Schematic illustration of the cloud models C01 (left panel) and C02 (middle panel). Both models differ only by the position of a single star. The isocontour surface at log (n_d) = 3.27 m^-3 is in dark yellow. The direction of the common gas stream v (left panel) toward the center is shown in green lines and the analytical hourglass field morphology is shown in grey. Red lines and blue bars indicate the different angles between the radiation field and the magnetic field direction. The letters A–D indicate areas with expected characteristic features for RAT and GOLD alignment, respectively.
