Corner plot for synthetic data. The orange posteriors show the synthetic optically thin case, calculated with Ṁ_p = 10⁻⁹ M_Jup yr⁻¹ and α = 10⁻³. The outcome illustrates the degeneracy between Ṁ_p and α inherent to the parametric CPD model of Zhu et al. (2018). The grey posteriors show the synthetic optically thick case, calculated with Ṁ_p = 10⁻⁵ M_Jupyr⁻¹ (and the same α = 10⁻³). Both synthetic SEDs were obtained using only the dust component of the CPD model following Zhu et al. (2018), with errors set to 10% of the flux.
