From top to bottom: Toomre diagram, E − Lz, ecc − Lz and Rmax − zmax planes for stars of LP First stars (black dots), compared to the Sestito et al. (2019) sample (yellow stars, first column), the Nissen & Schuster (2010) sample (orange squares, middle column), and the Gaia DR2-APOGEE sample (density map, right column). The vertical dashed lines separate prograde from retrograde motions. Velocities are in units of km s−1, distances are in units of kpc, angular momenta are in units of 100 kpc km s−1, and energies in units of 100 km2 s−2.
