Fig. 5


Periodic variable polarization for two equatorial CIRs. The format is the same as in Fig. 4 with light curves to the left, q-u plane variations to the right, a viewing perspective of i = 30° at the top, and i = 60° along the bottom. The two CIRs are shifted from each other by an angle Δϕ of (black), 30° (red), 60° (green), 90° (dark blue), 120° (light blue), 150° (magenta), and 180° (orange).
