Caption: Figure 1.
Collision velocities at ﹩5\;\mathrm{au}﹩ and ﹩\alpha ={10}^{-3}﹩ at the midplane (top panel) and at ﹩z/{h}_{{\rm{g}}}=2﹩ (bottom panel). Brownian motion, turbulence, and differential settling are also included. The red contours mark vfrag (solid) and ﹩{v}_{\mathrm{frag}}-\delta {v}_{\mathrm{frag}}﹩ (dashed).
