Notes. Presented are mass M, radius R, luminosity L, effective temperature T_eff, surface gravity log g, metallicity [Fe/H], microturbulent velocity ξ, rotational broadening υ sin i, macroturbulent velocity ζ, and the V-band extinction A_V used to determine the parameters. The values for reddening E(B – V) given by Holanda et al. (2022) and Carlberg et al. (2016) were converted assuming A_V = 3.1 E(B – V). (1) Stock et al.
