Fragmentation level as a function of clump properties of sources located at a distance of 2−4 kpc (dots) and 1−2 kpc (triangles). In each plot, data points are color-coded according to the clump size. Dashed contours show the distribution of sources at 2−4 kpc from a Gaussian kernel density estimation. Left: number of fragments as a function of clump mass. Middle left: specific fragmentation level (normalized by the size of the parent structure) as a function of the luminosity-to-mass ratio of the clump. Middle right: specific fragmentation level as a function of the clump density. Right: number of fragments as a function of the predicted number of fragments based on a Jeans fragmentation scenario. Gray dashed lines mark the lines of N_mm = 0.15/0.05/0.01 × M_clump/M_{Jeans, clumpTd}.
