Model vs. measured NVSS κg (top panels) and gg (bottom panels) angular power spectra. The measured cross-spectra (top panels) are the same as in the previous plots. Error bars represent 1σ Gaussian uncertainties. The curves show model predictions. They are surrounded by shaded areas that represent the 2σ uncertainty interval of the best fitting b_g values. The green color in the left panels indicates models that adopt the T-RECS N(z) prescription. The purple color flags the adoption of the S³ model in the right panels. Continuous and dashed lines are used for bias model 1 and model 2, respectively. All best fitting b_g values are listed in Table 8.
