Table 6
Orbital parameters of the Sagittarius dSph.
| Model | d | da | dp | t | vc(R⊙) |
|---|---|---|---|---|---|
| RAR 1 | 24.57 | 60.21 | 13.70 | −3.0 | 199.4 |
| RAR 2 | 25.64 | 60.17 | 14.35 | −3.22 | 215.0 |
| RAR 3 | 25.88 | 60.22 | 14.87 | −2.7 | 213.4 |
| Burkert | 25.3 | 60.14 | 14.27 | −2.75 | 214.5 |
Notes. The values in the table correspond to the orbit integrated backward in time under different gravitational potentials. d stands for the initial distance to the progenitor, da for the apocentric distance, dp for the pericentric distance, t for the backwards integration time, and νc(R⊙) for the circular velocity at R⊙. Distances are in kiloparsecs, the time in gigayears, and the circular velocity in kilometers per second.
