Fig. 8
Hα rotation curve (vϕ, open symbols and solid line) and the epicycle anisotropy profile (βEA, dotted line) of the galaxy UGC 3809. The Hα rotation curve is from the GHASP survey (Epinat et al. 2008a,b). The solid line indicates the Einasto model of the rotation velocity. The βEA profile is deduced from the rotation model using Eq. (3). The filled circles represent βEA at R = h.
