T_eff-log g diagram for our stellar sample. The green, blue, and red lines are the PARSEC isochrones at ~500 Myr, ~2 Gyr, and ~12.5 Gyr. Dotted, solid, and dashed lines represent three different values of metallicities, as labeled in the bottom left corner. The inset represents the histogram distribution in [Fe/H] of our targets. The star symbols are colored from dark to light and represent the most metal-rich to most metal-poor stars according to four bins: [Fe/H] ≥ +0.24 dex, −0.12 < [Fe/H] ≤ +0.24 dex, −0.15 < [Fe/H] ≤ −0.02 dex, and [Fe/H] ≤ −0.15 dex.
