The codes below adds equilibrium ionization to a battle-tested stellar equation of state that had assumed full ionization. The first version implements a simple two-level hydrogen atom like model, while the second version implements all stages of ionization for elements between hydrogen and zinc.

Please cite the relevant references if you publish a piece of work that use these codes, pieces of these codes, or modified versions of them. If you're nice, offer co-authorship of the publication. At best, you'll love these programs so much that you'll send great wads of cash to me.
