(Analyzed by Christopher Dieck, US Naval Observatory. Spoolfile source: interactive nuSolve analysis.) Problems: FORTLEZA - Some relative humidity readings were over 100% and were set to 100%. WETTZ13N - Did not participate, out for maintenance. YARRA12M - Did not participate. Parameterization comments: - Atmospheric constraint for FORTLEZA was increased to 105 ps/h. - Baseline clock offsets were added on the following baselines: ISHIOKA :WARK12M KATH12M :WARK12M MATERA :WETTZELL NYALES20:WARK12M Other comments: None.
