$^{1}$  \Vlsr\ and $d_{\rm kin}$ from \AMM\ observations (Molinari et~al.~\cite{mol96}). 
$^{2}$  \Vlsr\ and $d_{\rm kin}$ from \AMM\ observations (Sridharan et~al.~\cite{sridharan}). 
$^{\dagger}$  Between brackets, the offset (in arcsec) of the \H\ (1--0) line emission peak 
with respect to the map center (coordinates in Cols.~2 and 3) is given. 
$^{\clubsuit}$  Detected in the \D\ (2--1) transition only. 
(?)  Marginal detection. 
$^{a}$  Observed by Beuther et~al.~(\cite{beuther}) at 1.2~mm. 
$^{b}$  Observed by Williams et~al.~(\cite{williams}) at 850 $\mu$m and/or 450 $\mu$m.
