Upper-left panel: adopted temperatures derived from the excitation potential equilibrium (T_effspec) as a function of photometric temperatures obtained from colours (V − K). Upper-right panel: adopted gravities from ionization equilibrium (log g_adopted) as a function of gravities obtained from the estimated mass (log g_photometry), radius, and adopting a distance modulus of (m − M)_V = 13.60 (Harris 1996). Lower-left panel: adopted gravities versus the calibrated T_eff-logg relation from Kučinskas et al. (2006). The dashed line in these three panels indicates perfect agreement. The mean difference between the adopted values and the comparison ones has been quoted in each panel (as Δ(comparison-adopted)). Lower-right panel: distances Δ(log g) of each point in the upper panel, in the - plane, from the line of perfect agreement, as a function of the adopted T_eff.
