Photon flux (top row) and DOP (bottom row) for upward primary (orange), albedo (blue) and total (green) components across the entire source for the Δν = 4.0 (1st column), the Δν = 0.5 (2nd column) and the Δν = 0.1 (last column) created photon distributions respectively, at the peak albedo energies of 20–50 keV, for different locations on the solar disk from the centre (μ = 1.0) to the limb (μ = 0.0). Note here that a negative DOP denotes that the direction of polarization Ψ across the source is parallel to the radial direction. The DOP for Δν = 4.0 photon distribution (near isotropic distribution) shows  ~  the same result as Bai & Ramaty (1978), as expected.
