Left: Spectral response functions, 𝒮_λ, for the PLATO (Sect. 2), Kepler (Van Cleve & Caldwell 2016), TESS (Ricker et al. 2014) (normalised to a maximum of Kepler), and CoRoT (Auvergne et al. 2009) missions as a function of wavelength λ. The shaded regions show blackbody spectra with temperatures of 7000, 6000, 5000, and 4000 K (normalised to a maximum of 0.8 for the hottest, or bluest, curve). Right: Spectral response functions for the PLATO N- and F-CAMs. The vertical dashed lines show the nominal passband limits of the blue and red F-CAMs, with the shaded ±10 nm regions indicating the potential variation in these from the incident angle.
