Radial velocities of the primary (star A: filled symbols) and the secondary (star B: open symbols) of CS 22876–032 (upper panel), and residuals from the fit (lower panel). Triangles and circles are literature (Norris et al. 2000; González Hernández et al. 2008) and new UVES observations, respectively. The curves show the orbital solution (see Table 1) for star A (solid) and B (dashed). Triple dotted-dashed horizontal line shows the centre-of-mass velocity of the system.
