Figure 9: Comparison of the time Fourier transform of Ψ0 and Ψ4 for two different radii of the outer boundary. The leveling off of Ψ0 for kM ≳ 3 is due to numerical roundoff effects (note the magnitude of Ψ 0 at those frequencies). Courtesy: Oliver Rinne. Reprinted with permission from [366]; copyright by IOP.
