Fig. 11.
Line-strength index maps and radial profiles for NGC 448. Left panels: 2D maps of the index strengths of the counter-rotating component of Hβ, Mg b/⟨Fe⟩, [MgFe]′, and Na D from top to bottom, respectively. Middle panels: Same 2D maps of the index strengths, but for the main component. Right panels: index radial profiles taking elliptical annuli as for the counter-rotating (red) and main stellar (blue) kinematic components. The error bars represent the resistant standard deviation of the measurements within a given annulus.
