Notes. The values include (a) the average magnetic field strength ⟨B⟩, (b) the unsigned peak magnetic field strength |Bpeak|, (c) the ratioof toroidal field energy to the total magnetic energy, (d) the ratio of magnetic energy in axisymmetric modes (m = 0) over the total energy, the same quantity but limited to the poloidal (e) and toroidal (f) magnetic component, the ratio of the dipole, quadrupole, and octopole (g, h, i) to the total poloidal component, and (ℓ = 1, 2, 3) subcomponents of the toroidal field energy, as percentages to the toroidal field energy (j, k, and l).
