Format

The two data frames contain 6 variables:

mass

the RGB mass of the model.

z

the initial metallicity of the model.

y

the initial helium abundance of the model.

ml

the mixing-length of the model.

mix

the alpha-enhanchment of the model. It is coded mix=AS09a0 for [alpha/Fe] = 0.0 and mix=AS09a3 for [alpha/Fe] = 0.3.

masshb

the HB mass of the model. The dataset masshbgrid contains multiple values for masshb for each single RGB progenitor mass.
