Results of IPCA with ARDI (left) and rank-3 PCA with ADI only (right), for an injected companion at a separation of $0_{.}^{''} 31$ $\[0^{\prime \prime}_.{31}\]$ into the VLT/SPHERE dataset of HD 169142 (Ren et al. 2023), using a contrast of 1.5 × 10⁻⁵. The position of the simulated candidate is indicated by a red square, while the location of the actual candidate proposed by Gratton et al. (2019); Hammond et al. (2023) is marked by a yellow square
