Distance (top panel) and [Fe/H] (bottom panel) distributions for each of the Galactic components of the stars in the solar neighbourhood from the perfect GUMS sample. There are ~ 4784319 stars in thisdataset, 9240 of which are halo. The halo stars have a roughly constant distribution out to a distance of ~ 8 kpc from the Sun. While they span a large range of [Fe/H] value, the bottom panel shows that the halo stars are on average more metal-poor than stars belonging to the other Galactic components.
