Fig. 6


Integrated line flux of HD 1–0 as a function of the gas-to-dust mass ratio for fixed gas mass (Mgas = 2.3 × 10-2M). The fluxes are normalized to the median flux of the Mdisk = 2.3 × 10-2M mass bin. The triangular marker denotes the value of Δgd in the fiducial model of the TW Hya disk (Kama et al. 2016b; cf. Table 2).
