Simulation statistics and performance of the simulation study when the SNR is 10 dB. Results are quantified using the following measures, localization error, AUC and the ratio of the area of the overlap between the estimated and true source to either the area of the true source or the area of the estimated source. The statistics are shown in the left panel. In the right panel, the relation between the extent of the estimated and simulated source is delineated (top row). Two different source sizes namely, 10 mm and 15 mm, were simulated and the results are depicted in the right panel (bottom row).
