5σ contrast plot with the IFS operating in YJ-mode for bright star observations after PCA data reduction and with simulated ADI procedure. The solid black line represents the contrast before speckle subtraction, the green line represents the contrast after PCA data reduction method using only the 4 principal components and without any rotation (see Fig. 11). The red line is obtained applying the PCA method with 32 principal components and with simulated FOV rotation (see Fig. 12).
