Clump mass functions for different α with f_DGMF = 0.4. The grey solid lines show the distributions sampled, while the coloured lines show the actual realisation. The vertical lines show the values at which the CMF changes in slope. As the slope of the function steepens, more clumps are selected from the lower-mass range. This leads to a progressive increase in the numerical noise in the sampled population at higher masses with increasing α, as seen in the plot.
