Velocity dispersion maps in the V_max-anisotropy space. Left, central and right panels: velocity dispersions in the projected radial, tangential and in the LOS components, respectively. Black solid lines and coloured-shaded areas indicate the range defined by our mean measurements and their 16th and 84th percentiles, at R_HST. Coloured lines indicate contours of constant dispersion in steps of 0.5 km s⁻¹.
