Notes. The lines are displayed in decreasing order of intensity (photons) Int = NjAji/Ne relative to the strongest 1–27 line (in the EUV). The intensities were calculated at log Te [K] = 6.2. Columns 3–5 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 last two columns show the wavelengths corresponding to the experimental and target energies. Values in parenthesis list the corresponding wavelength difference.
