Response of Lyman-α clustering to variations in cosmology and IGM physics according to FORESTFLOW. The top, middle, and bottom panels of the left column show the results for β, b_δ, and b_η, respectively, while those of the right column do so for the perpendicular modes of P_3D, the parallel modes of P_3D, and P_1D. Blue, orange, and red lines show the response of the previous quantities to a 5% increase in A_s, Ω_Mh², and σ_T, respectively, while green lines do so for a 1% increase in $\overline{F}$.
