Top panel: Toomre diagram of the selected ks_thin disc (blue) and ks_thick disc (red) stellar samples, considering quality selection criteria, as in Figure 2. Middle panel: Same as the top panel but with stars with probabilities between 50% and 75% of belonging to the kinematic thick disc over plotted in orange. Bottom panel: Same as top panel but with stars with probabilities between 50% and 75% of belonging to the kinematic thin disc overplotted in green.
