IVS Analysis Report for I20337 ($20DEC02XU) 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: Only five SVETLOE observations were used in this solution. 10 of the KOKEE:SVETLOE observations were unusable by the software because they had X-band quality codes of zero. The remaining four observations formed an extremely noisy baseline, so KOKEE:SVETLOE was deselected. In addition, nine SVETLOE:WETTZELL observations had large residuals and were excluded from the solution. Number of observations rejected during correlation: 0 Number of observations not usable by the software: 13 observation 1, KOKEE :SVETLOE , 3C371 , 18:30:20, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 2, KOKEE :WETTZELL, 3C371 , 18:30:20, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 5, KOKEE :SVETLOE , 0641+392, 18:35:59, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 6, KOKEE :WETTZELL, 0641+392, 18:35:59, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 9, KOKEE :SVETLOE , NRAO512 , 18:40:55, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 12, KOKEE :SVETLOE , 1758+388, 18:45:18, quality code X: 0 S: 9, fringe code X: ' ' S: 'H' observation 18, KOKEE :SVETLOE , 0613+570, 18:53:14, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 21, KOKEE :SVETLOE , 0955+476, 18:57:13, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 24, KOKEE :SVETLOE , 0749+540, 19:00:26, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 36, KOKEE :SVETLOE , 0749+540, 19:18:14, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 40, KOKEE :SVETLOE , NRAO512 , 19:25:52, quality code X: 0 S: 8, fringe code X: ' ' S: ' ' observation 43, KOKEE :SVETLOE , 3C371 , 19:29:56, quality code X: 0 S: 8, fringe code X: ' ' S: 'H' observation 44, KOKEE :WETTZELL, 3C371 , 19:29:56, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' Number of observations rejected during analysis: 13 The only four usable KOKEE:SVETLOE observations were deselected because the baseline was too noisy: observation 15, KOKEE :SVETLOE , 1418+546, 18:49:29 observation 27, KOKEE :SVETLOE , 1418+546, 19:04:38 observation 30, KOKEE :SVETLOE , 0613+570, 19:08:22 observation 33, KOKEE :SVETLOE , 1746+470, 19:13:12 The following additional observations were rejected because of large residuals: observation 7, SVETLOE :WETTZELL, 0641+392, 18:35:59, which fits at 10409.2 +/- 561.2 ps observation 14, SVETLOE :WETTZELL, 1758+388, 18:45:18, which fits at -9549.3 +/- 562.0 ps observation 17, SVETLOE :WETTZELL, 1418+546, 18:49:29, which fits at 9070.3 +/- 560.9 ps observation 20, SVETLOE :WETTZELL, 0613+570, 18:53:14, which fits at -11875.9 +/- 561.3 ps observation 23, SVETLOE :WETTZELL, 0955+476, 18:57:13, which fits at 2151.6 +/- 561.3 ps observation 32, SVETLOE :WETTZELL, 0613+570, 19:08:22, which fits at 8181.5 +/- 561.0 ps observation 38, SVETLOE :WETTZELL, 0749+540, 19:18:14, which fits at 21169.2 +/- 562.0 ps observation 42, SVETLOE :WETTZELL, NRAO512 , 19:25:52, which fits at 42032.2 +/- 563.5 ps observation 45, SVETLOE :WETTZELL, 3C371 , 19:29:56, which fits at 11379.1 +/- 561.0 ps Other comments: None.
