Violin plots showing distributions of broken power law parameters for a given shift in t₀. The dotted lines show the simulated values of these parameters for a given t₀ shift. All values are subject to variation due to these t₀ shifts. Top: Distributions for the Si II velocity at the break, A. Second from top: Distributions for the pre-break power law index, α₁. Second from bottom: Distributions for the post-break power law index, α₂. Bottom: Distributions for the break time, t_b.
