(a) Angles between vectors s, s′ and jd (r). The vector s defines the z′. The vectors s and jd (r) define the (y′, z′) plane. (b) Contributions of the neglected integral term, PFC term and diffuse reflectance term to the reflectance. Black line—radially dependent diffuse reflectance Rd (ρ), blue line—contribution of the PFC term Rp (ρ), red line—contribution of the neglected integral term ΔRp (ρ). The contribution of the neglected integral term, ΔRp (ρ), is less than 4% of Rp (ρ) for 
. The contribution of ΔRp (ρ) is less than 7% of Rd (ρ) for 
. The calculations are performed for H–G phase function, g=0.9 and 
=0.01.
