Case A or Case B? The effective recombination coefficient in gas clouds of arbitrary optical thickness

In calculations of the ionization state, one is often forced to choose between the Case A recombination coefficient \(\alpha_{\rm A}\) (sum over recombinations to all hydrogen states) or the Case B recombination coefficient \(\alpha_{\rm B}\) (sum over all hydrogen states except the ground state). I...
