Dimensionless emissivity for the linear polarization e₁, J₁ = 1 − R₁, as a function of photon energy E for condensed Fe surface at different magnetic field strengths and geometric settings. Top panel: magnetic field B = 10¹³ G is normal to the surface, and angles of radiation incidence are θ_k = 0, π/6, π/4, and π/3. Bottom panel: B = 10^13.5 G, magnetic field lines and the photon beam are both inclined at θ_B = θ_k = π/4, and the azimuthal angle takes values ϕ = 0, π/4, and π/2. Solid lines show the numerical results, and dashed lines demonstrate the fit.
