Number of eccentricities found in the solar neighbourhood for each v_kick, shown in a 2D histogram with ẽ bins of 0.05 and bins of 10 km/s on a logarithmic colour scale. For each v_kick = n ⋅ 10 km/s, we simulate 10³ objects using either the exponential disc (top row) or Gaussian annulus (bottom row) prior, and evaluate their orbits in between 40 Myr and t_max = 200 Myr. The resulting eccentricities are divided into prograde (left column) and retrograde (right column) orbits. The dashed lines show 1 and 2 times the circular velocity (v_LSR) at a solar radius.
