Orbital calculations for VVV-CL001. We show the most likely current position (large orange circle) and the corresponding orbit (white curve) showing its past −150 Myr orbit (solid) and future 150 Myr orbit (dashed) seen in the X −Y plane view (top panel) and the X −Z view (bottom panel). To avoid crowding we show a subsample of 20 randomly selected orbits from the total of 10⁴ orbits, giving their current positions (smaller circles), their past orbits (green) and future orbits (purple). The density probability (color map) shows the regions that the orbits inhabit. The stellar surface mass density contours of the MW bar and inner disk model of S22 reveal that this cluster lives between the inner disk and the bulge–bar region. We also plot the Sun’s position. We note that in this frame the MW and the bar rotate clockwise, with the bar havings a rotation period of T_bar =157 Myr.
