Comparison between $M_{200}^{\mathrm{DR}3}$ and $M_{200}^{\mathrm{DR}4}$ for z_ob ∈ [0.1, 0.3) (left panels), z_ob ∈ [0.3, 0.45) (middle panels), and z_ob ∈ [0.45, 0.6) (right panels), applying the λ_ob^* cuts listed in Table 1 to the AMICO KiDS-1000 cluster sample. Top panels: Mean $M_{200}^{\mathrm{DR}3}$ against the mean $M_{200}^{\mathrm{DR}4}$. The error bars are derived by marginalising the mass estimates over all the free model parameter posteriors. The dashed black lines represent the 1:1 relation, while the red bands represent the 68% confidence of the linear model used for the fit. Bottom panels: Mass precision in KiDS-DR4 (magenta dots) and in KiDS-DR3 (orange crosses).
