Overview of the young debris disk around HD 120326. The black-to-white images are the S/N map of the optical HST/STIS coronagraphic data, with a spatial binning 2 × 2 pixels² → 1 × 1 pixel². For reference, in the center of the images we display the inner structures detected with SPHERE in total intensity (top), in polarimetry (middle) and with ALMA (bottom). The areas hidden by the coronagraphs and the HST diffraction spikes are masked in dark gray.
