Top panel: masses of the compact disks in Lupus (R < 30 au). These masses were obtained through the RADMC-3D model grid for τ < 5. The dashed black line indicates where the RADMC-3D dust mass equals the optically thin dust mass calculation (see Eq. 10). Top-right panel: Kernel density estimation of the disk dust masses. Bottom panel: cumulative distribution functions (CDFs) of all the disk masses in Lupus, using two approaches: in teal, all masses are estimated with the optically thin approximation based on flux values (Eq. (10)), and in pink, we substitute the masses with values derived from our model grid where available.
