Radial metallicity profiles for the galaxies. The small dots are the individual bins from the Voronoi binned cubes, crosses are the NSCs, and triangles are the different extraction radii described in the legend and Table 2. All symbols are colour-coded by age (see colour scale at top right). Galaxies are ordered by increasing stellar mass from top left to bottom right. FCC 227 and FCC 215 are too faint to be binned.
