Table 1.
Mean value and dispersion for the initial Gaussian velocity distributions, as well as the covariance between U and V.
| Population | U | V | W | Cov[U, V] |
|---|---|---|---|---|
| [km s−1] | [km s−1] | [km s−1] | [km s−1] | |
| Thin disk | −4.23 ± σu(T*) | −14.67 ± σv(T*) | −4.78 ± σw(T*) | 22 |
| Thick disk | −29.82 ± 59.94 | −48.63 ± 34.69 | −6.43 ± 39.37 | −181 |
| Halo | −41.17 ± 120.46 | −123.34 ± 78.29 | −6.79 ± 78.31 | −995 |
Notes. T* is the total age of the star, which is the sum of the cooling time of the white dwarf and the age of the progenitor. The velocities are given in the heliocenric reference system.
