Fig. 12
V/σ profile of NGC 1316. The fitted rotation of the PNe is divided by the robust dispersion measurement shown in Fig. 11 to illustrate the relative dynamical importance of rotation and random motions. For NGC 1316, rotation is more important in the outer parts than it is in the inner parts. 1Re = 109′′ = 11.4 kpc (Caon et al. 1994).
