Location of the 161 clean HRV sample stars, in four different diagrams: (top left) Toomre diagram, (top right) eccentricity versus total velocity, (bottom left) energy versus vertical component of the angular momentum, and (bottom right) maximum versus minimum distance to the Galactic centre. The 108 confirmed HRV stars are represented by cyan filled circles and the 53 Gaia DR3 stars with S/N > 10, by blue stars. The density maps are made of APOGEE DR17 stars.
