| The ideal table is one in which all diagonal values are 1 and all other values are 0. Thus two values, Bray-Curtis similarity and Root-mean-square deviation (RBSD), are computed between the diagonal of the overall heat table and the diagonal of the ideal table. The the software gives a suggestion to the user based on these two values about whether to stop/continue the iterative process. Right now the threshold to stop the iteration is set to the case: in the overall table, every diagonal value is 90% (i.e. the overlap between each polygon in the current plume and the corresponding polygon in the old plume accounts for 90% of the area of either polygon). In this case, the Bray-Curtis similarity value is 18/19, which is the minimum threshold; the RBSD is 0.1, which is the maximum threshold. Right now as long as one of these two statistical values meets the threshold, then the software recommends to stop the iteration. | The ideal situation for stopping the iteration process is that the two Kriging results are identical, implying that all diagonal values of each table are 1 and all other values are 0.
