Caption: Figure 12.

The Alfvén Mach number from the SVS 13A magnetic field map is shown in a color scale. The color white represents the trans-Alfvénic value of ﹩{{ \mathcal M }}_{{\rm{A}}}=1﹩, while red indicates the sub-Alfvénic regime. The magnetic field morphology is superposed as white pseudovectors plotted every 5 pixels. The map was produced from the data imaged using robust = 1. The beam is depicted as a blue ellipse in the bottom left corner, and the scale is displayed in the bottom right corner.
