  \tablefoot{For each spectrum, the first column is the height h, in the units employed in Fig.~\ref{fig1}, the second column is the central wavelength $\lambda$ in~\AA~ and the third is the standard deviation $\sigma$ of each Gaussian profile, also in~\AA. The numbers in parentheses are the fitted errors.}
