Comparison of the prestellar CMF observed in Orion B (black triangular data points and histogram from Könyves et al. 2019; see also Fig. 3) with the global prestellar CMFs expected in the toy model of Sect. 3, under three assumptions about the shape of the CMF generated by a single filament of line mass M_line: (i) lognormal f_Mline(m) distribution (Eq. (2)) with (fiducial case, black curve); (ii) lognormal f_Mline(m) distribution (Eq. (2)) with fixed σ_Mline = 0.2 independent of M_line (blue curve); and (iii) broken power law, f_Mline(m)∝m⁶ for m <  M_BE, th, f_Mline(m) = constant for M_BE, th ≤ m <  M_BE, eff, f_Mline(m)∝m⁻⁴ for m >  M_BE, eff (red curve). For reference, the black dotted line displays the Salpeter-like power-law FLMF, dN/dlog , observed in the supercritical line mass regime (see Fig. 1), and the black dash-dotted line shows the typical mass distribution of CO clumps (Kramer et al. 1998).
