Scientific paper

We study the velocity distribution of the extended solar neighbourhood with 50,000 He-burning red clump stars in RAVE. Trends as a function of Galactocentric radius,R, and height above the plane, Z, are investigated for the first and second moments of the velocity components, as well as a measure of the strength of the Hercules moving group. A relative rotation curve is also derived and the dependence of the vertex deviation and velocity ellipsoid tilt as a function of Z is obtained. These results demonstrate how now moving away from the immediate solar vicinity for detailed kinematics of stellar populations we can further probe the Galactic potential and heating processes.
