Comparison of the CMFs in Sh2-284 and the Galactic environments studied by Y. Cheng et al. (2018), M. Liu et al. (2018), T. J. O’Neill et al. (2021), and A. V. I. Kinman et al. (2025). Panel (a) shows the raw CMFs, while panel (b) shows the true CMFs, in which masses are corrected for flux recovery and the binned counts are corrected for number recovery. Dashed horizontal lines mark the level corresponding to one core per bin for each offset sequence, and open downward triangles mark zero-count bins. Solid lines show power-law fits obtained uniformly with the MLE method for panel (a) and the binned MLE method for panel (b), both starting from the bin centered at 2.51 M_⊙ with a lower edge of 1.995 M_⊙.
