Notes. (2) Ratio of the local core surface density measured for the five most massive cores to that averaged for all cores in each W43-MM2&MM3 subregion. (3) and (4) Core mass segregation ratio computed from Eq. (7) over the NMST range. (5) Core mass segregation level (see Sect. 3.3); three regimes for the MM2 subregion corresponding to the plateaus observed in Fig. 8a.
