Velocity profiles for the stars of the sample by galactic component at z = 0. Each row shows the profiles for a given direction (tangential velocity, radial velocity, and vertical velocity) and the standard deviation (from top to bottom); each column shows the profiles for a given component (halo, bulge, cold disc, and warm disc, from left to right). Au6, as it is the reference galaxy, is highlighted in black. The vertical velocity is calculated as $v_z^{†}=v_z\mathrm{s}\mathrm{i}\mathrm{g}\mathrm{n}(z)$ to distinguish between inflows ($v_z^{†}<0$) and outflows ($v_z^{†}>0$).
