Fig. 2


Radial velocity curve of Feige 87, showing the spectroscopic orbital solution (solid line: MS, dashed line: sdB), and the observed radial velocities (HERMES: blue circles, Barlow et al.: green squares, filled symbols: MS component, open symbols: sdB component). The measured system velocities of both components based on the HERMES data and the MS radial velocities of Barlow et al. are shown by a dotted red line, while the system velocity of the sdB component based on the data of Barlow et al. is plotted in a green dotted line.
