Caption: Figure 6.
The T90-averaged spectra in different models. Colors represent different models, as in Figure 5. The solid (θv = 10°), dashed (θv = 20°), and dashed–dotted (θv = 45°) lines represent different viewing angles. The black dashed line is a power-law spectrum with a photon index of 2.5.
