Analysis Report for R1645 ($14JUL21XA) (Analyzed by David Gordon, GSFC Analysis Center. Spoolfile source: interactive solve/nuSolve analysis.) Problems: Westford is problematic. The S-band was fringed with only 2 channels (S2 and S3) from the start until 04:00. The ambiguity spacings change from 50 to 100 nsec at 04:00, except for TS-WF where there is only 1 channel before 04:00. It is possible to resolve ambiguities so we have elected to keep the data before 04:00, except on the TS-WF baseline. A clock break is set at 04:00 at Westford, but it is very small (-.04 +/- .03 nsec). The baseline clocks are fairly large on the WF baselines, ~140-370 psec. The Westford baselines are noisy, in the 100-200 psec range. Seshan started late and no fringes were found. Parameterization comments: None. Other comments: None. ----------------------------------------- Session Statistics Observations: 6790 scheduled 4857 correlated (in database) 4687 recoverable (usable) 4471 used Session fit: 40.843 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used FORTLEZA 756 582 560 74.1% HART15M 1060 834 816 77.0% HOBART12 995 810 794 79.8% KATH12M 1145 921 905 79.0% KOKEE 1391 1127 1089 78.3% NYALES20 1577 1271 1244 78.9% SESHAN25 1787 NOT CORR NOT CORR 0.0% TSUKUB32 1945 1478 1342 69.0% WESTFORD 1391 1099 981 70.5% WETTZELL 1533 1252 1211 79.0% --------------- --------- ----------- --------- ------ Station Total** 6790 4687 4471 65.8% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
