Detailed Description

Computes the list of stable comes from a particle list.

This class does the first fundamental task of te cone algorithm: it is used to compute the list of stable cones given a list of particles.

)

compute stable cones.

This function really does the job i.e. computes the list of stable cones (in a seedless way)

Parameters

_radius

radius of the cones

Returns

The number of stable cones found is returned
