USNO Analysis Report for W20055 ($20FEB24XW) This report is a contributed analysis report that does not correspond to the database maintained by the IVS Data Centers for this session. (Analyzed by Christopher Dieck, US Naval Observatory. Spoolfile source: interactive nuSolve analysis.) Problems: - Numerous 0-codes on S-band, largely at PIETOWN. - MK-VLBA channels XR3U and XR4U were removed from fringe fitting. - There were sub-ambiguities on PIETOWN:WETTZ13N. After deselection of the sub-ambiguities, there were not enough observations to allow for a solution, so the baseline was deselected. Number of observations rejected during correlation: 0 Number of observations not usable by the software: 61 observation 3, PIETOWN :WETTZ13N, 1803+784, 08:30:20, quality codes - S:9, X:8 observation 5, MK-VLBA :WETTZ13N, 0415+398, 08:32:54, quality codes -
