Orbital parameters derived with three pattern speeds of bar potential.
| Outputs | Rperi (kpc) | Rapo (kpc) | Zmax (kpc) | e | E (kpc Myr−1)2 | Lz (kpc2 Myr−1) |
|---|---|---|---|---|---|---|
| Ω = 41 kpc−1 km s−1 | 3.59 ± 0.8 | 14.98 ± 3.53 | 6.3 ± 2.06 | 0.6 ± 0.02 | −0.14 ± 0.014 | −1.27 ± 0.3 |
| Ω = 50 kpc−1 km s−1 | 3.63 ± 0.83 | 15.14 ± 3.61 | 6.36 ± 2.15 | 0.61 ± 0.01 | −0.14 ± 0.01 | −1.24 ± 0.29 |
| Ω = 60 kpc−1 km s−1 | 3.5 ± 0.8 | 14.5 ± 3.37 | 6 ± 1.99 | 0.61 ± 0.02 | −0.14 ± 0.01 | −1.29 ± 0.3 |
Notes. Different pattern speeds lead to similar orbital parameters, suggesting that the influence of bar potential is weak, in agreement with the fact that FSR 1758 did not enter the bar region.
