Distribution of dynamical mass enclosed within the projected half-light radius (R_h) of dispersion-supported galaxies for each suite of simulations. Blue and orange histograms show, respectively, the distributions of NIHAO and AURIGA galaxy projections with 100 bins, while the dashed black line histogram shows their distribution at 30 bins, which we made equal in the two suites by dropping excessive projections from each dataset. The dashed grey lines show the distribution of FIRE galaxy projections inside the mass range covered by NIHAO and AURIGA.
