IVS Analysis Report for I22038 ($22FEB07XU) 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: Wettzell lost scans from 18:30 to 18:58 UTC due to network troubles. This resulted in only nine usable observations and a high UT1 formal error. Number of observations rejected during correlation: 11 observation of 1128+385 at 18:30:00 observation of 2113+293 at 18:32:15 observation of 0016+731 at 18:34:18 observation of 3C371 at 18:35:51 observation of 1053+815 at 18:37:08 observation of 1418+546 at 18:41:10 observation of NGC6251 at 18:43:07 observation of 2319+317 at 18:47:14 observation of 2229+695 at 18:51:23 observation of 0718+793 at 18:53:10 observation of 1803+784 at 18:57:08 Number of observations not usable by the software: 2 observation 3, KOKEE :WETTZELL, 0059+581, 19:07:31, quality code X: 9 S: 0, fringe code X: ' ' S: ' ' observation 7, KOKEE :WETTZELL, 0059+581, 19:19:33, quality code X: 7 S: 0, fringe code X: ' ' S: ' ' Number of observations rejected during analysis: 0 Other comments: None.
