Notes. For each line we give the wavelength (air), the log gf value, the lower excitation energy (χl), the absolute abundance (log ϵ(X)), and the references for the oscillator strengths: H91 = Hibbert et al. (1991), BZ92 = Biemont & Zeippen (1992), H17 = Haris & Kramida (2017), W96 = Wiese et al. (1996), H93 = Hibbert et al. (1993), and NS84 = Nussbaumer & Storey (1984).
