[Cl/Fe] | This form lets the user specify a chemical mixture in bracket notation and then calculates mass fractions X, Y, and Z according to three published standard mixtures. | |
[Ar/Fe] | Helium mass fraction (Y) stays at the standard solar value unless the user changes it to something nonzero. | |
[K/Fe] | Remember, X + Y + Z = 1. | |
[Ca/Fe] | Disclaimer: We didn't program much error-checking, so be wary of garbage in - garbage out problems. | |
