Surface brightness distribution maps in Mollweide projection obtained from the simultaneous reconstruction of the observed light curve and LSD profiles (upper panel), from LSD profiles only (middle panel), and from the light curve only (lower panel). The blue and green tick marks indicate the longitudinal positions covered by the spectral and photometric data, respectively, shown in terms of rotational phase (ℓ = 360 × (1−φ)). The gray-shaded region indicates the invisible part of the southern hemisphere owing to the axial inclination.
