Caption: Figure 9.

The accessible mass limits using the contrast curve from Figure 6 are shown in this figure. The light cyan curve utilizes the cloudy models from D. Saumon & M. S. Marley (2008), the dark cyan curve utilizes the equilibrium case of ATMO 2020 (M. W. Phillips et al. 2020), and the black curve employs COND 2003 (I. Baraffe et al. 2003). The lower limit on the x-axis is 0.5λ/D, which is approximately the practical achievable IWA with AMI. The dashed gray line shows the conventional diffraction limit below which the contrast curve begins to grow steeply for accessible mass limits.
