\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}}
