ASDI reduced images using different ADI algorithms for a point source at 400 mas (23 px) in the original images with F1/F3 = 1.1. The LOCI coefficients derived to minimize the noise in the science data cube were applied on the noise-free image with the artificial source. For the PCA reduction, the artificial source was injected into the science data cube. All images have been normalized to their peak value. The scaling made use of the bytscl IDL function and is identical in the panels.
