Distribution of the systems in the (U,V) plane, with the same labels as in Fig. 1. System 17 (01083+5455) falls outside the boundaries, at U = −43 km s^-1 and V = −157 km s^-1. To fix the ideas, two velocity ellipsoïds are shown, both centred on the reflex solar motion in the LSR: −U_⊙ = −10.2 km s^-1, −V_⊙ = −20.5 km s^-1, and with σ_U = 34.5 km s^-1, σ_V = 22.5 km s^-1, as derived by Famaey et al. (2005) from their most precise sample. Horizontal bands and the corresponding labels are used in Fig. 10.
