Coronagraph transmission profiles for IFS YJH. Shown here are the results of the bivariate spline interpolation to the IFS YJ and IRDIS H23 measured values, at each of the IFS YJH wavelengths. The interpolations for the first and last wavelength of IFS YJH are highlighted. The 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).
