IVS Analysis Report for I18277 ($18OCT04XU) 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: This session was recorrelated to add the data from SVETLOE. But the correlator was only able to correlate three SVETLOE---WETTZELL observations, so that baseline had to be deselected. Also, although the KOKEE---SVETLOE baseline could be included, it only had five usable observations. The KOKEE---WETTZELL baseline had the most data (13 observations). Number of observations rejected during correlation: 7 KOKEE :SVETLOE , 1803+784, 18:30:20 --- not correlated in S-band SVETLOE :WETTZELL, 1803+784, 18:30:20 --- not correlated in S-band SVETLOE :WETTZELL, 1144+402, 18:35:17 --- not correlated in S-band SVETLOE :WETTZELL, 0716+714, 18:40:01 --- not correlated in S-band SVETLOE :WETTZELL, 1441+252, 18:56:08 --- not correlated in S-band SVETLOE :WETTZELL, 1441+252, 19:19:50 --- not correlated in S-band SVETLOE :WETTZELL, 0016+731, 19:26:52 --- not correlated in S-band Number of observations not usable by the software: 8 observation 17, KOKEE :SVETLOE , 1441+252, 18:56:08, quality code X-band: 0 S-band: 0 observation 18, KOKEE :WETTZELL, 1441+252, 18:56:08, quality code X-band: 0 S-band: 9 observation 20, KOKEE :WETTZELL, 1300+580, 19:00:15, quality code X-band: 0 S-band: 9 observation 25, KOKEE :SVETLOE , 0415+398, 19:11:07, quality code X-band: 0 S-band: 9 observation 26, KOKEE :WETTZELL, 0415+398, 19:11:07, quality code X-band: 0 S-band: 9 observation 28, KOKEE :WETTZELL, 1300+580, 19:15:42, quality code X-band: 0 S-band: 9 observation 29, KOKEE :SVETLOE , 1441+252, 19:19:50, quality code X-band: 0 S-band: 0 observation 30, KOKEE :WETTZELL, 1441+252, 19:19:50, quality code X-band: 0 S-band: 9 Number of observations rejected during analysis: 3 The following three SVETLOE :WETTZELL observations were the only usable observations for that baseline, so they had to be deselected. observation 15, SVETLOE :WETTZELL, 0307+380, 18:47:26 observation 23, SVETLOE :WETTZELL, 0307+380, 19:04:50 observation 27, SVETLOE :WETTZELL, 0415+398, 19:11:07 Other comments: None.
