Total planetesimal mass as a function of time for the first sample (gray values in Table 1). The fiducial values for this set of simulations are shown in the header of the plot. In each panel, the simulation with those parameters is shown as the dashed gray line, and the solid lines with colors show simulation results where only one parameter of the set was changed. The gray area shows values more massive than the solids of the MMSN (Weidenschilling 1977a; Hayashi 1981).
