Notes. (1) Hubble type as listed in the LEDA data base (URL: http://leda.univ-lyon1.fr/). (2) Distance according to Walter et al. (2008). (3) Peak of the rotation curve as obtained from the Appendix in de Blok et al. (2008). (4) R₂₅ is the B-band isophotal radius at 25 mag arcsec^-2, which is a standard proxy for the optical radius of the galaxy. (5) Total HI mass of the galaxy, obtained by integrating over all pixels, see also Table 4 of Leroy et al. (2008).  (6) Total star formation rate of the galaxy, as provided by Table 1 of Walter et al. (2008) or Table 4 of Leroy et al. (2008). (7) Surface-density weighted 3-dimensional mean velocity dispersion in the galaxy. (8) Mean HI surface density. (9) Typical outer scale of the turbulent velocity field. is calculated from the disk thickness in each pixel as with and then averaged over the entire galaxy using surface-density weighting.  (10) Estimate of the mean turbulent dissipation scale based on the disk thickness derived from the potential method, Eq. (13).
