Age and metallicity radial distributions in terms of the semi-major axis a in degrees, as done in Paper I. Age distributions are shown separately for the four components in the left panel, and the equivalent for metallicity is displayed in the right panel. Ages and metallicities are weighted averages from literature data as explained in the text. No results from this work are included here. Contours are the density maps considering a two-dimensional Gaussian around each point using their uncertainties. See text for details.
