Table 6
Deviations (in percent) between existing and newly derived orbital elements for the most prominent dusty objects of the S cluster.
| Source | ∆a | ∆e | ∆i | ∆ω | ∆Ω | Δtclosest |
|---|---|---|---|---|---|---|
| G2/DSO | 0.11 | 0.20 | 0.59 | 1.12 | 0.90 | 0.00 |
| D9 | 0.71 | 0.66 | 0.56 | 7.20 | 0.11 | 0.54 |
| X7 | 0.01 | 0.00 | 0.46 | 0.61 | 0.23 | 0.00 |
Notes. We used the Keplerian elements based on observations until 2019 (classified as old in Table 4) as a reference and calculated the percentage of the deviations compared to the updated values. We used the averaged individual Keplerian elements of the indicated uncertainty range. The absolute uncertainties were estimated using MCMC simulations (see the appendix) and exceed the values listed here.
