Filled circles joined by solid lines show the mean LOS velocity and velocity dispersion curves of NGC 4710 at four heights from the plane Z = 0.28, 0.56 , 0.83, and 1.12 kpc. Dashed lines show the corresponding rotation curves of the Milky Way bulge from Zoccali et al. (2014; left panels) and of a disc galaxy simulation from Cole et al. (2014; right panels). Spatial coordinates of NGC 4710 and the simulation were scaled to match the Milky Way bulge bar scale length (R_bar = 3.5 kpc). The mean velocities and velocity dispersion of NGC 4710 and the simulation were obtained in bins of 0.2 kpc at the same scale heights of the Milky Way bulge measurements using the spatial scaling factor of 0.88 and 1.2 for NGC 4710 and the simulation, respectively. Velocities of the Milky Way bulge and the simulation were scaled to match the maximum velocity of the bulge of NGC 4710.
