SAM radial profiles computed through the equatorial plane for nonturbulent (upper row) and turbulent (lower row) models. The first column shows the profiles from the models, while the second to last columns show the profiles from synthetic observations of the models, using different techniques to measure the rotational velocities (see Sect. 3). More (μ = 3.33) and less (μ = 10) magnetized models are depicted with dotted and solid lines, respectively. Different evolutionary states are represented on a color scale: black, blue, and red for protostellar masses equal to ~0.06/0.07, 0.18, and 0.30 M_⊙, respectively. The shaded gray area represents the region that cannot be sampled because it lies below the velocity resolution of synthetic observations (0.06 km s⁻¹).
