 4253 64.5% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
