The top to bottom panels illustrate the γ-ray emission pattern obtained for a young (left) and old (right) pulsar, respectively for the PC, SG, OG/OPC, and radio (core plus cone) models. For the PC and Radio models, the time evolution is obtained for B = 10⁸ T and period increasing from 30 to 1000 ms. In the SG and OG/OPC models, the time evolution is obtained for a gap width w_SG increasing from 0.04 to 0.5 and w_OG/OPC increasing from 0.01 to 0.4 respectively. All the plots are given for an obliquity α = 45°.
