Flux and polarization spectra for different observer viewing angles in the full model. The parameters are as follows: B_p = 5 × 10¹³ G, R = 10 km, kT_e = 10 keV, kT_s = 0.6 keV, ξ_τ = 0.2, β₀ = 0.5, and a hot spot at (θ_s, ϕ_s) = (90°, 37°). Results are shown for viewing angles θ = 37°, 68°, 112°, and 143°.
