Spectral index Dn(4000) for individual spaxel as a function of radius for our sample of galaxies. The grey circles denote the spaxels of the high-metallicity regions, the red plus signs are the spaxels of the low-metallicity regions. The dashed line marks Dn(4000) = 1.42, and the dotted line shows Dn(4000) = 1.3 (see text).
