Notes.
The uncertainties of the kinematic parameters were derived from simulations (see Sect. 3.6).
Total ten free parameters and their 1σ uncertainties were determined from the GalPAK3D. The parameters are the xc, yc, and zc positions; the total flux in the same units as the input data cube; the disk half-light radius r1/2; the turnover radius rv; the inclination angle Incl. (the angle between the normal of the disk plane and the line-of-sight of the observer); position angle PA; the maximum circular velocity Vmax ; and the intrinsic velocity dispersion σ0.
