Top panel: MDF (left) and ADF (right) of the inner 6 kpc of the model. The curves correspond to the Gaussians assigned to the cold disc (solid), the intermediate disc (dashed) and hot disc (dashed-dotted). Bottom panel: [α/Fe] vs. [Fe/H] plane for our model inside 6 kpc, separating into particles in the inner 3 kpc and those between 3 < r < 6 kpc. We also separate into three vertical bins as indicated at the top of each panel. The grey colour corresponds to values below 5%.
