Example of SED for a source at z = 6.78 in the 9 <  log(M_⋆^{no − IR}/M_⊙)< 10 stellar mass bin. The open black squares are the fluxes from HST and JWST and the blue line is the best fit model obtained fitting these data points. The filled black square indicates the ALMA measurement from stacks obtained in the same stellar mass bin, and the red line indicates the best fit model obtained when adding this IR constraint to the SED fitting. Parameters obtained from the two fits are indicated using the same colours. As an indication, the best SEDs obtained from the rest of the galaxies in the same stellar mass bin are shown in light grey.
