Comparison between the marginalised constraints on the linear bias parameter b₁ and the shot-noise parameter α_P, 1 obtained at fixed cosmology, and the fiducial values listed in Table 4 obtained using only the large scale-limit of Eq. (45). The first two and last two rows show results for the Model 1 and Model 3 HOD samples, respectively. In both cases, the upper panels show constraints on the linear bias b₁, while the bottom ones show constraints on the constant shot-noise parameter α_P, 1. Different colours correspond to different assumptions on the total number of free bias parameters, as shown in the legend. Star symbols highlight the position of the maximum-likelihood for the case with all bias parameters free to vary. Dashed grey lines and shaded bands mark the fiducial value and 1σ confidence interval from Table 4.
