The predicted gas-phase atomic H abundance with respect to hydrogen nuclei at AV = AV,crit as a function of Z and ζ/nH. Solid lines and dashed lines represent with (Equation (A4)) and without (Equation (A2)) the atomic H release to the gas phase upon water ice photodissociation. The parameter α is set to 0.95.
