Magnitude of the tangential velocity normalised to the magnitude of the total velocity ($|V_{\theta }^{\mathrm{sat}}|/|V^{\mathrm{sat}}|$, left panel) and the scalar product between the normalised angular momentum of the disc of the host central galaxy (${\widehat{\text{S}}}^{\mathrm{cen}}$) and the normalised orbital angular momentum of each satellite (${\widehat{\text{L}}}^{\mathrm{sat}}$, right panel). Both quantities are expressed as a function of μ_r^cen for the same stellar mass ranges as in Fig. 7. The solid lines correspond to the medians, and the shadowed region encloses the median bootstrap error.
