Table 7: Summary of the line identifications for Fe X (see the Appendix for details). The columns indicate: 1) the indexes corresponding to Table 3; 2) the relative intensity (at 10⁸ cm^-3), scaled to the brightest line; 3) the wavelengths calculated from our best energies $E_{\rm best}$ ; 4) observed solar wavelengths $\lambda _{\rm solar}$ (unless specified otherwise values are from Behring et al. 1976); some blends are indicated (bl = blend; bl-mr = blend in medium-resolution spectra; bl-w = blend with a weak line); lines with no or a tentative identification have a question mark; 5 and 6) previous identifications consistent or not with ours (with observed wavelengths in Å; note that observed and calculated wavelengths in the cited literature can differ from the values reported here).
