Vertical distance from the Galactic plane (Z) as a function of galactocentric distance (R). We also show the respective normalised distributions of R and Z. The thin-disc, high-α metal-rich, and high-α metal-poor thick-disc populations are shown in orange, purple, and blue, respectively. This separation into three stellar components is discussed in Sect. 4.
