Stellar mass as a function of photometric redshift for the 18 ALMA galaxies. The green rectangles represent the expected values of the characteristic mass ℳ_* and their uncertainties obtained by fitting the mass function of SFGs with a Schechter function in the redshift ranges 0.2–0.5, 0.5–0.8, 0.8–1.1, 1.1–1.5, 1.5–2.0, 2.0–2.5, 2.5–3.0, 3.0–3.5, and 3.5–4.0 (Davidzon et al. 2017). The source IDs are labelled next to the corresponding symbols.
