Aspherical excess of the flows parametrised by the asphericity parameter ζ at 1.2r_vir (left) and 2.0r_vir (right) for the inflowing and outflowing components, respectively. The violins show the vertical distribution, while the black horizontal lines show the median for each bin. The bin present in both simulations (Box2b/hr and Box4/uhr) is plotted twice to indicate the transition in resolution.
