Completeness levels of the -900 synthetic cores added on the background image of W43-MM2&MM3. The core content is 90% complete down to 0.8 ± 0.2 M_⊙ and 1.1 ± 0.2 M_⊙ for getsf and GExt2D, respectively. The error bars represent the ±1σ uncertainties for mass estimations across each bin (x-axis) and total of cores retrieved per bin (y-axis). Data points were interpolated using the Piecewise Cubic Hermite Interpolating Polynomial method. Blue and green points represent the full sample of cores detected by getsf and GExt2D, respectively, while red and orange points measure the bin completeness for cores that have mass measurements at worst larger or smaller than a factor of 2 compared to the truth table, thus excluding badly detected sources (see Appendix A and Table A.1 for complementary information).
