SAHA-S version 7. Introduction
Tables are provided for four sets of relative abundances of heavy elements. Two of them correspond to widely used Z mixtures AGSS09 and GN93.The third set includes only C, N, O and Ne, and abundances of these elements are taken exactly as in OPAL EOS tables. Fourth set is for the composition from Magg (2022). The mass fractions of heavy elements in SAHA-S7 are listed in the table:
