Fig. 4

Same as the lower panel of Fig. 3, but for two ages – 8 and 12 Gyr – and three different chemical compositions. The solid lines show the LFs at solar chemical composition, while the dotted-dashed and long-dashed lines display the α-enhanced ([α/Fe] = 0.4) LFs for two more metal-poor chemical compositions, [Fe/H] = −0.7 and [Fe/H] = −2.1.
