Comparison of disk images obtained with ADI (left column) and CDI (center column). For each disk, the ADI and CDI images are displayed using the same color scale; however, the scales vary from one disk to another. ADI and CDI results were obtained through the same dataset. We use K-klip ADI (Soummer et al. 2012) with K_klip = N_filt/2. Right column: comparison of disk intensities, for pixels inside the region encircled in green, obtained with both ADI and CDI as a function of the position angle.
