Notes. The fifth to ninth columns list the fraction of the large-scale magnetic energy reconstructed in the poloidal field component, the fraction of the poloidal magnetic energy stored in the dipolar (l = 1), quadrupolar (l = 2) and octopolar (l = 3) components, and the fraction of the energy stored in the axisymmetric component (m = 0).
