\begin{table}%t4 %\centering \par \caption{Atomic data of \FeI\ lines used in the analysis of the reference stars. Column~1 gives the multiplet number, Col.~2 the wavelength in~\AA, Col.~3 the lower excitation energy, Col.~4 the differential log~$gf$ value with respect to log~$\varepsilon$(Fe)$_\odot$~=~7.51, Col.~5 the employed log~$C_6$ value. The products log~$gf\varepsilon_\odot$ that the log~$gf$ values presented here imply differ slightly from those presented in Paper~II. This is because a global minimization was performed in Paper~II to determine the log~$C_6$ values, whereas lines were fitted individually here on the basis of the minimization procedure. A radial-tangential approximation to macroturbulence (Gray \cite{Gray77}) was used for the analysis of the Sun, a Gaussian otherwise. The equivalent widths (in m\AA) in Cols.~6--10 are of low quality, but only enter the analysis in the derivation of the microturbulence. We discourage from using these values for abundance analyses.\label{FeIdata}} { \begin{tabular}{rccrcrrrrr} \hline\hline Mult. & $\lambda$ & $E_{\rm low}$ & log~$gf_{\rm diff}$ & log~$C_6$ & Procyon &
