Magnetic field of Saturn
Saturn's magnetic field is unusual because it has almost no tilt. The rotation rate of the interior is therefore poorly known, so non-zonal spherical harmonics will be smeared out and averaged to zero. For this reason, only zonal spherical harmonic coefficients are used for these models. All models use only the g10 (dipole), g20 (quadrupole), and g30 (octupole) coefficients. The models used here can all be found in Russell and Dougherty (2010).
