a, b Non-Gaussian parameter α2 as a function of Δγ for the ABS and BUMP systems, respectively (with the same color codes as in Fig. 2a and b). Solid curves show a fit \({\alpha }_{2}(\Delta \gamma )=B\cdot \exp [-{(\Delta \gamma /\Delta {\gamma }_{g})}^{\theta }]\), with θ = 1 (exponential) and 0.5 (stretched exponential) for ABS and BUMP, respectively. c, d Associated fit parameters as a function of Γ, demonstrating that Δγc(Γ) and Δγg(Γ) are proportional to each other. Insets: Γ-dependence of B(Γ). Error bars represent the standard deviations from different realizations for ABS, and fitting uncertainty for BUMP.
