Stellar parameters for all stars analyzed vs. scaling relations. Top: effective temperature T_eff vs. surface gravity ﹩\mathrm{log}g﹩ compared to MIST isochrones (J. Choi et al. 2016) of three different metallicities ([Fe/H] = −2.0, −2.5, −3.0). We generally recover slightly higher or lower T_eff and ﹩\mathrm{log}g﹩ values than expected from the isochrones. Bottom: surface gravity ﹩\mathrm{log}g﹩ vs. microturbulence ν_t compared to the empirical scaling relations given in P. S. Barklem et al. (2005; B05), A. F. Marino et al. (2008; M08), and E. N. Kirby et al. (2009; K09).
