$^a$ Damping constants computed following Barklem et~al. (\cite{Barklem98}, \cite{Barklem00});
$^{aa}$ damping constants computed as in $^a$, decreased by a factor 1.5~($C_6$/1.5).
Other $C_6$ values are van der Waals classical ones, as described in
Zoccali et~al. (\cite{Zoccali04}).
Column 5 reports the log~$gf$ used in Zoccali et~al. (\cite{Zoccali04}), adopted from
$^1$ NIST/VALD; $^2$ Barbuy et~al. (1999); $^3$ McWilliam \& Rich (\cite{McWilliam94}); $^4$ Bensby et~al. (2004),
whereas Col.~6 gives the values derived in this work from a fit to the solar spectrum;
$^*$ for TiII 6491.58 ${\rm \AA}$ line, the NIST log~$gf$~= $-2.10$ is different from the VALD
value of log~$gf$~=~$-1.793$.
