Fig. 3
The distribution of heliocentric radial velocities. The solid black line shows the distribution for spectra with no notation in Table 1, the dashed black line shows the distribution for spectra showing a G-band and the solid grey line shows the distribution for noisy spectra. The heliocentric radial velocity of ω Cen is marked by the dotted line at 232.2 km s-1 (Harris 1996).
