Left panel: variation of the electron Larmor radii (r_gyro) within 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 red dashed line in each panel demarcates the scaled PIC grid cell size (Δl_scale). Right panel: corresponding variation of the pair plasma (e⁻ − e⁺) jet Larmor radii along the sightline indicated by the red dot in the lower right panel of Fig. 4.
