Upper left panel: variations of the Stokes parameters for the normal plasma (e⁻ − p⁺) jet along the sightline indicated by the red dot in the lower left panel of Fig. 4. The radiative transfer progresses from left to right: starting on the far side of the jet relative to the observer (cell 0) and then advancing through the jet plasma toward the near side of the jet (cell 240). The inset shows the variation in the fractional circular polarization along the same sightline. Upper right panel: corresponding ray properties along the pair plasma (e⁻ − e⁺) jet sightline indicated by the red dot in the lower right panel of Fig. 4. Lower left panel: variations of the Faraday rotation (τ_F) and conversion (τ_C) depths along the normal plasma jet sightline. Lower right panel: corresponding Faraday depths along the pair plasma jet sightline.
