ΔV_GC values between stars in the different disc components in the thin+thick simulation. V_GC (thin disc) – V_GC(intermediate disc) (left panel); V_GC(thin disc) – V_GC(thick disc) (middle panel), and V_GC(intermediate disc) - V_GC(thick disc) (right panel). Stars at |x|≤ 2.5 kpc and |y| ≤ 3 kpc from the Galactic centre are selected. Different latitudes are shown: b = 0°, − 2°, − 4°, − 6°, − 8°, and − 10°. The size of the fields is Δl = Δb = 1. °5.
