Underlying spectra of the two components from the simulated system presented in Fig. 1 at a random epoch (red and blue upper spectra), next to the resulting observed spectrum (lower spectrum in black). The spectral parameters for the two components are a T_eff of 5500, and 6500 K, a log g of 6.0 and 5.0, Fe/H of 0.5 and 0 dex, and v sin i of 9 and 2 km s⁻¹, respectively. The spectra are normalized to a continuum level of zero. To enhance clarity, the spectra are presented here in arbitrary units, and a vertical offset was applied to the plot to separate them visually.
