Asymptotic abundance ratios for a streamline launched at R₀ = 0.15 au in the disk as a function of the “observed” mass-flux Ṁ_obs (see Eq. (21)) for dust-free models (cyan) and dust-poor models with Q∕Q_ref = 10⁻³ (blue), 10⁻² (green), and 0.1 (red) as well as for different values of Ṁ_w = 10⁻⁷ (straight crosses), 5 × 10⁻⁷ (crosses), 10⁻⁶ (triangles), 2 × 10⁻⁶ (squares), and 5 × 10⁻⁶ (circles) M_⊙ yr⁻¹. All other parameters are kept constant to the values given in the footnote of Table 3. In particular T_K = 1000 K.
