Despite our simplifying assumption to neglect spectral information, the resulting mass values estimated by the CNN exhibit small bias in comparison to the true masses of the simulated clusters (-0. 02 dex) and reproduce the cluster masses with low intrinsic scatter, 8% in our best fold and 12% averaging over all.
