\tablefoot{Velocities and line widths, with the errors estimated by the Gaussian fitting 
algorithm in CLASS are provided in Cols.~2 and~3.  Making the assumption 
that the cloud radius is equal to the beamsize, virial masses are calculated as in 
\citet{Braine_n4414b} and the errors using only the uncertainty in $\Delta V$.
Masses from the CO(1--0) line intensity are given in Col.~5 using the line 
area from Table~\ref{tab2}a and a ``standard'' galactic conversion $\ratio = 2 \times 10^{20} \Xunit $. The first 4~clouds have Gaussian fits made using the 2.6~km~s$^{-1}$ channel width whereas 
the latter 7~fits have been made using data at 0.52~km~s$^{-1}$ channel width.  Cloud 8 
appears to have two velocity components, producing the broad line.  
Cloud~2 has a large error associated with the CO(1--0) observation; 
the Gaussian fit to the CO(2--1) line yields a width of $2.2\pm0.44$~km~s$^{-1}$
but the CO(2--1) beam is much smaller and may not include all the emission.}
