We also used several other thresholds for the cliffs, i.e., (Formula presented) and (Formula presented), and find that the most probable cliff width is always around (Formula presented) but the most probable amplitude shifts to higher values when the threshold is increased since events of lower “intensity” are excluded. The shapes of the various histograms also remain invariant for different thresholds.
