Measurements of shape bias parameters in the Planck simulation as a function of peak-significance ν = δ_c/σ(M, z). All measurements, regardless of redshift, seem to follow a common trend with ν. Solid black lines show the fits performed to approximate these common relations. These fitting functions are exceptionally simple – linear for c_K and c_K⊗K and quadratic for c_δK – and provide good descriptions of the measured relations.
