Notes. The table includes all objects for which gas extent could be estimated following the methodology described in Sects. 3.1 and 3.1.2. Distances of the sources are estimated as the inverse of the parallax (from Gaia DR2 Gaia Collaboration 2018); the tabulated distance of objects with uncertain parallax is the mean distance of the Lupus clouds (158.5 pc). Dust mass was obtained assuming optically thin emission of the ALMA Band 7 continuum observations, with a dust optical depth of κ890 μm = 2 cm2 g−1 and an average dust temperature of Tdust = 20 K. (*)The modeled emission of Sz 83 based on our methodology includes the Keplerian emission, non-Keplerian extended emission, and part of the spiral structure as reported in Huang et al. (2020). Therefore, the true CO size of the Sz 83 disk might differ from the tabulated value.
