Goodness of fit of our models at T_{p, int} = 200 K and nominal irradiation as a function of metallicity and K_zz, compared tothe data from Benneke et al. (2019; left) and Tsiaras et al. (2019; right). The white colour corresponds to the value of χ² = 21.36, indicating a fit at the 1σ confidence level. The best fit against Benneke et al. (2019) data (χ² = 20.64) is located at (Z/H)_⊙ = 125 and K_zz = 10¹⁰ cm² s⁻¹. The best fit against Tsiaras et al. (2019) data (χ² = 16.56) is located at (Z/H)_⊙ = 200 and K_zz = 10⁵ cm² s⁻¹.
