Notes. The first column lists the indices of the levels, as from Table 2. The second the spectroscopic notation. Columns 3 and 4 show the intensities (photons) of the strongest lines, relative to the resonance transition, calculated at log Ne [cm-3] = 9 and log Te [K] = 6.1, using the present and the CHIANTI ion models. The CHIANTI model uses the Aggarwal & Keenan (2007) collision strengths for the first 17 levels and for the rest those of Bhatia & Landi (2011). Column 5 lists the weighted oscillator strength gf and Col. 6 the A-values from our calculation. Column 7 lists the Bhatia & Landi (2011) A-values as given in the CHIANTI v.7.1 database. TN is a tentative new identification, R a revised wavelength (compared to NIST), bl a blend. All wavelengths are in vacuum.
