Left: Radial magnetic field of HD32633. From top to bottom: original field recovered from published plots, original field fitted with spherical harmonics, and original field fitted with an independent code by C.D. Beggan (British Geological Survey, Edinburgh). The phases differ by 180° between the two codes. Right: Horizontal magnetic field of HD32633. From top to bottom: original field recovered from published plots, horizontal field derived from the radial field by assuming a potential poloidal force-free configuration, and horizontal field derived similarly with the independent code by C.D. Beggan.
