Notes. The lines are displayed in decreasing order of intensity (photons) Int = NjAji/Ne relative to the strongest EUV line. The intensities were calculated at log Te [K] = 6.15. Columns 3, 4, 5 show the relative intensities calculated at log Ne [cm-3] = 8 with the DW4, RM4, and RM4+DW6 ion models. Column 6 shows the values at log Ne [cm-3] = 12 from the RM4 ion model. Columns 7, 8 show the gf and A values calculated in this work. The values in brackets are those calculated by Bhatia et al. (2002). The next column shows the experimental wavelengths. Values indicated with ∗ are from Del Zanna (2012), the others are from Fawcett et al. (1972). The last column shows the wavelengths corresponding to the target energies. Values in parenthesis give the corresponding wavelength difference with the experimental ones.
