Table 6: Summary of the line identifications for Fe XXIII The columns indicate: 1) the indices corresponding to Tables 2; 2,3) the relative intensities (in photons, scaled to the 1-15 10.980 Å line and calculated at log ) typical of astrophysical and laser plasmas (10¹², 10¹⁹ cm^-3); 4) the wavelengths calculated from our best energies ; 5) observed wavelengths ; 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; 6,7) 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).

The final column indicates weather the lines have only been observed in high-density plasmas (H).
