Results of IPCA (left) and rank-2 PCA (right) both with ADI only, for the uncropped observations of HD 163296. The position of the candidate, inferred by Izquierdo et al. (2022) and Pinte et al. (2018) from a local deviation in Keplerian velocity, is marked by the yellow square with dimensions 60 × 60 pixels. A zoom into the 60 × 60 pixels aperture is displayed in the bottom left of each image, with the planet’s location indicated by an arrow on the smaller images. Five simulated companions at a separation of $2_{.}^{\mathrm{\prime }\mathrm{\prime }}2$ have been injected into the cube, with contrasts ranging from 1 × 10⁻³ to 3 × 10⁻⁶. White circle indicate their positions.
