Recovered signal in the mocks, when (grey shared area with 1σ and 2σ C.L. contours) and (orange 1σ shaded area) are computed from the MCMC samples, and when is directly estimated from the mocks (red data points with 1σ error bars). In this latter case, we take β = 0.84/2.13 = 0.39, as obtained from a previous fit of our model to the RSD-only measurements in the mocks. Both definitions are in agreement with the value of Ω_m/f computed using the Planck cosmology 2018 of the simulation (black dashed line). Measurements are performed with R₀ = 1.0 h⁻¹ Mpc, s_min = 17.8 h⁻¹ Mpc and no tapering.
