Top: spectra of individual spaxels in synthetic coronagraphic HARMONI data at R ~ 7000 with a central A6 star and a 1700 K planet (orange) (see Fig. 1). Random spaxels (gray) in the corrected region illustrate the modulation by the speckles of the stellar spectrum, as shown with the central spaxel behind the semitransparent focal plane mask (blue). Details of the simulations are given in Sect. 3. Bottom: resulting spectra after the continuum was removed (following Hoeijmakers et al. 2018). The amplitude of the planet spectra has been amplified for visualization purposes.
