Normalized histograms of dust densities (panel a) and heat maps of voxel-wise correlations (panels b–d). The solid line corresponds to our reconstruction, while the dashed line is the reconstruction of Lallement et al. (2018) and the dash-dotted line is the reconstruction of Green et al. (2018). The other three plots are heat maps of voxel-wise correlations between reconstructed logarithmic dust densities, where the colors show bin counts. The black line in the heat maps is the identity function, corresponding to perfect correlation.
