Notes. ^(a,b) Values of v_sys and the r_orig coordinates when they are different from (see Table E.1) and from coordinates of the continuum peak at 1.3 mm (see Table 1), respectively. The values in parentheses represent the offset in km s⁻¹ with respect to the value and the offset in arcsec with respect to the continuum peak, respectively. The u symbol means “unchanged”: (see Table E.1) and the r_orig coordinates are still equal to coordinates of the continuum peak at 1.3 mm (see Table 1). ^(c) Index of fits by an orthogonal least-square power-law (v ∝ r^η) on the red and blue points and the reduced χ² value associated with this best-fit model. The dashes mean that no fit has been done because the tracer is not used to constrain the PV_rot diagram of this source.
