Comparison of the observed (symbols connected with black lines) and synthetic (thin red lines) Stokes I (upper panel) and V (lower panel) profiles calculated for the final magnetic field and abundance maps. The distance between two horizontal tick marks on the upper axis of each panel is 0.1 Å, indicating the wavelength scale. Rotational phases are given on the right of both panels. The spectra are shifted vertically and ordered according to the rotational phase.
