Sampling parameters for the initial conditions of the orbit integrations of Jhelum and the parameters of the four selected orbits used for the N-body experiments integrated with GADGET-4. For these integrations, α and δ were kept at a fixed value.

| d (kpc) | 12.6 ± 2.0 (b) | – | 10.7 | 11.1 | 11.6 | 10.7 |
 (mas yr−1) |
7.46 (a) | 0.51 | 7.74 | 7.45 | 7.31 | 7.50 |
| μδ (mas yr−1) | −5.10 (a) | 0.64 | −5.04 | −4.90 | −4.71 | −5.04 |
| vrad (km s−1) | −28.8 (c) | 13.8 | −25.7 | −39.3 | −24.8 | −25.4 |
Notes.
Errors for the Jhelum PMs were found by binning Gaia EDR3 data of Jhelum and the error for the radial velocity was taken equal to the ensemble variance of the selected Jhelum members in Ji et al. (2020). The properties for Jhelum were taken from the star labelled Jhelum2_2 in Ji et al. (2020).
