Spaxel at the position of the planet before and after PSF subtraction with spectral PCA and aperture convolution (red and black), and spectral templates used to compute the molecular maps presented in Fig. 3. All spectra are shown after continuum subtraction. Additionally, they are normalised and offset vertically for readability. The shaded area between 2.24 μm and 2.3 μm represents the masked wavelength range where stray light is present.
