Fig. 28.
Gas velocity dispersion. Top panel: observed VIVA H I velocity dispersion (moment 2). Middle panel: velocity dispersion (moment 2) of the dynamical model. Bottom panel: intrinsic 3D velocity dispersion. The pink circle corresponds to the high H I surface density region. The red rectangle corresponds to the external gas arm. Contours correspond to H I surface densities of ΣHI = 5, 10, 20 and 50 M⊙ pc−2.
