Maps of kinematic and stellar population parameters for the four galaxies in our sample. Top row: Hβ emission-line fluxes in log scale. For NGC 1097, NGC 5248, and NGC 1300, we overlay the flux level that defines the nuclear ring. These isophotes are also indicated in the other panels for reference, but not in NGC 4643 since there is no evidence for a ring in this galaxy and it is used as a control galaxy. Second and third rows: maps of the difference in line-of-sight velocity and velocity dispersion between the two spectral ranges used in our study (i.e. Hβ−Ca II). Bottom row: maps for the mean luminosity-weighted age from the analysis performed by Bittner et al. (2020).
