Comparison plots of photometric (from Brown et al. 2018) and spectroscopic (from this paper) determinations of the effective temperatures and the stellar radii. The black diagonal line represents the 1:1 correlation and the red line represents the linear fit of the data. At the bottom of each figure, the residuals compared to the 1:1 correlation are shown, with their 1 and 2σ dispersions represented by the shaded regions. Left: effective temperatures seem to show a linear trend, but this is not significant compared to the dispersion of the date of ~ 110 K, inside which more than 85% of the data is located. Right: radii are in good agreement but show an apparent trend and increasing dispersion for masses above than ~ 15 M_⊙.
