Steady-state abundance for H₂ and the different H₂O carriers for the standard disk model (H₂O# means physisorbed water). The white contours correspond to the gas temperature in the upper right panel. χ is the strength of the UV field (χ = 1 corresponds to the average local interstellar medium. The water ice location analytical model of Min et al. (2016) is shown (white dashed line). In the same panel the alternative formula from Antonellini et al. (2016) is also displayed (yellow dashed line).
