Residuals between the HR 3549 scientific data and the model of the stellar leakages near the companion (defined by the black rectangle in the bottom of Fig. 7) and for the complex model of the spatial and spectral dispersion laws after one iteration (top) and after convergence (middle) of EXOSPECO. The rms of the residuals in this region are significantly reduced after convergence. The orange dashed line indicates the position of the companion at the different wavelengths. The SEDs of the companion (including atmospheric absorption) extracted from these residuals are plotted in the bottom-most panel.
