caption: Reconstructed images of HD 199178 at epoch 1999.02, in flattened polar view. The concentric circles correspond (starting from the outside) to parallels of latitude -30°, 0° (equator, bold line), +30° and +60°. The upper-left panel corresponds to a brightness image, while the three other charts show the components of the magnetic field (in Gauss) in spherical coordinates, i.e. radial, azimuthal and meridional components of the field in the upper-right, lower-left and lower-right charts, respectively. <PERSON> and V normalized profiles are plotted in the lower part of the figure (left-hand panel and right-hand panel, respectively). Thin lines represent the observed profiles, while bold lines correspond to profiles reconstructed by the imaging code.
