Complementary cumulative distribution function (CCDF) plot and the linear fitting of the synthesized CMFs (in cyan) for W43-MM1 by setting f_b = 1 and ϵ_core = 0.2. (a)–(c) The cases of m_max = 150 M_⊙, half the original number of stars (N_star/2) and twice the original number of stars (N_star * 2), respectively; (d) The case in which ϵ_core decreases with decreasing core mass. ϵ_core was randomly selected from the range (0.2, 0.4); (e) The case in which ϵ_core increases with decreasing core mass. ϵ_core was randomly selected from the range (0.2, 0.4); (f) Same as panel e, but ϵ_core is in the range (0.1, 0.3). All selected ϵ_core in panels d, e, and f are sorted in descending or ascending order. All CCDFs (both observed and synthesized) were normalized to 1 at the mass completeness level marked by the left vertical dashed line.
