\caption{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.\label{tab2}}
