IVS Analysis Report for Q21256 ($21SEP13XK) 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: NYALES13S could not observe due to technical problems. Due to a problem with its antenna moter, ISHIOKA stopped obeserving after 256-0741. SESHAN25 experienced some RFI. Number of observations rejected during correlation: 12 ISHIOKA failed to observe the following observations due to a problem with its antenna motor: observation of 1324+224 at 07:51:34 by ISHIOKA :SESHAN25 observation of 1324+224 at 07:51:34 by ISHIOKA :WETTZELL observation of 1308+328 at 07:52:57 by ISHIOKA :SESHAN25 observation of 1308+328 at 07:52:57 by ISHIOKA :WETTZELL observation of 1417+385 at 07:54:24 by ISHIOKA :SESHAN25 observation of 1417+385 at 07:54:24 by ISHIOKA :WETTZELL observation of 1418+546 at 07:56:01 by ISHIOKA :SESHAN25 observation of 1418+546 at 07:56:01 by ISHIOKA :WETTZELL observation of 3C371 at 07:57:43 by ISHIOKA :SESHAN25 observation of 3C371 at 07:57:43 by ISHIOKA :WETTZELL observation of 1849+670 at 07:58:47 by ISHIOKA :SESHAN25 observation of 1849+670 at 07:58:47 by ISHIOKA :WETTZELL Number of observations not usable by the software: 21 observation 14, ISHIOKA :SESHAN25, 0955+476, 07:06:53, quality code X: 8 S: 3, fringe code X: ' ' S: 'G' observation 27, ISHIOKA :SESHAN25, 1803+784, 07:13:40, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 28, ISHIOKA :WETTZELL, 1803+784, 07:13:40, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 30, ISHIOKA :SESHAN25, 3C371 , 07:14:48, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 31, ISHIOKA :WETTZELL, 3C371 , 07:14:48, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 33, ISHIOKA :SESHAN25, 1849+670, 07:15:51, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 34, ISHIOKA :WETTZELL, 1849+670, 07:15:51, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 40, ISHIOKA :WETTZELL, 3C274 , 07:21:49, quality code X: 9 S: 0, fringe code X: ' ' S: ' ' observation 41, SESHAN25:WETTZELL, 3C274 , 07:21:49, quality code X: 9 S: 0, fringe code X: ' ' S: ' ' observation 63, ISHIOKA :SESHAN25, 1053+704, 07:32:15, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 64, ISHIOKA :WETTZELL, 1053+704, 07:32:15, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 78, ISHIOKA :SESHAN25, 0718+793, 07:39:32, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 79, ISHIOKA :WETTZELL, 0718+793, 07:39:32, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 81, ISHIOKA :SESHAN25, 0716+714, 07:40:43, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 82, ISHIOKA :WETTZELL, 0716+714, 07:40:43, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 84, ISHIOKA :SESHAN25, 0738+491, 07:42:04, quality code X: 9 S: 0, fringe code X: ' ' S: ' ' observation 93, ISHIOKA :SESHAN25, 1059+282, 07:48:49, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 94, ISHIOKA :WETTZELL, 1059+282, 07:48:49, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 96, ISHIOKA :SESHAN25, 3C274 , 07:50:19, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 97, ISHIOKA :WETTZELL, 3C274 , 07:50:19, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 98, SESHAN25:WETTZELL, 3C274 , 07:50:19, quality code X: 9 S: 0, fringe code X: ' ' S: ' ' Number of observations rejected during analysis: 0 Other comments: The correlator report provided the following station notes: ISHIOKA (Is/Q): Due to antenna motor trouble, Ishioka stopped observation after 256-0741 for the safety of the antenna. 15 scans missed in total. NYALE13S (Ns/w): Station could not observe due to technical problems. SESHAN25 (Sh/C): RFI in S-band particualry affecting channel SR5U; channel removed from fringe fitting. WETTZELL (Wz/V): Ok. Although the station notes indicated that ISHIOKA missed 15 scans, the sked file only indicated 13 scans at the end of the schedule starting at 07:41. Also some of the missed scans were not correlated, but others were correlated with low quality codes.
