Properties of the stellar populations of the counter-rotating components in NGC 4191. Left panels: median values of age (top panel), [Z/H] (middle panel) and [α/Fe] (bottom panel) within elliptical annuli for the main (red line) and secondary (blue line) stellar components. Right panels: two-dimensional maps of the stellar population properties. The dashed lines indicate the elliptical annuli used in computing the median values presented in the left panels. Spatial bins with S/N lower than 25 per Å are not considered in the analysis.
