$^{{\rm a}}$
Derived with the method in Anderson et al. (2003).
$^{{\rm b}}$
Keplerian velocity at the footpoints r₀.
$^{{\rm c}}$
Imposing that $\vert B_{\phi}\vert=0$ at the location of the observations and adopting the scalings in Ferreira & Pelletier (1993) (see text).
$^{{\rm d}}$
Considering only the portion of the disk from where the outflow seen at optical wavelengths originates.
$^{{\rm e}}$
Assuming dominant magnetic torque; accuracy 20-22%.
$^{{\rm f}}$
At about 80 AU above the disk and 30 (20) AU from the axis for the red (blue) lobe. Coordinate system as in Table 3.
