Contour map of normalized detection maps obtained with TRAP (f = 0.3) and ANDROMEDA (δ = 0.5λ∕D) for 51 Eri b. These maps must not be confused with a derotated and stacked image. They represent the forward model result for a given relative planet position on the sky (ΔRA, ΔDec), that is, the conditional flux of a point-source predicted by the forward model given a relative position, corresponding to a trajectory over the detector (all pixels affected during the observation sequence). The dark wings around the detection are not a result of self-subtraction, but purely a result of the fixed forward model position with respect to the real signal.
