Marginalized 1D probability distributions, P_1D, of b_g for different bias models. The continuous curves show P_1D for model 1 (constant bias) and model 2 (linearly growing bias), obtained from the joint NVSS gg and κg power spectrum analysis. All curves are normalized so that P_1D = 1 at the maximum. Different colors indicate the different N(z) models and match those used in Fig. 9. Dotted curves are drawn for comparison and show the P_1D from the NVSS cross-spectrum-only analysis. They are labeled CA to further distinguish them from those obtained from the joint analysis, labeled JA.
