ZDI reconstruction in flattened polar view of the large-scale field of HD 63433. From the left, the radial, azimuthal, and meridional components of the magnetic field vector are illustrated. The radial ticks are located at the rotational phases when the observations were collected, while the concentric circles represent different stellar latitudes: −30°, +30°, and +60° (dashed lines), as well as the equator (solid line). The geometry is complex, with a significant toroidal fraction and the poloidal component distributed mainly in the dipolar, quadrupolar, and octupolar modes. The colour bar encapsulates the magnetic field strength, up to a maximum of 55 G.
