Notes. The lines are grouped in different transition arrays, and are displayed in decreasing order of intensity. Columns 3–5 show the relative line intensities (photons) Int = NjAji/Ne calculated at log Ne [cm-3] = 8 and log Te [K] = 6.2 with the RM4, DM05, and RM4+DW6 ion models (see text). Intensities are normalised to the intensity of the brightest line. Columns 6, 7 show the gf and A values calculated in this work. The last column shows the wavelengths corresponding to the experimental energies.
