Top row: positions of Hyades members in Galactic Cartesian coordinates. The X-axis points toward the Galactic center, Y is positive in the direction of rotation in the Galaxy, and Z points to the Galactic poles (positive toward the north pole). The Sun is located at (0,0,0). While the fully opaque blue points refer to our final member selection, the gray dots in the background represent all sources. Bottom row: velocity vectors for the selected Hyades members in the Galactocentric cylindrical frame. The Sun’s position is indicated with the black circular symbol. The vector lengths are proportional to the velocities, as indicated in the embedded legends.
