Residuals between the HR 3549 scientific data and the model of the stellar leakages, assuming a standard (top figure), medium (center), and complex (bottom) calibration models. The rms values of the residuals are given for each model. The iso-levels of ρ / λ which are approximately followed by the dispersed stellar speckles are plotted as green dashed lines. The position of the companion at the different wavelengths (i.e., at ρ = ρ_⊕) is plotted as an orange dashed line.
