Coronagraph transmission profiles for IRDIS H23 (left) and K12 (right). Shown here are the measured values taken on-sky with seeing conditions of ~0.8 arcsec (A. Vigan), as well as the cubic spline interpolation to these values. These interpolations were treated as radial profiles to create coronagraphic transmission images, in order to directly correct the HD 112863 science frames (see Sect. 3.2.2). Also shown are the equivalent ρ at 10 pixels, 20 pixels, 30 pixels, accounting for the difference in pixel scale between each band.
