Ratio of SFB spectrum with and without the physical effects of baryons in (ℓ,k) space for a wide and shallow survey (left, r₀ = 100   h^-1   Mpc) and a wide and deep survey (right, r₀ = 1400   h^-1   Mpc) using a Gaussian selection function in r. The baryonic wiggles are seen both in the radial (k) and the tangential (ℓ) directions, but as r₀ is increased, only radial wiggles – with increased amplitude – persist. This radialisation of the information is due to mode-cancelling along the line of sight for deep surveys.
