Notes. Models: M05R: single-star model with rotation from Meynet & Maeder (2005); M05NR: single-star model without rotation from Meynet & Maeder (2005); E08S: single-star model from Eldridge et al. (2008); E08B: binary model from Eldridge et al. (2008); X15H: hybrid single+binary population models from Xiao & Eldridge (2015); S20B: binary models from Stanway et al. (2020). Models that show good agreement with the observed (Ib+Ic)/II ratios across all three samples.
