4D view of the dependance of the scaling relation coefficients on the simulation parameters. The marker size denotes the value of the scaling relation slope, and the marker color represents its dispersion. Both quantities are normalized with respect to the scaling relation of the fiducial model (central point). Top: Variation of the CR-M slope and scatter when varying Ω_m, σ₈, sampled on a linear grid. Bottom: Variation of the CR-M slope and scatter when varying A_SN1 and A_SN2, sampled on a logarithmic grid.
