Comparison between the distribution of redshift (a), V-band magnitude (b), stellar mass (c), star formation rate (d), dust luminosity (e), and V-band optical depth in stellar birth clouds (f) for our whole sample of galaxies (gray filled histograms), and for the 601 galaxies expected to be detected at the 3σ level in the continuum in ALMA band 6 at 230 GHz, following the observational setup described in Table 2 (orange histograms, with numbers given on the right-hand y-axis). It is clear from these plots that the detected galaxies will be the most massive, star-forming, and dust-rich galaxies in the UDF.
