The waiting time distribution for the bursts simulated with the Poisson process. The three panels correspond to burst rates of 2.5, 5.0, and 10.0 bursts per second, respectively. The red curves show the waiting time distributions of all bursts generated by the Poisson process, whereas the blue curves show the results after burst selection using MESPA. As shown in the figure, the burst sample identified by MESPA tends to make the waiting time distribution closer to an exponential distribution rather than a power-law form.
