testComposition | R Documentation |
Check that the given chemical composition (Z, Y, [alpha/Fe]) and the mixing-length value exist in the stellar database.
testComposition(Z, Y, ML, AFE)
Z |
the initial metallicity of the model. |
Y |
the initial helium abundance of the model. |
ML |
the mixing-length of the model. |
AFE |
the alpha-enhanchment of the model. Allowed values are |
The function returns TRUE
if the combination of the inputs
exists in the database.
