Detection rate as a function of clump mass ﹩{M}_{\mathrm{clump}}({M}_{\odot })﹩, bolometric luminosity of central objects ﹩{L}_{\mathrm{bol}}({L}_{\odot })﹩, luminosity-to-mass ratio ﹩{L}_{\mathrm{bol}}/{M}_{\mathrm{clump}}({L}_{\odot }/{M}_{\odot })﹩, and peak H₂ column density of clumps ﹩{N}_{{{\rm{H}}}_{2}}({\mathrm{cm}}^{-2})﹩ in logarithmic scales. The values on the x-axis for these parameters correspond to the bin values from the second to the end value, while ﹩\mathrm{log}{N}_{{{\rm{H}}}_{2}}﹩ shows bin values on the top x-axis from the second to the end. The bin values and detection rates are presented in Table 5.
