The extended Poincare map in this paper needs twosurfaces of sections transversal to the flow in phase space,i.e.,relates the crossing of a plane containing one of the collinear libration points back to the periapsis passage.Meanwhile,the map is calculated numerically using the Total-Variation-Diminishing Runge-Kutta integration method to get a good description of the Poincare sections.
