Survey coverage of the catalogues presented in this paper in galactocentric coordinates. In both panels, the colours indicate the different surveys (grey: LAMOST DR5; magenta: APOGEE DR16; red: RAVE DR6; blue: GALAH DR2; and green: GES DR3) and the relative density of observed stars (bins with less than five stars are left blank). To guide the eye, grey circles are placed in multiples of 5 kpc around the Galactic centre, the expected location of the Galactic bar (e.g. Bland-Hawthorn & Gerhard 2016) is indicated by the black ellipse, and a heliocentric Galactic longitude frame is over-plotted. Left panel: Cartesian XY coordinates. Right panel: cylindrical RZ coordinates.
