5-σ contrast curve. RSDI-PCA with correlation library (blue line) shows a better behavior than with ADI (red, green, and yellow lines); this corresponds to the components we used within this method. The library has 601 frames and it was created with N=50 and R=10, considering 70 principal components when applying the PCA. The contrast achieved with this library is 2.48 × 10⁻⁵ between 245 and 275 mas.
