Total transmitted peel-off contribution δL_tot of radiating embedded spheres or points, inside a larger sphere of size  = 10^1.5. The orange and the blue curve show the contribution when using the extended and the basic peel-off method, respectively. The three gray vertical lines show the transition radii τ_r, where a differently sized sphere can be embedded. In particular, the left gray line gives the transition from using a sphere of size to a sphere of size . The middle line separates the τ^sph region from the region where the basic peel-off is used. Close to the rim of the sphere (i.e., to the right of the last gray line for radii τ_r ≲ ) none of the precalculated spheres fit and the basic peel-off method is applied.
