Normalised (i.e. independently for each histogram such that the area under the histogram is 1) histograms showing in blue the summed posterior distributions of the BLR parameters from the best fits to all the z ∼ 2 targets. The panels correspond to (a) the radial distribution of BLR clouds, (b) the inclination angle, (c) the opening angle, with the minimum and maximum values defining the thin disc and spherical shape, respectively, (d) the ratio between the minimum and mean Hα BLR radius, and (e) the mean (emissivity) Hα BLR radius.
