// This was an old definition of the criterion "the hyp is within
// max_distance_ area from the ref". The positive thing about the
// definition is, that it allows binary search through the collection
//        ret &= fabs(left.tbeg - right.tbeg) <= max_distance_;
//        ret &= fabs(left.tend - right.tend) <= max_distance_;

// This is the newer definition -- should be equivalent to what F4DE uses
    ret &= fabs(center_left - center_right) <= max_distance_;
