Height of the plane containing 75% of the mass at a given radius for all the simulated mass (left) and the simulated gas and newly formed stars (right) in MW3000HD (red) and F3000HD (blue). In grey, we present height for stars in the Milky Way potential, i.e. the underlying, not explicitly simulated mass distribution. Shaded regions indicate 16th to 84th percentile. In all simulations, stars are more concentrated to the disc plane than gas.
