FIGURE. 3.Velocity allipcoid parameters as functions of heigt above the Galactic disk for the complete sample of F-stars (left) and a young (t3 Gyr) metal-rich ([Fe/H]-0.13) group (reght). The curves give 1, 2, and 3 - the major, mean, and minor semi-axes of the ellipsoids, respectively; 2/1 is the velocity ellipsoid semi-axis ratio; l is the Solar apex galactic longitude; L1 is the longitude component of the vertex deviation; v, u, and w are the components of the space velocity of the group centroids with respect to the Sun - the axes are directed toward the Galactic center (u>), in the direction of the Galactic rotation (v), and toward the North Galactic pole (w). discussion in the text | next figure | previous figure |
