Top: rotation velocity curve of the simulated disk (solid black line). Filled blue symbols represent the rotation curve derived from the high-resolution mock velocity field (i = 55°, see Fig. A.3 and text). The red line indicates the circular velocity curve of the simulation. Bottom: vertical-to-radial dispersion ratio (black line) and azimuthal anisotropy (green line) of the simulated disk. The dotted line indicates the azimuthal anisotropy profile predicted by Eq. (3) of the epicyclic approximation using the circular velocity curve of the simulation.
