HEC-style labeling: the 0.05 column is commonly the upper bound and 0.95 is the lower bound (exceedance probability labels).
Ready.
Notes:
• Return period T is converted to percent chance exceedance = 100/T.
• Best fit is based on Weibull plotting positions comparing observed vs fitted quantiles.
• No bold text is used except the page title.
