\caption{Lines used for the integral inversion and for evaluating
           the elemental abundances. $\lambda^{\rm ad}$ is our
           preferred laboratory wavelength and $\lambda^{\rm cor}$ the
           "corrected'' observed wavelength in
           \citet{Brooks_etal:99}.  $T_{\rm p}$ is the peak
           temperature of line formation. Since one line per ion at
           most is used in the integral inversion, we indicate with
           "i'' the lines used in the integral inversion and~"f''
           the lines compared with observations in the forward sense,
           i.e. by comparing the intensities predicted using the DEM
           with the observed intensities. The source for the adopted
           wavelengthis is denoted by~E for \citet{Edlen:83a,Edlen:83b,Edlen:84,Edlen:85a,Edlen:85b,Edlen:85c}, F
           for \citet{Fawcett:75}, K for \citet{Kelly:87}, N for
           \citet{Martin_etal:95}, and O for \citet{ORNL:85},
           respectively.}
