Left: mass of the most massive fragment as a function of clump properties for sources at a distance 2−4 kpc (dots) and 1−2 kpc (triangles). Left: mass of the most massive fragment as a function of the luminosity-to-mass ratio of the clump. Vertical lines mark the luminosity-to-mass ratios of 1 and 10. Middle: mass of the most massive fragment as a function of clump mass. Gray lines show the 30% and 100% proportion of the clump mass, and the blue line shows the result of a linear fit on a logarithmic scale to sources in a 2−4 kpc distance range of Mfragments = 0.87log Mclumps − 0.21. The left and middle plots share the same color bar. The clumps are color-coded according to their sizes. Right: surface density of the most massive fragment as a function of clump surface density. The gray line marks the line of equality, and the blue line shows the result of a linear fit to sources in a 2−4 kpc distance range of log Σfragments = 1.51log Σclumps + 1.13. The different sizes of the markers correspond to the size ratios between the size of the parental clump and the size of the most massive fragment, as indicated in the legend, that is, the smaller the size of a marker, the larger size difference between a fragment and its parental clump, up to a factor of 5.
