IVS Analysis Report for R1856 ($18AUG20XA) 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: No fringes to NYALES20. They had some technical problems which resulted in no fringes for several sessions around this time. Antenna failure at WARK12M, no data last ~6 hrs. Parameterization comments: None. Other comments: The WETTZ13N-WETTZELL baseline was deselected, just noise. FORTLEZA observed with a warm receiver. ONSALA60 was tagged along, so it does not get many observations 3C48 must be adjusted in the solution, it shows an ~58 mas offset from the apriori. ----------------------------------------- Session Statistics Observations: 6908 scheduled 5206 correlated (in database) 4973 recoverable (usable) 4510 used Session fit: 29.604 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used FORTLEZA 1238 989 972 78.5% HART15M 1183 1023 1001 84.6% KATH12M 1365 1136 1075 78.8% MEDICINA 1497 1244 1199 80.1% NYALES20 1367 NOT CORR NOT CORR 0.0% ONSALA60 687 557 546 79.5% SESHAN25 1390 1078 942 67.8% WARK12M 960 556 523 54.5% WETTZ13N 1419 1172 900 63.4% WETTZELL 1408 1154 880 62.5% YARRA12M 1302 1037 982 75.4% --------------- --------- ----------- --------- ------ Station Total** 6908 4973 4510 65.3% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
