IVS Analysis Report for Q19175 ($19JUN24XK) 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 SESHAN25 baselines were noisy, with some residuals above one nanosecond. Removal of the baselines had little effect on the UT1 adjustment and formal error, so the baselines were used in the solution. Number of observations rejected during correlation: 9 observations of 2229+695 at 07:07:10 by ISHIOKA:SESHAN25, NYALES20:SESHAN25 and SESHAN25:WETTZELL observations of 0016+731 at 07:08:13 by ISHIOKA:SESHAN25, NYALES20:SESHAN25 and SESHAN25:WETTZELL observations of 0059+581 at 07:09:19 by ISHIOKA:SESHAN25, NYALES20:SESHAN25 and SESHAN25:WETTZELL Number of observations not usable by the software: 13 observation 14, ISHIOKA :SESHAN25, 3C371 , 07:03:51, quality code X-band: 0 S-band: 0 observation 16, NYALES20:SESHAN25, 3C371 , 07:03:51, quality code X-band: 0 S-band: 0 observation 18, SESHAN25:WETTZELL, 3C371 , 07:03:51, quality code X-band: 0 S-band: 0 observation 20, ISHIOKA :SESHAN25, 1803+784, 07:04:52, quality code X-band: 0 S-band: 0 observation 22, NYALES20:SESHAN25, 1803+784, 07:04:52, quality code X-band: 0 S-band: 0 observation 24, SESHAN25:WETTZELL, 1803+784, 07:04:52, quality code X-band: 0 S-band: 0 observation 26, ISHIOKA :SESHAN25, 1849+670, 07:06:06, quality code X-band: 0 S-band: 0 observation 28, NYALES20:SESHAN25, 1849+670, 07:06:06, quality code X-band: 0 S-band: 0 observation 30, SESHAN25:WETTZELL, 1849+670, 07:06:06, quality code X-band: 0 S-band: 0 observation 94, NYALES20:SESHAN25, 0506+101, 07:25:31, quality code X-band: 0 S-band: 9 observation 166, NYALES20:SESHAN25, 1300+580, 07:43:24, quality code X-band: 0 S-band: 9 observation 175, ISHIOKA :NYALES20, 1053+815, 07:45:50, quality code X-band: 0 S-band: 9 observation 178, NYALES20:SESHAN25, 1053+815, 07:45:50, quality code X-band: 0 S-band: 9 Number of observations rejected during analysis: 2 observation 10, ISHIOKA :NYALES20, 1806+456, 07:02:47, which fits at -369.0 +/- 89.5 ps observation 11, ISHIOKA :WETTZELL, 1806+456, 07:02:47, which fits at -350.9 +/- 69.8 ps Other comments: The correlator report provided the following station notes: ISHIOKA (Is/Q): RFI in S-band.
