Contopoulos & Papayannopoulos (1980, A&A, 92,33) used this potential in the study of orbits in barred galaxies. Note that their ``bar'' is oriented along the Y-axis, and an axis ratio is not well defined. The potential used is given by adding an axisymmetric component to a m=2 fourier component: where is the Isochrone potential with unit scalelength and mass, and the Barbanis & Woltjer (1965) potential: and
