Set-up for the nominal case runs.

PLANET
Planet/star mass	^∗μ = 2 × 10^-3
eccentricity
semi-major axis	a_p = 75 AU
PARENT BODY RUN
Number of test particles	N_PB = 2 × 10⁵
Initial radial extent	30 < r < 130 AU (embedded planet case)
	45 < r < 75 AU (inner-disc/outer-planet case)
Initial eccentricity	0 ≤ e ≤ 0.01
Initial surface density	Σ ∝ r^-1
COLLISIONAL RUNS
Average optical depth	^*τ = 2 × 10^-3
Number of test particles	N_num = 2 × 10⁵
Size range^a	s_cut ≤ s ≤ 40s_cut
Size distribution at t = 0^b	dN(s) ∝ s^-3.5ds

Notes. Parameters denoted by a * are explored as free parameters.

^(a)

s_cut is the radiation pressure blow-out size.

^(b)

When released from the parent body population.
