Table 1: 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 Brooks et al. (1999). $T_{\rm p}$ 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 Edlén (1983a,1984,1985c,b,a,1983b), F for Fawcett (1975), K for Kelly (1987), N for Martin et al. (1995), and O for Wiese (1985), respectively.
