Histograms of retrograde and prograde stars are presented in terms of elemental abundances and orbital parameters. The retrograde stars show a metal-poor peak at ∼ − 0.6 and are more metal-poor than prograde stars. The retrograde stars are also slightly more [C/N]- and α-enhanced than prograde stars, indicating that they are relatively older. The retrograde stars are mainly confined to within r_GC ∼ 2 kpc, while the prograde stars have a large r_GC of more than 3 kpc. Both retrograde and prograde stars have Z_max < 3 kpc.
