Dust mass function of the N2GN sources (red symbols). Only the mass bins containing at least two galaxies and with a completeness ≥50% are plotted. Uncertainties take into account ΔM_dust, including SED fitting parameters sampling and Δz contributions, and Poisson errors. Left panel: comparison to literature results by Pozzi et al. (2020, blue filled squares and long-dashed line) and Traina et al. (2024a, light blue triangles and short-dashed lines, fiducial results in the 2.0 < z ≤ 2.5, 3.5 < z ≤ 4.5 and 4.5 < z ≤ 6.0 redshift bins). The blue dotted lines are the same Pozzi et al. (2020) DMF, evolved to z = 2.0 and 3.3 (see Sect. 6.2). Right panel: results of the STY analysis. The green solid lines and shaded areas are the result of the STY parametric analysis: most probable model (solid lines) and 1σ uncertainty (shaded areas). The dashed green lines represent the 1.6 < z ≤ 2.4 result, repeated in the other two redshift bins for comparison.
