Space distribution of all the observational data used in this work. The red dot shows all the low-metallicity stars based on CaHK magnitudes and the blue dot shows the stars with rotation-dominated orbits 1000 < Jϕ < 2500 km s−1 kpc & Jz < 400 km s−1 kpc. The two circles are the same with those given in the right-most panel of Figure 7.
