Rate of false positives over all positives as a function of their seismic signature. Each data point represents the ratio of false positives in the ranges [P_i − 10, P_i + 10] (FarNet, top row) and [S − 25, S + 25] (standard seismic method, bottom row), with P_i and S given by the value in the horizontal axis. Each column represents the comparison results for the studies done with 24 h (first column), 72 h (second column), and 120 h (third column) of STEREO data.
