(V/σ, ε)_e (left) and (λ_Re, ε) (right) relations for the CALIFA sample of 300 galaxies. Galaxies are color-coded with Hubble type as indicated by the colorbar. For reference, we plot the ATLAS^3D sample with gray crosses. The solid line demarcates the division between Slow and Fast rotators as established by Emsellem et al. (2011). The dashed line in the right panel marks the revised division between Slow and Fast rotators defined by Cappellari (2016).
