Results of IPCA (left) and 3-rank PCA with ADI only (right) for the VLT/SPHERE dataset of HD 36112 (Ren et al. 2023). Three simulated companions at a separation of $0_{.}^{\mathrm{\prime }\mathrm{\prime }}6$ have been injected into the cube, with contrasts of 8 × 10⁻⁶, 1 × 10⁻⁵, and 2 × 10⁻⁵. White lines indicate their positions. Two squares are displayed to mark the locations of the two claimed protoplanets: a red square at $0_{.}^{\mathrm{\prime }\mathrm{\prime }}1$, indicating the candidate proposed by Reggiani et al. (2018), and a yellow square at $0_{.}^{\mathrm{\prime }\mathrm{\prime }}6$, referring to the candidate proposed by Wagner et al. (2019).
