Same as Fig. 7 with the 2.0 and 3.0 M_⊙ (blue and red, respectively) evolutionary tracks (not covering the AGB) computed with [Fe/H] = 0.0 (left) and [Fe/H] = −0.5 (right). In each panel the solid tracks correspond to the indicated metallicity, which is also used to derive the atmospheric parameters of the targets; the dashed tracks correspond to the other metallicity ([Fe/H] = −0.5 and 0.0 in the left and right panel, respectively).
