Density plots for every object’s median probable model to reproduce the DIANA results (Sect. 3.2). Every panel shows the density structure in number densities of Hydrogen per cubic centimetre (colour bar at the top) for the objects noted in the panel. The upper and lower half of every plot depict the model from this study and DIANA, respectively. The radial axis is different for every object. The inner zones of Usco J1604-2130 in this work has a radial extent smaller than the radial resolution of the plots.
