IVS Analysis Report for R1876 ($19JAN07XA) 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: KATH12M: Very serious problems with drifting DBBC. The single band delays are unstable and have several large breaks and cannot be used to resolve the group delay ambiguities. The group delays are spread over sevaral dozen ambiguities and are not easily resolved. Nearly half of the KATH12M data is not used and the usable data is much noisier than usual. YARRA12M clock breaks at ~00:38 and ~11:36 UTC. Parameterization comments: None. Other comments: None. ----------------------------------------- Session Statistics Observations: 4278 scheduled 4025 correlated (in database) 3224 recoverable (usable) 3151 used Session fit: 47.775 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used HART15M 1199 973 953 79.5% KATH12M 1233 687 652 52.9% KOKEE 927 706 692 74.6% MATERA 1396 1096 1077 77.1% SEJONG 1169 839 818 70.0% WETTZ13N 1438 1135 1119 77.8% YARRA12M 1194 1012 991 83.0% --------------- --------- ----------- --------- ------ Station Total** 4278 3224 3151 73.7% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
