Notes. The following quantities are listed: filling factor, mean magnetic strength, maximum magnetic strength, 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, and tilt of the magnetic axis relative to the rotation axis. The time span of the 2019 optical epoch is encompassed in the 2019b near-infrared epoch.
