Table 1

Conditions for the streaming instability are satisfied relative to the total area of the disk (middle column).

Streaming instability condition	Area(SI)	M_d,gr(SI)
Yang et al. (2017), Eqs. (26), (27), (28)	0.0268%	87.9%
Li & Youdin (2021), Eqs. (29), (28)	0.0269%	87.91%
Li & Youdin (2021), Eq. (30)	0.0288%	88.21%

Notes. Right column shows the total mass of grown dust contained within the disk region prone to the streaming instability relative to the total mass of grown dust in the disk. All data refer to the fiducial model.
