Multipoles | Q_m | ² | for a central peak with height ν = 2 to 4 as labelled in a Gaussian random field with power spectrum P(k) ∝ k⁰ smoothed with a Gaussian filter and on the annulus at a distance r = 0.1 R (top left-hand panel), R (top right), and 2 R (bottom left). The dashed line corresponds to the random case in which we do not impose a central peak. The bottom right-hand panel shows the ratio of those multipoles to the random case for r = R.
