IVS Analysis Report for I18082 ($18MAR23XU) 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: None. Number of observations rejected during correlation: 5 The following observations were not correlated in X-band: observation at 19:12:34 on SVETLOE-WETTZELL of 1520+437 observation at 19:22:35 on SVETLOE-WETTZELL of NRAO512 observation at 19:35:41 on KOKEE-SVETLOE of 2356+385 observation at 19:35:41 on SVETLOE-WETTZELL of 2356+385 observation at 19:35:41 on NYALES20-SVETLOE of 2356+385 Number of observations not usable by the software: 12 observation 20, KOKEE :SVETLOE , 1636+473, 18:57:03, quality code X-band: 9 S-band: 0 observation 29, KOKEE :WETTZELL, NGC6251 , 19:04:24, quality code X-band: 0 S-band: 0 observation 30, KOKEE :WETTZELL, DA426 , 19:08:08, quality code X-band: 0 S-band: 9 observation 36, KOKEE :WETTZELL, 1520+437, 19:12:34, quality code X-band: 0 S-band: 9 observation 38, NYALES20:WETTZELL, 1520+437, 19:12:34, quality code X-band: 0 S-band: 9 observation 41, KOKEE :WETTZELL, 1651+391, 19:16:30, quality code X-band: 0 S-band: 0 observation 43, NYALES20:WETTZELL, 1651+391, 19:16:30, quality code X-band: 0 S-band: 0 observation 44, KOKEE :WETTZELL, 1441+252, 19:19:26, quality code X-band: 0 S-band: 0 observation 46, NYALES20:WETTZELL, 1441+252, 19:19:26, quality code X-band: 0 S-band: 0 observation 48, SVETLOE :WETTZELL, 1441+252, 19:19:26, quality code X-band: 0 S-band: 0 observation 50, KOKEE :WETTZELL, NRAO512 , 19:22:35, quality code X-band: 0 S-band: 9 observation 52, NYALES20:WETTZELL, NRAO512 , 19:22:35, quality code X-band: 0 S-band: 9 Number of observations rejected during analysis: 0 Other comments: This session has been reprocessed in order to add 12 observations that were not used in the original, automatically generated solution. Also the SVETLOE log file has become available, and weather data for SVETLOE has now been used in the solution.
