High-resolution spectra computed by the model. Top rows: broadened spectra by star rotation in the case of immaculate photosphere (blue), the complex activity scenario (orange), and the spots-only scenario (green). Bottom row: same as top rows, but without considering the rotational broadening in the computation. For comparison purposes, absolute fluxes (left panels) are presented together with the normalised ones (right). The normalisation trend has been evaluated with a Gaussian filter of 1200 Å as sigma.
