DEF

Slight departure from the spherical form.

CONT

In contrast to off-lattice DLA clusters, the overall shape of cluster-cluster aggregates is not spherical. Instead, these aggregates can be characterized by a well-defined asphericity which becomes more pronounced as the clusters become larger. The overall shape cannot be spherical since joining two spherical clusters would immediately destroy the symmetry.
