Pearson coefficient of the inferred and true density field as a function of the position across lines of sight. The dashed lines indicate the positions of the lines of sight. The Pearson coefficient is > 0.9 at any location in the density field. This, combined with Fig. 8 showing that the algorithm recovers the correct amplitudes, indicates that the algorithm can interpolate the information between lines of sight and correctly recover the structures in unobserved regions.
