NASA Analysis Report for R4986 ($21FEB18XE) 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 Sergei Bolotin, NVI, Inc. / NASA Goddard Space Flight Center. Spoolfile source: interactive solve/nuSolve analysis.) Problems: - AGGO, FORTLEZA and NYALES20 did not participate. - YARRA12M missed 5.5hrs of the session. - WARK12M has bimodal residuals in X-band, many observations were deselected. - Strange residuals of 1342+662 in S-band for MEDICINA:WETTZ13N and NYALE13S:WETTZELL baselines, look like a sinusoid with an amplitude 1000-2000ns and a period of a day. The group delays do not show such effect, though many of observations of the source at these baselines are outliers. Estimation of source coordinates does not improve a solution. Parameterization comments: two clock breaks were added to YARRA12M. Other comments: None. ----------------------------------------- Session Statistics Observations: 2912 scheduled 2619 correlated (in database) 2170 recoverable (usable) 1871 used Session fit: 25.826 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used AGGO 171 MISSED MISSED 0.0% HART15M 670 401 388 57.9% KOKEE 591 449 396 67.0% MEDICINA 891 830 770 86.4% NYALE13S 593 467 459 77.4% WARK12M 446 300 190 42.6% WETTZ13N 936 757 611 65.3% WETTZELL 934 783 640 68.5% YARRA12M 592 353 288 48.6% --------------- --------- ----------- --------- ------ Station Total** 2912 2170 1871 64.3% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
