The average cylindrical anisotropies β z (left) and γ (right) vs. the intrinsic, average stellar ellipticity ﹩{\epsilon }_{\mathrm{intr}}﹩. The anisotropies were averaged within the sphere of radius r ≤ 0.8 kpc (∼10″) because values outside the FOV are poorly constrained by the data. Squares: the massive COMA ETGs of J. Thomas et al. (2009a). Stars: the ETGs from M. Cappellari et al. (2007). The dashed diagonal line indicates the empirical relation ﹩{\beta }_{z}=0.7\cdot {\epsilon }_{\mathrm{intr}}﹩ from M. Cappellari et al. (2007), where flatter galaxies have higher anisotropy β z .
