\caption{
Line-integrated intensities in [$\kkms$] (upper table) and  in [$10^{-7}$ erg~s$^{-1}$~cm$^{-2}$~sr$^{-1}$] (lower table) of the low- and mid-$J$ 
CO isotopomeric lines and of the CS~$7\TO6$ line observed at KOSMA and FCRAO.
In order to prevent the $+9~\kms$ velocity component from adding to the integrated intensity,
the listed intensities were integrated only over the $-3~\kms$ component.
As the $^{12}$CO lines merge with the second velocity component, these spectra were fitted using a 2-component Gaussian
%are integrated over $-20~\kms$ to $4~\kms$, or were gaussian-fitted this component.
with the $+9~\kms$ velocity component masked out.
%The low- and mid-$J$ CO, the \CIw{} $2\TO1$ and $1\TO0$
All line intensities are reported for~$80''$ angular resolution (higher angular resolution data have been smoothed).
