Abstract

We list vacuum wavelengths, energy levels, statistical weights, transition probabilities, and oscillator strengths for permitted resonance spectral lines of all ions of 18 astrophysically important elements (H through Si, S, Ar, Ca, Fe). Using a compilation of experimental energy levels, we derived accurate wavelengths for 5599 lines of 1828 ground-term multiplets which have gf-values calculated in the Opacity Project. We recalculated the Opacity Project multiplet gf-values to oscillator strengths and transition probabilities of individual lines. For completeness, we added 372 resonance lines of Ne I, Ar I, Fe I, and Fe II ions which are not covered by the Opacity Project. Intercombination and forbidden lines are not included in the present compilation.
