Comparison between the contrast obtained with TRAP and three ANDROMEDA reductions for 51 Eri (left) and β Pictoris (right). TRAP has been run with 30% of available principal components, whereas the three ANDROMEDA reductions correspond to a protection angle of δ = 0.3, 0.5, 1.0 λ∕D. Separations below the inner-working angle of the coronagraph are shaded and should only be interpreted relative to each other, not in terms of absolute contrast, because the impact of coronagraphic signal transmission is not included in the forward model of either pipeline. The shaded areas around the lines correspond to the 16–84% percentile intervals of contrast values at a given separation.
