Scientific paper

Theoretical spectrum computations for the G-type dwarf HD 209458 and the K-type dwarf HD 189733 are presented, based on 3D hydrodynamical models of the stellar atmospheres. Surface intensities were computed in LTE using the SCATE spectrum formation code and cover the wavelength region between about 910 Angstroem and 20 micron with constant sampling of R=λ/δ_λ=20,000. The stellar disk was sampled at the disk center (μ=cos(θ)=1.0) and at angles μ = 0.90, 0.80, 0.70, 0.60, 0.50, 0.40, 0.30, 0.25, 0.20, 0.15, 0.125, 0.1, 0.075, 0.05, 0.025, 0.01 towards the limb. Use integration weights 0.05, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.075, 0.05, 0.05, 0.0375, 0.025, 0.025, 0.025, 0.025, 0.02, 0.0125 to obtain fluxes.
