Distribution of masses of exoplanetary systems obtained from the exoplanet.eu catalog (Schneider et al. 2011), for the planets around main sequence stars with the measured masses. Shaded areas mark the range of our best estimation of the dust disk masses in Perseus: Class 0 (red) and Class I (blue) calculated from the VLA fluxes with the opacity value of κ_{9 mm} = 0.28 cm² g⁻¹. Medians of the distributions, 158 and 52 M_⊕, for Class 0 and I, respectively, are indicated with the dashed lines. The median mass of the Class II disks in Lupus, 3 M_⊕ (Ansdell et al. 2016) is showed in yellow. The masses of the solids in exoplanetary systems are plotted against the stellar mass of the host star. All planets with available information on the mass are included in this plot without introducing the 0.3 M_J threshold.
