Best fit distributions of the BCS₄₀ sample per bolometric luminosity (left panel), Eddington ratio (central panel), and hydrogen column density (right panel) bin. The grey hatched and filled histograms are the distribution of unfitted and fitted sources. The blue and red filled histograms correspond to sources best fitted by clumpy disc+wind H17 models and torus models, respectively. The orange filled histograms are sources that have been equally fitted by clumpy disc+wind H17 models and torus models.
