Inferred SFR and sub-mm flux predictions from JWST and HST using three different SED codes. We show the inferred SFR in the first row, and sub-mm flux predictions in second and third rows. The three columns show, in order, the predictions for BAGPIPES, CIGALE and Prospector fits to the HST and JWST photometry of the red dropouts considered in this work (coloured points). For CIGALE and Prospector, we show only the highest likelihood solutions ΔL ∼ 1; while for BAGPIPES, we sample the full posterior as it is quite compact in parameter space. In the first row, we overplot the CSFRD multiplied by the field of view of the IRAC Dark Field (IDF), e.g. giving the SFR of a single galaxy contributing 100% to the CSFRD in that field. In the second and third row we overlay the different predictions with a horizontal gray bar the observed NOEMA fluxes and flux ratio. By comparing the observed NOEMA fluxes and flux ratios, we show clearly that the lower redshift solutions are strongly preferred. In the lower panels, the main trend in the NOEMA flux ratio is due to the dust graybody emission profile redshifting across the Polyfix sidebands. The outliers (CIGALE) and second track (Prospector) are due to high dust temperatures absent from the BAGPIPES fits.
