Injection of four synthetic companions (parameters detailed in Table 1) in the V471 Tau VLT/SPHERE ADI sequence. The locations of the injections are shown with white circles on the ADI-PCA residual images. Panel a: three ADI-PCA final frames with two, four, and eight PCs subtracted. Panel b: cropped frames centered on the injected companions after optimizing the number of PCs (as shown in Table 1) to maximize the S/N of eachcompanion. SODINN’s probability and binary maps clearly reveal the four planets (without false positives at 99% probability) as seen in panel c. Panel d: MLAR patches, used at the prediction stage, centered on each one of the injected companions.
