Upper left panel: variation of the scaled magnetic field strength (B) 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). Upper right panel: corresponding variation of the scaled magnetic field strength along the pair plasma (e⁻ − e⁺) jet sightline indicated by the red dot in the lower right panel of Fig. 4. Middle left panel: variation of the scaled electron number density (n_e) along the normal plasma jet sightline. Middle right panel: corresponding variation of the scaled electron number density along the pair plasma jet sightline. Lower left panel: variation of the minimum electron Lorentz factor (γ_min) along the normal plasma jet sightline. Lower right panel: corresponding variation of the minimum electron Lorentz factor along the pair plasma jet sightline. These panels highlight the physical scaling (i.e., Sect. 2) that we have applied to our dimensionless PIC grid values.
