Polar diagrams of the intrinsic beam patterns of 4U 0115+63 for the observations B (maximum) and E (end of decay) for the softest band and the hard band above  ~20 keV. Up (0°) is the direction straight up from the magnetic pole, 90° and 270° are the directions tangential to the neutron star surface at the magnetic pole. These beam patterns correspond to the asymptotic beam patterns of the minus solution shown in Fig. 9.
