Example of output halo mass PDFs from DfL from the TNG model applied to the TNG testing data at z = 1. The shaded histograms show the probability distributions of the halo mass for a randomly selected low-, intermediate-, and high-mass group (colored blue, green, and red, respectively). The true halo mass from the simulation is indicated by a vertical solid line, with the DfL geometric mean output from the pipeline indicated by a vertical dashed line. The PDF can be used to extract the mode, linear mean, or any other indicator for the best mass prediction for M₂₀₀, as desired.
