Intensity of the diffracted wave in the O′ plane for different initial waves k_ρφ. Panel a: A coaxial wave ρ = 0 is shown; panel b: a moderately tilted wave with ρ = 10.24′ is shown; and panel c: a highly tilted wave with ρ = 16′ is represented. panel d: The intensity is integrated for all the points along the solar radius. The dS = ρ dρ dφ factor was taken into account during integration, thus the color table is different. The value φ = 35° was used in the latter three cases.
