Contour plots of (Eq. (20)) for a few different values of p/σ with φ = 0 assuming a Jeffreys prior () and I₀/Σ = 100. The dots indicate the maximums of the distributions. Contour spacings are at intervals of 0.02. This figure is nearly the same as Fig. 1 with the roles of p and p₀ reversed. While for small values of p/σ and p₀/σ the plots appear identical, they are not. Their similarity diverges for larger values of signal-to-noise, as they must since p₀/σ has a maximum value while p/σ does not.
