Validation of stellar masses as a function of redshift measured using photometry in the bandpasses included by the present DAWN survey PL catalogues. Each panel shows the difference in stellar mass measured using the COSMOS2020 catalogue (Weaver et al. 2022) when using only the present DAWN bandpasses (‘PL’) and all forty (‘All’) of the original bandpasses of COSMOS2020. The medians are indicated by the red lines, and the shaded envelopes enclose 68% of the sources corresponding to 1σ.
