The absolute magnitudes of the multipolar components, ﹩| {a}_{lm}^{B,{\rm{in}}}| ﹩, arranged in descending order (dashed lines), together with the corresponding ﹩\delta { \mathcal C }﹩ values (solid lines) for the same cases as in Figure 1. The total number of multipolar modes, n_l, is shown on the x-axis. The legend at the top indicates the radial offsets, in units of R_⋆, of the dipole (r_D) and quadrupole (r_Q) components of the input field solution. The inset table lists the n_l values for ﹩\delta { \mathcal C }=1{0}^{-3}﹩ computed from the unordered and ordered ﹩| {a}_{lm}^{B,{\rm{in}}}| ﹩; only the ordered case (black dots) is shown.
