Line profiles predicted by RADMC-3D for ¹³CO (1 → 0) for two faces of the cube and three lines of sight. The solid black line corresponds to the post-processed simulation, which assuming a nominal distance of d = 140 pc corresponds to a scale of 0.28″ per cell; the dashed grey line corresponds to the line profile convolved to the IRAM 30 m resolution for the selected transition, which is 22.32″. The difference in velocity range for both the upper and lower panels, which corresponds to lines of sight perpendicular (xy plane, left panel in Fig. 3) and parallel to the magnetic field (yz plane, right panel in Fig. 3) respectively.
