Top: total particle spectrum as a function of the dimensionless total particle momentum, u = γβ for all the magnetizations explored in this study and at the same time ω_pet = 3920. Bottom: effect of the striped wind filling factor on the final particle spectrum, L_s/L_y for σ₀ = 10 at the same time as in the top panel. The black dotted line shows a power law dN/du ∝ u^−p of index 2.2. The black dashed line is a 2D relativistic Maxwellian distribution for comparison.
