Combined profiles of ρhΓ²(r, z^*, t_l, 2D) (solid blue) and Γ(r, z^*, t_l, 2D) (dash-dotted lime), where z^* corresponds to the second recollimation stage, at t_2D = 3000. The upper panel is made with setup SHC05, where the initial and boundary conditions adopt a smooth discontinuity with different opening angles for density and Lorentz factor, while the lower panel adopts a sharp discontinuity at a single opening angle.
