IVS Analysis Report for Q21214 ($21AUG02XK) 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: Five ISHIOKA scans failed due to trouble with its antenna EL drive. These scans were observed, but they were not usable by the analysis software. More details about this issue and other issues are given in the other comments section. Number of observations rejected during correlation: 0 Number of observations not usable by the software: 41 observation 4, NYALE13S:NYALES20, 2000+472, 07:00:20, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 7, ISHIOKA :NYALE13S, 3C371 , 07:01:36, quality code X: 9 S: 0, fringe code X: ' ' S: ' ' observation 8, ISHIOKA :NYALES20, 3C371 , 07:01:36, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 37, ISHIOKA :NYALE13S, 1726+455, 07:08:07, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 38, ISHIOKA :NYALES20, 1726+455, 07:08:07, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 39, ISHIOKA :WETTZELL, 1726+455, 07:08:07, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 40, NYALE13S:NYALES20, 1726+455, 07:08:07, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 41, NYALE13S:WETTZELL, 1726+455, 07:08:07, quality code X: 9 S: 0, fringe code X: ' ' S: ' ' observation 42, NYALES20:WETTZELL, 1726+455, 07:08:07, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 44, ISHIOKA :NYALES20, 2229+695, 07:09:39, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 46, NYALE13S:NYALES20, 2229+695, 07:09:39, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 56, ISHIOKA :NYALES20, 0016+731, 07:12:00, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 62, ISHIOKA :NYALES20, 0552+398, 07:13:59, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 74, ISHIOKA :NYALES20, 0955+476, 07:16:27, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 86, ISHIOKA :NYALES20, 0642+449, 07:19:22, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 92, ISHIOKA :NYALES20, 0529+483, 07:20:34, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 110, ISHIOKA :NYALES20, 1059+282, 07:25:04, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 112, NYALE13S:NYALES20, 1059+282, 07:25:04, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 140, ISHIOKA :NYALES20, 3C371 , 07:31:08, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 152, ISHIOKA :NYALES20, 2229+695, 07:33:28, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 158, ISHIOKA :NYALES20, 2000+472, 07:34:42, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 164, ISHIOKA :NYALES20, 0016+731, 07:36:04, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 169, ISHIOKA :NYALE13S, 1849+670, 07:37:50, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 170, ISHIOKA :NYALES20, 1849+670, 07:37:50, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 171, ISHIOKA :WETTZELL, 1849+670, 07:37:50, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 175, ISHIOKA :NYALE13S, 0955+476, 07:40:03, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 176, ISHIOKA :NYALES20, 0955+476, 07:40:03, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 177, ISHIOKA :WETTZELL, 0955+476, 07:40:03, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 182, ISHIOKA :NYALES20, 0814+425, 07:41:16, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 188, ISHIOKA :NYALES20, 0642+449, 07:42:26, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 194, ISHIOKA :NYALES20, 0529+483, 07:43:38, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 224, ISHIOKA :NYALES20, 1059+282, 07:50:34, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 226, NYALE13S:NYALES20, 1059+282, 07:50:34, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 241, ISHIOKA :NYALE13S, 3C371 , 07:54:40, quality code X: 9 S: 0, fringe code X: ' ' S: ' ' observation 242, ISHIOKA :NYALES20, 3C371 , 07:54:40, quality code X: 0 S: 9, fringe code X: ' ' S: ' ' observation 253, ISHIOKA :NYALE13S, 2229+695, 07:57:00, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 254, ISHIOKA :NYALES20, 2229+695, 07:57:00, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 255, ISHIOKA :WETTZELL, 2229+695, 07:57:00, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 259, ISHIOKA :NYALE13S, 0016+731, 07:58:08, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 260, ISHIOKA :NYALES20, 0016+731, 07:58:08, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' observation 261, ISHIOKA :WETTZELL, 0016+731, 07:58:08, quality code X: 0 S: 0, fringe code X: ' ' S: ' ' Number of observations rejected during analysis: 3 observation 205, ISHIOKA :NYALE13S, 0748+126, 07:46:38, which fits at 235.0 +/- 76.6 ps observation 207, ISHIOKA :WETTZELL, 0748+126, 07:46:38, which fits at 292.2 +/- 56.0 ps observation 225, ISHIOKA :WETTZELL, 1059+282, 07:50:34, which fits at 393.4 +/- 85.3 ps Other comments: The correlator report's station notes included the following information: ISHIOKA (Is/Q): Missed 5 scans due to antenna EL drive trouble: 214-0737 , 214-0739 , 214-0755 , 214-0756 and 214-0757. Some non-detections, particularly in X-band on baseline Is-Ny. NYALE13S (Ns/w): A few non-detections in both bands. NYALES20 (Ny/N): Some non-detections in both bands, particularly in X-band on baseline Is-Ny. WETTZELL (Wz/V): A few non-detections. The correlator report did not explicitly mention the clock problems seen recently at NYALES20, but the clock section of the correlator report indicated that an a priori clock offset and rate should be applied. The values from the clock section were used (an offset of -71919.73 usec and a rate of -2.261E-08 sec/sec). The NYALE13S station coordinates were estimated because NYALES13S is still a relatively new station.
