Residual UVES Hα profiles (black dots). The totally blended emission from the two stars is represented, in each box, by a magenta dashed line, while the brown dashed line is the Gaussian fitted to the excess blueshifted or redshifted emission. The sum of the two Gaussians is overplotted as a full green line. The blue and red vertical ticks mark the expected position of the lines of primary and secondary component, respectively, according to the photospheric RV.
