Final (at 10 Myr) planetesimal column density as a function of disk radius for the first sample (gray values in Table 1). The fiducialvalues for this set of simulations are shown in the header of the plot. In each panel, the simulation with those parameters is shown as dashed gray line, and the solid lines with colors show simulation results where only one parameter of the set was changed. The gray areas represent the constraints that we described in Sect. 2, where the mass in the given region was translated into a column density, assuming a planetesimal profile ∝ r^−2.25 (see Eq. (37) of Lenz et al. 2019). For the outermost region, we also overplotted a box ∝ r⁻⁸.
