Values of the BAOlet coefficients W_R,s expected at the positions of large initial point-like perturbations, as a function of the BAOlet parameters (R,s). The bottom panel shows the result using a standard ΛCDM transfer function, while the top panel shows the result using a transfer function with the BAO wiggles edited out (Eisenstein & Hu 1998). The normalisation is arbitrary. The contours are drawn in steps of 1000 for W_R,s < 0 (dotted), W_R,s = 0 (solid), and W_R,s > 0 (dashed). The map attains a maximum at R = 110   h^-1   Mpc, s = 22   h^-1   Mpc.
