IVS Analysis Report for V20252 ($20SEP08VI) This report is the official IVS analysis report that corresponds to the database maintained by the IVS Data Centers for this session. (Analyzed by Sergei Bolotin, NVI, Inc. / NASA Goddard Space Flight Center. Spoolfile source: interactive solve/nuSolve analysis.) Problems: WESTFORD No fringes in Y polarization due to bad optical fiber transceiver. Data included and H code threshold set to zero to mitigate effect. GGAO12M Did not observe due to gearbox replacement. MACGO12M Observed with a warm receiver. Number of observations rejected during correlation: 3 observation of 1803+784 at 18:30:00 observation of 1803+784 at 18:30:00 observation of 1803+784 at 18:30:00 Number of observations not usable by the software: 0 Number of observations rejected during analysis: 7 observation 29, KOKEE12M:WETTZ13S, 1030+415, 18:40:25, which fits at -448.7 +/- 91.2 ps observation 46, KOKEE12M:WETTZ13S, 1030+415, 18:51:12, which fits at -293.7 +/- 91.1 ps observation 62, KOKEE12M:WETTZ13S, 0529+483, 18:59:07, which fits at -323.7 +/- 90.7 ps observation 69, KOKEE12M:WETTZ13S, 1030+415, 19:04:43, which fits at -361.5 +/- 91.0 ps observation 92, KOKEE12M:WETTZ13S, 0529+483, 19:16:42, which fits at -423.7 +/- 90.7 ps observation 93, WESTFORD:WETTZ13S, 0529+483, 19:16:42, which fits at -445.9 +/- 76.2 ps observation 101, KOKEE12M:WETTZ13S, 1030+415, 19:21:26, which fits at -390.9 +/- 91.0 ps Other comments: None.
