Halo mass versus total mass within R₁. We show the δM₂₀₀ and δM_T(< R₁) residuals from the log M₂₀₀ − log M_⋆ versus log M_T(< R₁) − log M_⋆ relations, for galaxies with M_⋆ > 10⁹ M_⊙. AURIGA, HESTIA and NIHAO galaxies are shown with orange dots, blue crosses and green squares. Every galaxy is coloured by the concentration of its halo, with darker colours referring to higher concentration and vice versa. Every suite is upper and lower limited by a halo concentration value of 40 and 7, respectively. Best-fitting is shown following the same colour code used for each simulation suite, along with their Spearman rank correlation coefficients. We also show, within dashed grey, the 1:1 line for reference.
