The synthesized CMF can be roughly divided into three segments, i.e., “1”, “2”, and “3”. Segment “2” is the transition part. “m1” and “m2” mark the mass range of the transition. Segment “3” is the real CMF of high-mass cores. The dashed red line is the observed CMF, for which observational biases prevent one from distinguishing the transition, resulting in a combined fit of three different segments with a shallower slope. Thus, the observed top-heavy CMF is an artifact.
