Angular distribution of Cherenkov emission as a function of absorption coefficient at 665nm, μ_a,665nm = (a) 0.1 cm⁻¹, (b) 0.3 cm⁻¹, (c) 0.5 cm⁻¹, (d) 0.7 cm⁻¹, and (e) 1 cm⁻¹, and reduced scattering coefficient at 665nm, μ_s’_665nm (from bottom to top: 5 cm⁻¹, 10 cm⁻¹, 15 cm⁻¹, 20 cm⁻¹, and 40cm⁻¹). Lambertian distribution function sin2θ is plotted and overlay on each simulation for different optical properties. I_Che,θ is defined as ∫∫∫ C_em(r, θ_e, λ, z₀)rdrdλdz.
