USNO Analysis Report for R1875 ($19JAN02XA) 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 Megan Johnson, Naval Observatory. Spoolfile source: interactive nuSolve analysis.) Problems: KATH12M had DBBC drift throughout observations making ambiguity resolution very challenging. MATERA did not participate due to brake problems. NYALES20 missed 7 hours due to strong winds. YARRA12M had 2 clock breaks at ~02:00 and ~11:30. SEJONG required baseline clock offsets on most baselines. Parameterization comments: None. Other comments: None. ----------------------------------------- Session Statistics Observations: 7426 scheduled 4908 correlated (in database) 4713 recoverable (usable) 4596 used Session fit: 34.105 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used HART15M 1104 757 729 66.0% ISHIOKA 1718 1386 1362 79.3% KATH12M 987 653 617 62.5% KOKEE 1337 1066 1043 78.0% MATERA 1832 NOT CORR NOT CORR 0.0% NYALES20 1871 1073 1043 55.7% ONSALA60 1832 1288 1266 69.1% SEJONG 1338 1093 1072 80.1% WETTZ13N 1892 1336 1304 68.9% YARRA12M 941 774 756 80.3% --------------- --------- ----------- --------- ------ Station Total** 7426 4713 4596 61.9% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
