Table 1:

Nominal case set up.
Radial extent^a	10<r<100 AU
Radial surface density profile	$\Sigma \propto r^{-0.5}$
Number of test particles N	$5\times 10^{4}$
Size range^b	$\beta(s_{\max})=0.025<\beta(s)<\beta(s_{\min})=0.4$
Normal rebound coef. $\epsilon_{\rm N}$	-0.3
Transverse rebound coef. $\epsilon_{\rm T}$	1
Size distribution	${\rm d}N(s) \propto s^{-3.5}{\rm d}s$
Inflated radius (in AU)	$s_{\rm num}=10^{-4} \times (s/s_{\min})$
Initial dynamical excitation^c	$\langle e_{\rm dyn} \rangle = \langle i\rangle = 0$

^a Initial location of particles' periastron.
^b As parameterized by $\beta \propto 1/s$ .
^c The value for $\langle e_{\rm dyn} \rangle$ is that of hypothetical large particles with $\beta=0$ , not taking into account the eccentricity component due to radiation pressure.
