Notes. The following quantities are listed: filling factor on Stokes V; 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 obliquity of the dipolar component relative to the rotation axis. To compute the local magnetic field (i.e., within a grid cell of the ZDI stellar model) the field strength should be divided by the associated filling factor fV.
