The fraction of the old (red) and young (blue) stellar populations to the mean unattenuated (/Lbol; left panel) and to the mean attenuated luminosity (/Lbol; right panel), to the bolometric luminosity, per galaxy subset. In the right panel the ratio of the mean dust luminosity over the bolometric luminosity is also shown in orange colour (fabs = Ldust/Lbol).
