Results for the infinite plane-parallel slab experiment for an optical depth of τ_max = 30 and an albedo of A = 0.7. Curves represent transmission intensities obtained by either a non-probabilistic method (purple) or MC based methods (dashed curves). The latter are additionally divided into four types, depending on their usage of advanced MCRT methods, such as the stretching method (stretching) or the enforcement of a minimum scattering order (MSO). The underlaid colored areas mark the regions of all simulated intensity curves, and dashed curves of the same color represent the corresponding medians.
