Left: stellar evolutionary tracks in a sHR diagram color coded according to the maximum fraction of P_turb/P (see top bar). Overplotted are the location of 56 stars analyzed by Carney et al. (2008), Fossati et al. (2011), Doyle et al. (2014), and Ryabchikova et al. (2015) for which macroturbulent velocities are available, in addition to those listed in Table A.1. The five stars color coded in blue are bona fide γ Dor pulsators. Right: as in left panel, with overplotted the location of ≈300 γ Dor stars analyzed by Bruntt et al. (2008), Catanzaro et al. (2011), Fossati et al. (2011), Tkachenko et al. (2012), Bradley et al. (2015), and Van Reeth et al. (2015) and some hybrid γ Dor–δ Sct stars from Catanzaro et al. (2011) and Tkachenko et al. (2012).
