Log-normal process spatial correlation power spectrum inferred in our reconstruction (solid line) as well as the imposed power spectrum of Lallement et al. (2018) (dashed line). The shaded area around the solid line indicates 1σ error bounds. The y-axis is in units of pc3. The functions can be interpreted as the a priori expected value of , where V is the volume on which the density ρ is defined, and F is the Fourier transform. The region between 0.0008/pc and 0.426/pc is almost power-law-like with a slope of 3.1, the spectral index of the power law.
