(\cite{olofsson98}).\\ $^{{b}}$ From the SIMBAD data base but since the velocity differs from molecule to molecule and due to the variability of SiO~masers, different values can be found in other references. Some references are, 9.6$-$12.5~\kms\ from CO by Olofsson et~al. (\cite{olofsson91}); 11.8~\kms\ from CO, 9.8~\kms\ from SiO ($v=1,J=2{-}1$) by Cernicharo et~al. (\cite{cernicharo}); mean velocities of 10.7$-$11.0~\kms\ from SiO ($v=1,2,3, J=1{-}0$) by Cho et~al. (\cite{cho}).\\ $^{{c}}$ Benson et~al. (\cite{benson90}); Benson \& Little-Marenin (\cite{benson96}); Lewis (\cite{lewis}). \end{table}
