IVS Analysis Report for V21348 ($21DEC14VI) 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: The WETTZ13S operator noted that the az/el axes stopped at 348-1910. The correlator report noted that no fringes were found after scan 348-1909. The final 14 observations were lost due to this problem. Number of observations rejected during correlation: 0 Number of observations not usable by the software: 4 observation 253, ISHIOKA :NYALE13S, NRAO150 , 07:47:08, quality code X: 9 S: 0, fringe code X: ' ' S: ' ' observation 258, NYALE13S:SESHAN25, NRAO150 , 07:47:08, quality code X: 9 S: 0, fringe code X: ' ' S: ' ' observation 260, NYALES20:SESHAN25, NRAO150 , 07:47:08, quality code X: 8 S: 0, fringe code X: ' ' S: ' ' observation 262, SESHAN25:WETTZELL, NRAO150 , 07:47:08, quality code X: 8 S: 0, fringe code X: ' ' S: ' ' Number of observations rejected during analysis: 3 observation 117, NYALE13S:NYALES20, 2229+695, 07:22:59, which fits at 1565.2 +/- 40.9 ps observation 187, NYALE13S:NYALES20, 1726+455, 07:34:29, which fits at -508.4 +/- 37.3 ps observation 267, NYALE13S:NYALES20, 0613+570, 07:48:41, which fits at -1900.9 +/- 31.5 ps Other comments: None.
