IVS Analysis Report for R4899 ($19JUN20XE) This report is the official IVS analysis report that corresponds 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: BADARY - Missed scans between 172-0755 and 172-0922 due to bad weather and power outages. NYALES20 - Observed with warm receiver. YEBES40M - Had poor cable cal data, which was turned off anyway because a manual phase cal was applied. Parameterization comments: - Atmospheric constraint for ISHIOKA was increased to 85 ps/hr. - Clock constraint for YARRA12M was increased to 207 ps/hr. - Baseline clock offsets were added on the following baselines: MEDICINA:NYALES20 Other comments: - Analysis of re-released database. - Due to dropped channels, the S-band ambiguity spacing is 50 ns on all YEBES40M baselines.
