On-sky coronagraphic PSF from the dgvAPP360 mounted on LBT/ALES at 3.73 μm. The IWA and OWA are shown by the two dashed circles in red. The area between them is the dark hole of the PSF where the planet is expected to be located. The image size of ALES is smaller than the OWA. The colourbar shows the flux intensity after background subtraction.
