Image Details
Caption: Figure 13.
Identical to parameters of Figure 12 except splitting attenuation is applied to both polarization modes rather than only ⊥ → ∥∥. High-energy flux and (late-time) polarization are strongly modified, as only a narrow annulus at higher energy is capable of escape (e.g., 108 keV panel). The overall burst spectrum is also modified, with a steeper splitting-induced cutoff.
