Distribution of min(F_i, F_i + 1) vs t_i + 1 − t_i for the simulated 100 and 300 MeV samples (left and right plot, respectively). For the 300 MeV sample the flux was scaled to match the flux for gamma rays above 100 MeV (a power-law flux with photon index of 2.23 is assumed). The solid line is the sensitivity limit for a flare from the bright source 3C 454.3 with FWHM twice the waiting times t_i + 1 − t_i. The dashed line is the temporal resolving power.
