Table 2
Overview of the Jacobi radii, rJ, and masses, MJ, alongside the bound mass fraction of the four clusters where we find a bound core; see Sect. 4.4 for more information.
| SID | Literature | rJ | MJ (a) | Bound mass fraction (b) |
|---|---|---|---|---|
| name | (pc) | (M⊙) | (%) | |
| 4 | Platais 9 | 5.9 | 79.5 | 32.1 |
| 7 | NGC 2451A | 7.7 | 170.2 | 39.1 |
| 8 | Mamajek 2 | 5.1 | 56.0 | 33.2 |
| 11 | OCSN 3 | 4.6 | 44.2 | 36.9 |
Notes. (a)The Jacobi mass is determined using the observed masses (see Mtot) and not the system masses that are derived from fitting a Kroupa IMF to the observed mass histograms. (b)The boundedness fraction is determined by dividing the Jacobi masses by the observed system masses, i.e., Mtot as provided in Table 1; see also footnote (a).
