Notes. In these analyses, we assumed the classical von Zeipel model with β = 0.25. Teff (PNRC), log g (PNRC), and v sin i (PNRC) are, respectively, the surface temperature, gravity, and the projected rotation velocity of the PNRC, which are the parameters these stars would present in the absence of geometrical deformation and (T, log g) colatitudinal dependence. Apparent parameters are those calculated with classical model atmospheres.
