Evolutionary tracks for models from 1.05 to 1.14 M_⊙ (from right to left) with Z_i = 0.024 and Y_i = 0.25 (left panel) and evolutionary tracks for models from 1.05 to 1.12 M_⊙ (from right to left) with Z_i = 0.024 and Y_i = 0.26 (right panel). The error boxes are those of Ramírez et al. (2009; red dashed lines), Ramírez et al. (2011; green dot-dashed lines), Schuler et al. (2011; blue dotted lines) and Tucci Maia et al. (2014; black dotted lines). The blue dots indicate models with the right large separation, taking Kjeldsen et al. (2008) corrections into account. The blue squares correspond to models that also have the right small separations and best fit the Echelle diagram. The black thick segments of each line indicate the models whose radii are consistent with the interferometric determinations of White et al. (2013).
