Power spectrum prior used for our astronomical visibilities (orange). The faint black curves are the true calculated power spectrum for all baselines in one of our simulations. The blue curve shows the median power spectrum and the black dashed line shows the maximum expected fringe rate of the longest baseline in our simulation. The parameters for the example priors shown are P₀ = 10⁷ Jy², η₀ = 1 mHz. and γ = 5, 2, and 1.
