Left panel: Toomre diagram of sample. The 2σ contours of the thin disc (grey), the thick disc (green), and the halo (blue) are constructed from the U, V, and W distributions of Anguiano et al. (2020). Objects with halo kinematics are marked in blue; the few objects also consistent with thick-disc kinematics are marked in green. Right panel: e − L_Z diagram of the sample using the same colour coding for the stars. The green and grey 2σ contours in the upper left denote the locations of thin- and thick-disc stars, respectively, based on the GALAH + Gaia EDR3 sample of Buder et al. (2021). The dashed lines mark prograde (positive L_Z) and retrograde (negative L_Z) directions of Galactic rotation, respectively.
