Notes. The following quantities are listed: mean absolute magnetic strength, maximum value of the magnetic field modulus, poloidal and toroidal magnetic energy as a fraction of the total energy, dipolar, quadrupolar, and octupolar magnetic energy as a fraction of the poloidal energy, axisymmetric magnetic energy as a fraction of the total energy, poloidal axisymmetric energy as a fraction of the poloidal energy, and toroidal axisymmetric energy as a fraction of the toroidal energy. The variation bars were computed by reconstructing ZDI maps and including the uncertainties on the input stellar parameters.
