Evaluation example of Annular-PCA and all SODINN-based algorithms over the 5-7 τ/D regime of sph2, where a fake companion has been injected with S/N=0.75 (computed in the PCA-processed frame using the first principal component). Each row corresponds to a different algorithm, where its detection map is on left column, and its three thresholds (binary maps) are on the right. The threshold τ, TPs and FPs are highlighted over each binary map. White concentric circles indicate the regime’s boundaries. Other noise regimes are masked. Small green circles indicate the position of the injection.
