Posteriors of the joint fit of the clustering with non-linear bias and the alignment with TATT for different values of Π_max, for the 1 Gpc box (in blue) and the 2.8 Gpc box (in red). The darker the shade of blue/red, the higher the value of Π_max. Decreasing Π_max increases the S/N, and if there are sufficient statistics, different Π_max values give consistent answers. The degeneracy between b₁ and b₂ is exacerbated by smaller statistical power, and may even lead to biased results if too low a value of Π_max is chosen.
