From top to bottom: distribution in the E − L_z, L_⊥ − L_z and R_min − R_max spaces of halo and thick disc stars from the Nissen & Schuster (2010) sample. As in Nissen & Schuster (2010), thick disc stars are indicated with black crosses, high-α halo stars with empty blue circles and low-α halo stars with red filled circles. Stars with an uncertain classification (see Tables 3 and 4 in Nissen & Schuster 2010) have not been included. As in Nissen & Schuster (2010), the components of the visual binary star, G 112-43 and G 112-44, are connected by a straight line. Energies are expressed in units of 10⁴ km²/s², angular momenta in units of 100 km s^-1/kpc, distances in kpc.
