Ensemble of one million orbits in the frame corotating with the bar for the CWNU 4193 cluster, projected on the equatorial (top) and meridional (bottom) Galactic planes in the non-inertial reference frame with a Ω_bar of 31 (left), 41 (middle), and 51 (right) km s⁻¹ kpc⁻¹ and time-integrated backwards over 2 Gyr. The yellow and orange colours correspond to more probable regions of the space, which are most frequently crossed by the simulated orbits. The solid inner white circle and the dashed outer circle in the top panels show the locations of the CR (see text) and the solar orbit, respectively. The white dots mark the positions of the Lagrange points of the Galactic bar, L₄ and L₅, and the current position of the Sun, respectively. The horizontal solid white line shows the extension of the bar (R_c~3.28 kpc; Robin et al. 2012) in our model. The black-filled and unfilled star symbols indicate the initial and final positions of the cluster in our simulations, respectively. The solid black line shows the orbital path of the CWNU 4193 cluster from the observables without error bars.
