Estimated spectra using PACO ASDI of the known real faint point sources of the considered datasets (top: HR 8799 c–d–e, middle: β Pictoris b, bottom: HD 131399 Ab). The inserts show a residual wwS/N map after “cleaning” the contribution of the detected sources. Synthetic subpixel views (4 nodes per pixels) show with false colors the aggregated flux of the detected sources along the different spectral channels (blue for ℓ₁ = 0.9575 μm and red for ℓ_L = 39 = 1.6357 μm).
