Fig. 1


Typical CCF for the CEMP-s star HE 1120-2122 on HJD 2 456 804.428, based on a spectrum with an exposure time of 1800 s. The Gaussian fit of the CCF is the thin solid line, restricted to the CCF core to reduce the impact of line asymmetries as much as possible. The vertical line indicates the star radial velocity, as derived from the Gaussian fit.
