Notes. From top to bottom, the parameters are initial mass, metallicity, exponential CBM parameter, envelope mixing at the CBM interface, and central hydrogen content. The columns list the best stellar models from different grids: their best grid ψ1 which has constant envelope mixing, and grids ψ2 and ψ6 which have the same prescription for envelope mixing as employed in this work. The average and errors listed are the updated values from Pedersen (2022b) for their indistinguishable grids. The rotation frequency is from Pedersen (2022a).
