  1. All probability parameters were simulated uniformly over the range 0–1. Search radius was simulated uniformly over the range 1–1500. Each row represents the average of all catchment area results meeting the specified parameter range criteria. 80% credible intervals ranging from the 10th to the 90th quantiles of the averaged simulations are included in parentheses
