Zero lag annulus correlation function 
in units of 
for a central peak with height 
and eigenvalues 
and 
in rz for a Gaussian random field with power spectrum P(k) ∝ k0 smoothed with a Gaussian filter (similar to Fig. 3 when the two points on the annulus are the same). The separation r is given in units of the smoothing length.
