Areas are sums of 40 × 40 m cells. Nationally the cell sums run 0.3–0.5% above the original polygon areas (measured per scenario); the error is larger for small townships. A scenario is a design rainfall: total over the duration, not per hour. The depth class is the maximum simulated depth in the cell.
