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.

Member Function Documentation

int siscone_spherical::CSphstable_cones::get_stable_cones ( double  _radius)

compute stable cones.

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

Parameters:
_radiusradius of the cones
Returns:
The number of stable cones found is returned
