\tablefoot {The first two columns give the HEC name and the subgrouping of clouds based on the kinematic distance, the following columns represent (in~order of appearance): radius of the cloud, average visual extinction derived from the extinction maps, average hydrogen column density derived from the extinction maps, integrated 1.2~mm flux, cloud mass derived from the extinction maps, cloud mass derived from the 1.2~mm, clump peak flux and median cloud flux, class of~HEC. \\
\tablefoottext{a}{Radius is the square root of the area divided by~$\pi$. For the conversion to parsecs we use the kinematic distance based on the \amm(1,~1)~line.} \\
\tablefoottext{b}{Peak of the 1.2~mm emission in the clump and the mean 1.2~mm emission of the cloud without the clumps.}}
