Additional file 2: Figure S2. Frequency distribution of the optimum parameter combinations in TROP and GRAD parameter space, based on data from the entire GEONET network on November 22, 2011. Regions indicated by the dashed red squares denote the high-frequency region in each component. Dashed black squares denote the second peak of the high-frequency distribution of the optimum parameter combinations. The colors indicate the ratio of the frequency within each combination of the parameters relative to the number of GEONET sites. The solid squares indicated the optimum combination value in each component.
