Integrated monomer residence time as a function of home aggregate size for different fragmentation velocities (solid coloured lines). The solid black lines on the left and right represent the minimum and maximum grain size occurring throughout the entire vFrag5 background disk model. The dashed lines all denote the same background dust mass distribution as a function of size, ρ_d(a) at r = 10 AU and z = 0, shifted vertically for comparison with the integrated monomer residence time.
