Cumulative distributions of the gas masses from Figs. 7 and 10 obtained from our models (dark blue) and obtained from the C¹⁸O flux (green), and dust masses ×100 (orange) from Stapper et al. (2022). The corresponding probability distributions are shown in the middle panel, obtained by fitting a lognormal distribution to the cumulative distributions. The faint lines indicate the possible range in fits. Sampling from the gas and dust distributions a distribution of possible gas-to-dust mass ratios can be made, as shown in the right most panel.
