Fig. 1

Top left to bottom right panels: phase-plots obtained for the PC, SG, OG/OPC, and radio (core plus cone) models respectively, with a magnetic field strength of BG = 108 Tesla and spin period of 30 ms for the PC and radio cases, and gap widths of 0.04 and 0.01 for the SG and OG/OPC cases, respectively. All the plots are given for an obliquity α = 45°. The emission flux increases from black to red.
