def METHOD_NAME(self, throats=None):
    r"""
    Finds the indicies of the Voronoi nodes that define the facet or
    ridge between the Delaunay nodes connected by the given throat.
    Parameters
    ----------
    throats : array_like
        The throats whose facets are sought.  The given throats should be
        from the 'delaunay' network. If no throats are specified, all
        'delaunay' throats are assumed.
    Notes
    -----
    The method is not well optimized as it scans through each given throat
    inside a for-loop, so it could be slow for large networks.
