IVS Analysis Report for I22147 ($22MAY27XU) 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: A clock break seems to have occurred around 19:33:00. There were only four observations after the break (the observations from 19:34:13 through 19:44:01), and this is probably not enough to support a post-break solution. So these four observations were excluded. Also, the observation at 19:30:44 fit at ~ 35 ns in S-band, so it was deselected. Number of observations rejected during correlation: 0 Number of observations not usable by the software: 0 Number of observations rejected during analysis: 5 observation 15, KOKEE :WETTZELL, 0059+581, 19:30:47, which fits at 3809.1 +/- 58.5 ps observation 16, KOKEE :WETTZELL, 2353+816, 19:34:13, which fits at -20163.7 +/- 73.1 ps observation 17, KOKEE :WETTZELL, 0642+449, 19:37:32, which fits at -19873.8 +/- 62.4 ps observation 18, KOKEE :WETTZELL, 2229+695, 19:40:58, which fits at -20161.7 +/- 69.2 ps observation 19, KOKEE :WETTZELL, 1039+811, 19:44:01, which fits at -20269.0 +/- 72.7 ps Other comments: None.
