Projected cosmic-ray density as a function of the distance from the GC, computed using a 3D reconstruction of the gas distribution in the region. The underlining profile is assumed to have a ρ_CR ∝ r⁻¹ shape. Blue line shows the true projection, whereas the orange one depicts the estimate. Dashed and dotted grey lines represent the exact solutions for the α = {1, 2} cases respectively, arbitrarily scaled to fit the image. The calculation was performed for the ±10 pc Galactic latitude slice along the Galactic plane.
