Final result of post-processing with PCA (left), annular PCA (middle), and our LLSG decomposition (right). The images were normalized to their own maximum value. Four synthetic companions a(285°), b(185°), c(5°), and d(85°) were injected at 2, 5, 8, and 13 λ/D from the center, respectively. The injected PSFs were scaled at 0.5, 5, 5, and 7 times the noise of the respective annulus. We used 13 PCs when applying full-frame PCA and 25 PCs for the annular PCA (applying the same number of PCs in every annulus) in order to maximize the S/N of the innermost fake companion in each case.
