Notes. P.A. is the position angle of the disk rotation axis, i the inclination angle of the disk (0 means face-on), Vsyst the systemic velocity. The velocity laws (V100) are Keplerian (Piétu et al. 2007; Schaefer et al. 2009). δv is the turbulent line-width component. Derived parameters are given with their errorbars (a “ − ” means that the standard values are assumed.)
