Notes. The columns “physical” refer to results with a physical model (Sect. 7.1), “generic” columns list the results with generic fitting functions (Sect. 7.2). Quoted values are for the errors in the domain k ∈ [0.05, 10] h Mpc−1 for b(k) and k ∈ [0.3, 10] h Mpc−1 for r(k). The values Δb and Δr inside the brackets are the most significant deviations between reconstructed and true biasing functions. Values in the last rows with ⟨σb,r ⟩ (or ⟨Δb,r ⟩) are averages and dispersions for σb and σr (or Δb and Δr) of all samples in the same redshift bin.
