\caption{Line parameters used for the calculation of line profiles. $\zeta$ is a term multiplying the Uns\"{o}ld value of~$\gamma$ in the Lorentz part of the absorption profile, while~$\xi$ is the usual microturbulence term. The values of $\lg~(gf)$, $\zeta$ and~$\xi$ are chosen to optimize the comparison with atlas data.\label{tablinedata}}
