Molecular templates after removal of the continua (H₂O in blue, CO in red, and CH₄ in green) and residuals of the data at the position of the planet (gray). No broad feature is visible and only individual absorption lines at the instrument resolution are cross-correlated. The small black dash in the top left corner of the first three panelsrepresents the filter size for continuum removal. Features smaller than this are kept in the residuals, while larger structures are removed as part of the continuum.
