Wavelength calibration of the model on the HR 8799 (YH-mode, on the left panel) and the RY lup (YJ-mode, on the right panel) datasets (colour bar: arbitrary unit). a,b: coloured projection ⟨x⟩_λ of the reconstructed hyperspectral cube. c,d: slice of the reconstructed hyperspectral cube (λ = 1314 nm for the HR 8799 dataset, λ = 1122 nm for the RY lup dataset). e: median intensity ℳ_θ(x) computed on each slice of the reconstructed hyperspectral cube for each dataset compared with the reduction proposed by Vigan et al. (2015). The wavelengths of the calibration lasers are highlighted by dashed grey lines).
