Notes. The column density is determined by averaging the emission inside the 3σ contour in 
of each molecule in each clump, assuming Tex = 20 K. In the first column, the mean VLSR of the clump is also indicated. The notation NA,ij means that the total column density of the molecule A is derived from the transition ij.
