Completeness level of the ALMA continuum map at 3 mm as a function of mass. The KDE shown in red indicates the detection probability of the cores in the noise-free regions. The KDE illustrated in green represents the detection probability for the cores located at the vicinity of bright sources. A completeness level of 90% is obtained for cores with masses > 1.5 M_⊙ and > 3 M_⊙ for the regions with a lower noise (0.3 mJy beam⁻¹) and a higher noise (0.9 mJy beam⁻¹) respectively.These completeness limits are marked with vertical dashed and dotted lines for the noise-free and noisy regions, respectively.
