XY projection of the star cluster galactocentric positions, while arrows show the V_X, V_Y velocities (with velocity scale reported in the bottom left corner). Galactocentric coordinates were obtained by direct deprojection of the 6D coordinates listed in Table 4. Each cluster is color-coded according to the structure it belongs to: orange diamonds for W345, purple circles for LISCA I, and green squares for LISCA II . The blue lines show the Perseus spiral arm model (solid) by Reid et al. (2019), with once (dashed) and twice (dash-dotted) the arm width. The background grid is a heliocentric polar grid with the dashed gray lines showing distances from 1 to 4 kpc, and the dotted lines sampling the angular direction every 15 degrees.
