Upper panel: in color scale, we show the AM map between the inferred magnetic field and the total intensity gradient orientation. Superposed is the magnetic field morphology onto the plane of the sky as white pseudovectors plotted every 5 pixels, which is approximately Nyquist sampling. In contours, we show the continuum emission with levels following Figure 5. Lower panel: same as the upper panel, but here we show the AM map between the field and the velocity gradient orientation. The size of the beam is shown as a blue ellipse in the bottom left corner, and the scale is shown at the bottom right corner in each panel.
