Distribution of velocity components (V_R in left, V_ϕ in the middle, and V_z in the right) in the galactic rest frame within three 2 kpc-wide annuli centred at 1 (top), 8 (middle), and 11 kpc (bottom). The snapshot data are represented by the grey-filled areas, while the results of the orbit superposition based on Mock 1 and Mock 2 are depicted in blue and red colours, respectively. The blue and red-filled areas correspond to the initial mock data. For each panel, the numbers correspond to the mean and standard deviation of the velocity distribution in km s⁻¹. We emphasise that the orbit superposition method we employ aims to recover the approximated stellar density distribution; the figure shows that Model 1 reproduces the kinematic information very well. At the same time, this approach is unable to capture spiral arms or the non-equilibrium kinematic features of the disc and bar. Furthermore, the effectiveness of the orbit superposition technique is contingent upon the accuracy of the potential approximation.
