Relative abundance of gas-phase water derived from observations of p-HO by (Persson et al. 2012) and continuum (for estimating the H2 abundance) for different methods of estimating the disk gas mass. The values of the mass by Jørgensen et al. (2009) used by Persson et al. (2012) are drawn as red open circles. The size of the symbols reflects the uncertainty; for IRAS 4A-SE the values are upper-limits.
