Same as Fig. 6 but for PDS 70 b. The purple circles, squares, and diamonds respectively represent the planet properties of the three cases; Case A ($M_{\mathrm{p}\mathrm{l}}=10M_{\mathrm{J}}\text{ and }{\dot{M}}_{\mathrm{g},\mathrm{p}\mathrm{l}}=2\times {10}^{-7}{M}_{\mathrm{J}}{\mathrm{y}\mathrm{r}}^{-1}$; same with the plausible case of PDS 70 c), Case B (M_pl = 12 M_J and ${\dot{M}}_{\mathrm{g},\mathrm{p}\mathrm{l}}=4\times {10}^{-8}{M}_{\mathrm{J}}{\mathrm{y}\mathrm{r}}^{-1}$), and Case C (M_pl = 5 M_J and ${\dot{M}}_{\mathrm{g},\mathrm{p}\mathrm{l}}=3\times {10}^{-9}{M}_{\mathrm{J}}{\mathrm{y}\mathrm{r}}^{-1}$). (Left) The red curves represent the signal to noise ratios (1σ = 15.7 μJy) if the dust emission were detected in the observation by Benisty et al. (2021). The black curves and lines represent the previous estimates of the properties listed in Table 2. The light grey curves and lines also represent the previous estimates, but they are from different works from those of PDS 70 c. (Right) The red, brown, green, and orange curves represent the 3σ = 47.1 μJy noise levels with (α, x) = (10⁻⁴, 0.01), (10⁻⁵, 0.01), (10⁻³, 0.01), and (10⁻⁴, 0.001), respectively.
