Halo masses in the high-resolution Gadget simulation compared to those in the low-resolution BORG simulation. We note that M_HR, 12 is the 100 kpc filtered mass (blue) or M_200c value (orange) in the Gadget resimulation in units of 1 × 10¹² M_⊙, while M_LR, 12 indicates the corresponding quantities for the BORG simulation. σ indicates the scatter around the power-law fits to the relations given in the figure legend.
