Table 2: Absolute velocities of the components are listed in Cols. 2-4. Proper motions and position angles of the components relative the core between 1992.83 and 1999.78 (except components B and D between 1991.63-1999.78) are listed in Cols. 6 and 7. Last two Cols. (8 and 9) represents the parallel and perpendicular components of the proper motions relative the core. The parallel component $\mu _{\parallel }$ indicates the vector component between the direction of $\mu $ and the position angle of the position vector relative the core as an average between the two epochs. The perpendicular component $\mu _{\perp }$ is orthogonal to that.
