Notes. All transitions are used for the TARDIS modelling, while we tested the Y+ P Cygni framework using only the transitions listed here with λ > 700 nm and all the transitions in this table. Vacuum wavelengths (λ), energy levels (E), and oscillator strengths (log gf) for the Y+ 4d5p to 4d2 lines are from Biémont et al. (2011).
