Comparisons of the mass functions at 18′′ of the bound sources extracted by getsf in the star-forming regions NGC 6334 with those extracted in the HD (blue) and MHD (red) simulations. In case of NGC 6334, only the sources from the central region (red box in Fig. 1) were used. The numbers of sources were normalised to the peak of the mass function for NGC 6334 and the fits of the cumulative mass function were done within the range 10−50%. In all modelhistograms, the numbers of sources were averaged between the x, y, and z projections.
