Lag-luminosity relation, cumulative, and differential distributions of lags for δe_p = 0.5, δa = δb = 0.1, and ⟨t_p⟩ / |C | given by Eq. (15) with γ = 0.15; left panel: 250 simulated events (red circles) and data points from Heussaff (2015; black dots); middle panel: cumulative distribution of lags; right panel: differential distribution of lags. In the middle and right panels the observed distribution is binned in interval of 10 ms.
