Notes. (a) Range of radii over which the PVrot diagrams were built and the fits were performed. (b)Number of degrees of freedom we used for the modeling and reduced χ2 value associated with the best fit with a power-law function v ∝ r−1. (c) Number of degrees of freedom we used for the modeling, index of fit with a power-law function (v ∝ rα) and the reduced χ2 value associated with this best fit model.
