Cutoff energy and phase lag as functions of γmin without (filled circles) and with an acceleration zone (empty circles). Each point represents a calculation with the same τ∥ = 5 and different γmin (v⊥). The horizontal dotted lines bracket the ranges of observed values as in Motta et al. (2009) for Ec and Altamirano & Méndez (2015) for φlag.
