USNO Analysis Report for Q22316 ($22NOV12XK) 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: - Not all baselines had a mean of the post-fit residuals that was close to zero. To correct this issue, a baseline clock offset was added to the ISHIOKA:MK-VLBA, the baseline with the non-reference stations. This fix was applied in nuSolve and is saved in the USNO version of the vgosDb, but the baseline clock offset is ignored in the Solve based calculation which creates the record in the USNO EOPI file. - There were S-band subambiguities on ISHIOKA baselines.
