Dependence of J_R,w with the structure and kinematic parameters of the simulations: radial scale-length (upper panel) and vertical scalelength (lower panel). Coloured markers refer to simulation families: AURIGA (blue circles), ILLUSTRIS (orange triangles), NEWHORIZON (red diamond), NEXUS (purple triangles), and NIHAO-UHD (green square). Black markers denote measurements for the Milky Way reported in the literature (see main text). Open markers denote outliers excluded from the linear fit (dashed line) by the σ-clipping algorithm.
