Left: Validation of stellar masses predicted from a random forest regressor trained on photometry from the COSMOS2020 in the DAWN PL filter set. The y-axis shows the difference in stellar mass between the random-forest-predicted values, after scattering the photometry within the photometric errors, and the official Weaver et al. (2022) stellar masses measured with LePHARE and greater than 40 photometric bands. The x-axis shows the official Weaver et al. (2022) stellar masses. Galaxies are selected for this comparison using the criteria described in Sect. 3.1. Right: Comparison of stellar masses predicted from DAWN PL photometry using the random forest trained on COSMOS2020 as described above. The y-axis shows the difference in stellar mass between the random-forest-predicted values from DAWN PL and the stellar masses measured from LePHARE using the same photometry provided by EC-Z25. The x-axis shows the LePHARE stellar mass. Galaxies selected for this validation also satisfy the requirements of Sect. 3.1. Shading corresponds to logarithmic density.
