Comparison between the redshift and the stellar mass obtained with the different SED runs. The comparison is performed for the HELM-1σ (top), the HELM-2σ (centre), and the HELM-3σ samples. Different colours indicate different SED fitting configurations: delayed SFH (pink circles), declined SFH (grey squares), double power-law SFH (olive hexagons), and delayed SFH with SMC dust attenuation law (cyan triangles). For the HELM-2σ we did not show, for clarity, three data points at z = 4.5 and z = 10.6, obtained with the delayed SFH with both reddening laws and the double power-law SFH, respectively.
