IVS Analysis Report for Q20244 ($20AUG31XK) This report is the official IVS analysis report that corresponds to the database maintained by the IVS Data Centers for this session. (Analyzed by Karen Baver, Goddard Space Flight Center VLBI Analysis Center. Spoolfile source: interactive solve/nuSolve analysis.) Problems: This session was reprocessed to turn off bad WETTZELL cable values. This slightly improved the UT1 formal error and the session fit, and this allowed the inclusion of five more observations. Number of observations rejected during correlation: 0 Number of observations not usable by the software: 9 observation 19, SESHAN25:WETTZ13N, 1806+456, 07:08:38, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 20, SESHAN25:WETTZELL, 1806+456, 07:08:38, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 45, WETTZ13N:WETTZELL, 0814+425, 07:23:08, quality code X: 9 S: 4, fringe code X: ' ' S: ' ' observation 48, WETTZ13N:WETTZELL, 0738+491, 07:24:16, quality code X: 9 S: 4, fringe code X: ' ' S: ' ' observation 78, WETTZ13N:WETTZELL, 1039+811, 07:38:09, quality code X: 9 S: 2, fringe code X: ' ' S: ' ' observation 81, WETTZ13N:WETTZELL, 1053+704, 07:39:24, quality code X: 9 S: 3, fringe code X: ' ' S: ' ' observation 90, WETTZ13N:WETTZELL, 1324+224, 07:44:34, quality code X: 9 S: 4, fringe code X: ' ' S: 'G' observation 111, WETTZ13N:WETTZELL, 0827+243, 07:53:50, quality code X: 6 S: 4, fringe code X: 'G' S: ' ' observation 114, WETTZ13N:WETTZELL, OJ287 , 07:54:54, quality code X: 9 S: 3, fringe code X: ' ' S: ' ' Number of observations rejected during analysis: 6 observation 21, WETTZ13N:WETTZELL, 1806+456, 07:08:38, which fits at 25383.2 +/- 274.7 ps observation 36, WETTZ13N:WETTZELL, 0827+243, 07:19:37, which fits at -3251.7 +/- 274.4 ps observation 51, WETTZ13N:WETTZELL, 0613+570, 07:25:35, which fits at -2439.0 +/- 274.4 ps observation 69, WETTZ13N:WETTZELL, 1842+681, 07:34:36, which fits at -25745.1 +/- 274.6 ps observation 93, WETTZ13N:WETTZELL, 1156+295, 07:46:10, which fits at -4231.3 +/- 274.4 ps observation 99, WETTZ13N:WETTZELL, 1015+359, 07:48:45, which fits at 8485.0 +/- 274.5 ps Other comments: NYALES20 did not observe due to an antenna scanning operation.
