Fig. 1

HARPS spectrum of HD 161701 taken near quadrature at φ 0.215 (in black, shifted vertically by 0.4). Several spectral lines of the primary and secondary components are marked with blue ticks and red arrows, respectively. For a better visualization of the composite spectrum, the reconstructed spectra of the primary (blue) and secondary (red) stars are overplotted in the lower part.
