Final result of post-processing with PCA (left) and the three terms of the LLSG decomposition (middle and right) for β Pic NACO data. 38 PCs were used to maximize the S/N for β Pic b in the full-frame PCA approach. For the LLSG decomposition a rank of 10 gave a significant improvement on b’s S/N (see Fig. 4). All the frames were normalized to the maximum value of the LLSG sparse frame (middle panel).
