Waiting time (Δt), duration (T), and peak counts (P) distributions of pulses in various energy bands. (a) The cumulative distributions of Δt of pulses in various energy bands are shown in stepwise lines. The vertical dotted lines indicate the break x_b in the distributions, above which they are fitted. The best fit using Equation (2) is presented as a solid line with the 95% confidence interval between dashed lines. (b) Same as (a), but for T. (c) Same as (a), but for P. (d) The evolution of the power-law slopes for Δt as a function of energy range. The dashed line shows the prediction (2.0) of the 3D SOC model. (e) and (f) The same as (d), but for T and P, respectively. As the energy increases, the slope for Δt (d) exhibits a temporary pause at ∼150 keV but continues to decrease at higher energies up to ∼1000 keV and beyond; in contrast, the slopes for T (e) and P (f) level off and remain nearly constant from ∼150 keV upward.
