Total planetesimal masses for the fiducial model (solid black) and parameter study models. The latter include the models with vfrag = 3.0 m s−1 (solid red), ﹩{\xi }_{{\rm{d2g}}}^{{\rm{init}}}=2\times 1{0}^{-4}﹩ (solid blue), with the streaming instability criteria from R. Li & A. N. Youdin (2021) (dashed green), MRI with solar metallicity excitation criteria (cyan), and gravitoturbulence (pink).
