Fig. 7
The three parts of the Ca ii triplet of the active star HD82443 (solid line) observed at high resolution by TNG/SARG and processed by GOG to simulate an RVS spectrum at the noise level of a G = 8 source. The dashed curve shows an NLTE synthetic spectrum for a pure photospheric contribution for comparison. Dashed vertical lines delimit the wings and the core regions.
