Notes.

^(a)

NOMAD catalogue (Zacharias et al. 2004).

^(b)

Radial velocity measured in our CTIO spectrum. The other spectra show line doubling with radial velocities of 85.26 and 108.7 km s^-1 (FEROS), 79.78 and 113.8 km s^-1, 74.68 and 120.0 km s^-1 (HARPS), respectively.

^(c)

γ-velocity of DD Vel from Metzger et al. (1992).

^(d)

Distance derived from the apparent magnitude in the J band (2MASS) and the period-luminosity relation of Matsunaga et al. (2006).
