F₈-based ﹩\mathrm{log}\;g﹩ for Kepler stars in the H–R diagram. Top: simulated population from the TRILEGAL model for the Kepler field of view and down to K_p < 13.5, with evolved red giants (﹩\mathrm{log}\;g﹩ < 2.5) removed and the T_eff range restricted to 7150 K > T_eff > 4500 K to mimic the limits of the F₈ calibration. We also show evolutionary tracks for stars of various masses, indicated in units of M_⊙. Middle: same, except showing the actual F₈-based ﹩\mathrm{log}\;g﹩ for the Kepler sample. Bottom: comparison of the distributions of ﹩\mathrm{log}\;g﹩ from F₈ (red) and TRILEGAL simulation (black). The vertical dotted lines indicate the range of 3.5 < ﹩\mathrm{log}\;g﹩ < 4.1, corresponding to subgiants.
