Mass vs. size diagram for cores in W43, compared to the mass-size relation of critical Bonnor-Ebert spheres at T_dust = 23 Κ (black solid line). The core FWHMs are deconvolved from the beams, where the minimum deconvolved size corresponds to a half-beam angular diameter. In the main panel, the core sample is divided between prestellar core (represented by empty, blue and cyan symbols) and protostellar cores (filled, red and orange symbols), as well as between cores lying in W43-MM1 (diamonds) and in W43-MM2&MM3 (squares). Completeness levels in W43-MM1 and W43-MM2&MM3, 1.6 M_⊙ and 0.8 M_⊙ respectively, are represented by horizontal dashed lines. In the lateral panels are represented the marginal distributions of masses and FWHM sizes for the combined W43 region (W43-MM1 + W43-MM2&MM3), excluding cores below the common 1.6 M_⊙ completeness limit. Distributions of prestellar and protostellar core parameters are displayed in blue and red, respectively. The dashed lines show their median values.
