(U, V) plane for the observed stars. Left: (U, V) plane showing the position of the known kinematic groups in the solar neighbourhood. Large crosses represent the convergence point of the ‘classical’ moving groups. Coloured asterisks show the positions of the so-called ‘old’ moving groups. Our stars are shown by black filled star symbols. The dashed line represents the boundary of the young disc population as defined by Eggen (1984, Eggen 1989). The dotted line represents the velocity ellipsoid determined by Francis & Anderson (2009). Right: zoom onto the region of the (U, V) plane around the Local Association.
