From: Using Fire History Data to Map Temporal Sequences of Fire Return Intervals and Seasons
Excerpt from the MS Excel file used for calculating actual fire return intervals for five polygons (spatial groups) in the dataset. We have omitted columns that are irrelevant to the computation of the fire return intervals. Boxes represent the logical test functions that have been written to compute the values for the highlighted cell. For the logical test functions in each box, the value returned in the cell is highlighted in bold (either ‘value if true’ or ‘value if false’). Where it is ‘value if false,’ the section of the logical test that is not upheld is highlighted in bold italic.
