For $\Lambda(T_{\rm eff})$ and $T_{\rm eff}$ the temperature $T_{\rm eff}(\gamma )$ is simply the effective temperature written in the first column of the table.
Parameters $\delta^*_{\rm UV}$ and $\delta^*_{\rm IR}$ are values of $\delta_{\rm UV}$ and $\delta_{\rm IR}$ calculated with $T_{\rm eff}(\gamma )$ and fluxes $F_{\lambda}[T_{\rm eff}(\gamma),\log g]$ , which do not undergo the transformation given by Eq. (6). To calculate them we have used $\lambda_a=1380$ Å and $\lambda_b=11~084$ Å. Note that $T^f_{\rm eff}=$ $T_{\rm eff}(\gamma=1)$ .
