Caption: Figure 5.
Two spectra of 73 Leo, but at different phases (one at the giant’s velocity maximum, the other near its velocity minimum). The spectrum of a secondary component will have moved in antiphase to that of the primary, giving rise to changes in some line profiles since blends would have been created differently. Such changes are not in evidence.
