List of optimized parameters from the velocity model.

(1) x (km s−1 pc−1) y (km s−1 pc−1) z (km s−1 pc−1) 0 (km s−1)
x 2.60 × 10−2 −8.83 × 10−4 7.82 × 10−2 5.04
y 2.35 × 10−2 2.87 × 10−2 2.53 × 10−2 22.19
z 3.97 × 10−2 3.51 × 10−2 3.46 × 10−2 −6.97

(2) x y z [km s−1]

σg 3.41 0.80 0.64
vf −4.80 14.76 -7.53
σf 67.26 24.03 109.77

(3) λg = 0.44

Notes. Panel (1): the optimized velocity field parameters in Eq. (4). The header of each row corresponds to the first subscript i of uij, and the header of each column names the second subscript j. The physical unit of each column is marked in the column headers. Panel (2): the components in the group velocity dispersion σg, the velocity of the field stars vf, and its velocity dispersion σf. All values have unit km s−1 in this sub-table. The coordinate system used here is ICRS. Panel (3): the combination factor λg for the likelihood function.
