Mass-weighted and luminosity-weighted mean values of stellar age and metallicity for all structural components in NGC 4371. The structural components are arranged along the x-axis such that this axis can be thought of as the galactocentric distance, i.e. the point source component is at the centre of the galaxy, and to the right side of it we arranged the other components that dominate the emission from the galaxy at successively larger distances. The error bars are an outlier-resistant measure of the dispersion about the mean, analogous to the standard deviation.
