Distributions of ﹩{N}_{{{\rm{H}}}_{2}}﹩, ﹩{L}_{\mathrm{bol}}﹩, ﹩{M}_{\mathrm{clump}}﹩, and ﹩{L}_{\mathrm{bol}}/{M}_{\mathrm{clump}}﹩ in logarithmic scale for the selected 325 ATLASGAL clumps compared to the 919 total clumps. The range of physical parameters of the selected 325 clumps are well covered compared to the whole 919 clumps.
