 \begin{list}{}{}
  \item[$^{(1)}$] The statistical uncertainties in parenthesis are given in 
  units of the last digit. 0 means the parameter was fixed. For 
  $V_{{\rm lsr}}$, they include the contribution of the frequency 
  uncertainties listed in Table~\ref{t:results}.
  \item[$^{(2)}$] The non-thermal linewidth was computed assuming 
  $T_{{\rm K}}$ = 10 K and, for the Gaussian fits, optically thin emission.
