Intensity profiles I(μ) /I(1) for α Cen A, α Cen B and the Sun. Top panel: the observed power laws I(μ) /I(1) = uα are represented with solid curves, together with the measured polynomial by Pierce et al. (1977, P77, black). The 3D model predictions are represented with dashed curves. Bottom panel: differences between the observed profiles and the 3D model predictions.
