RVs determined by simple fits (top) and by finding the best shift of fixed Gaussians (bottom left). Small cyan symbols correspond to WIRO data, other symbols are the same in all panels, with one colored symbol for each line. The RV measured for a narrow interstellar feature is superimposed on the He ii λ 4686 Å subpanel using asterisks, to show the quality of the wavelength calibration. The bottom right panel shows the RVs determined by disentangling. The best-fit orbital solution (Table 3) found from disentangling is superimposed on each panel.
