Stellar population properties from the two selected apertures in the middle (left panels) and halo pointing (right panels) of FCC 167 shown in Fig. 13. Top panels: rest-frame spectra (black lines), best-fitting models (red lines), and residuals obtained by subtracting models from spectra (green points). Bottom panels: posterior distributions for the age, metallicity [M/H], and α-element abundance [Mg/Fe]. The dashed lines overplotted on the histograms indicate the 16%, 50%, and 84% percentiles of the marginalised distributions.
