Comparison of the face-on kinematics in the simulation snapshot and orbit superposition Model 1. From top to bottom: the mean velocities VR, Vϕ, Vz, and velocity dispersion components σR, σϕ, and σz. The left column corresponds to the snapshot data, the middle one depicts the orbit superposition, and the right column displays their residuals. The orbit superposition model reproduces kinematic features typical for MW-like barred galaxies, including the quadrupole VR pattern, the axisymmetric rise of the rotational velocity with distance from the centre, Vϕ, and the 2D velocity dispersion profiles with ≈10 km s−1 precision. At the same time, the model is unable to recover the spiral arms-induced velocity perturbations and a weak disequilibrium seen in the Vz maps.
