Differential sensitivity comparison between the current default tail-cut cleaning candidate and the best candidate for the performance criterion, TIME3D_1. The upper panel shows the curves, while the lower panel displays the inverse ratio (i.e., values larger than 1 denote a smaller, and thus improved, sensitivity). The first flux point for TIME3D_1 at E = 48.6 TeV corresponds to an improvement of 200% and is omitted from the lower panel for clarity. The blue shaded region indicates the energy range of interest for the performance criterion.
