Examples of four categories of galaxies with varied stellar kinematics and nuclear surface brightness profiles. In each panel, circular symbols show the nuclear surface brightness obtained in the same way as those in Figs. 1 and 2. The solid lines represent the Nuker fits with the gradient γ′ as given in the legend. Profiles and the Nuker fits for NGC 3379, NGC 3377, and NGC 4406 (data for this galaxy are from Ferrarese et al. 2006) are taken from Krajnović et al. (2013b), while data for NGC 3522 are from the present paper. The insets show respective velocity maps, demonstrating the level of regularity and some specific kinematic structures. The colour bars show the range of velocities, which are kept the same for all galaxies for comparison. Legends also provide details on the projected ellipticity and λ_Re, taken from Emsellem et al. (2011). The two fast rotators (left column) are characterised with regular rotation. The two slow rotators (right column) exhibit a KDC (top) and a CRC (bottom). The CRC in NGC 3522 has a peak rotation of only about 20 km s⁻¹ and is located within the central 5″ (Krajnović et al. 2011).
