Notes. The ages of the clusters were obtained from Pang et al. (2022a, 2021a, 2024, 2022b, 2021b), derived via the PAdova and TRieste Stellar Evolution Code (PARSEC) isochrone fitting. Col. 3 lists the morphological type from Pang et al. (2022b). Cols. 4–6 present the fractal dimensions of open clusters for the all-member region, for the region inside the tidal radius r ≤ rt, and for the region outside r > rt, respectively. The fractal dimension of some open clusters in specific regions was considered invalid due to their low number of member stars (see Sect. 4). The full table is available at the CDS.
