Notes. The columns show the number of stars, galactocentric distance, velocity, and half-mass radius. The last column indicates whether a significant fraction of the SC members managed to fall into the central half parsec within the estimated lifetime of IRS13 (see also Fig. 6). The Galactic plane is in the xy plane. Naming convention: [N0]-[x0/pc]-v[v0/km s−1]-[w (for wider SCs with rh,0 = 2 pc)].
