The fraction of Titania’s water–ice inherited from the molecular cloud, fcloud, as a function of the deuterium abundance of water in the cloud, (D/H)cloud. The range of deuterium abundances reflects the range of values in models and observations, as described in L. Yang et al. (2013). Most of Titania’s ice comes from reprocessed ice in the inner protoplanetary disk that was radially transported into the outer parts of the disk.
