Images showing the magnitude of ${\tilde{g}}_{\mathbf{u}}(x,0,z)$ in the x-z plane for the FRACT with parameter ξ = 0.51ρ, in the presence of finite sampling of the sphere and truncation of the spherical harmonic series. (a)-(d) Results using L = 8. (e)-(h) Results using L = 32. Results can be compared to the ideal response function shown in Fig. 2(b).
