Table 1

Assumed parameters for the parent belt.

Id.	M_b [M_⊕]	Δa_b [au]	t_settle [Myr]	Description
n	0.09	10	20	reference
w	0.09	20	20	Wide
m2	0.28	10	6.4	High mass
m3	1.4	10	1.3	Very high mass

Notes. M_b is the total belt mass in objects with radii s < 500 m, ∆a_b the spread in orbital semimajor axes, and t_settle the time during which the size distribution is allowed to settle to a collisional equilibrium before collisions and perturbations were modeled jointly. See text for details.
