Final result of post-processing the synthetic HARMONI data with a cross-correlation with the planet spectral template (left) and spectral unmixing through orthogonal subspace projection (middle and right). The number of spectral signatures is set to eight to decompose the data. The injected mock planet has a broadband contrast of 5 × 10⁻⁶ with the central star at a separation of 100 mas (white circle). Images are normalized to the peak value of the planet for each algorithm, the scale is linear, the field of view is identical, and the white cross marks the position of the star.
