IVS Analysis Report for I22250 ($22SEP07XU) 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: There appeared to be a clock break or similar problem resulting in five observations from 19:19:56 through 19:29:07 being offset from the other observations, fitting at ~ 30 ns in the soolution. These five observations were deselected. Number of observations rejected during correlation: 0 Number of observations not usable by the software: 11 observation 1, KOKEE :WETTZELL, 1039+811, 18:30:20, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 2, KOKEE :WETTZELL, 3C274 , 18:32:20, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 3, KOKEE :WETTZELL, 1015+359, 18:34:29, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 5, KOKEE :WETTZELL, 2229+695, 18:38:33, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 8, KOKEE :WETTZELL, 0529+483, 18:43:10, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 10, KOKEE :WETTZELL, 1418+546, 18:47:21, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 12, KOKEE :WETTZELL, 1145+268, 18:51:45, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 23, KOKEE :WETTZELL, 2353+816, 19:12:49, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 24, KOKEE :WETTZELL, 0529+483, 19:14:57, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 25, KOKEE :WETTZELL, 1418+546, 19:17:38, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 30, KOKEE :WETTZELL, 0529+483, 19:26:59, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' Number of observations rejected during analysis: 5 observation 26, KOKEE :WETTZELL, 1306+360, 19:19:56, which fits at -30017.6 +/- 62.1 ps observation 27, KOKEE :WETTZELL, 0955+476, 19:21:50, which fits at -29973.9 +/- 77.6 ps observation 28, KOKEE :WETTZELL, 0202+319, 19:23:58, which fits at -30158.7 +/- 71.3 ps observation 29, KOKEE :WETTZELL, 0133+476, 19:25:16, which fits at -30075.5 +/- 65.8 ps observation 31, KOKEE :WETTZELL, 0718+793, 19:29:07, which fits at -29954.0 +/- 87.5 ps Other comments: None.
