Artist view adapted from the 3D simulations of Romanova et al. (2013) of accretion funnel flows along an inclined magnetosphere. Those describe the four cases invoked in Appendix A to explain the different dips shapes. The top left panel represents an accretion flow covering a wide range in longitude (case 1), the top right panel shows a wide accretion flow split in several arms (case 2), the bottom left panel represents an accretion flow narrower than cases 1 and 2 and split in two different arms (case 3), and the bottom right panel shows a typical accretion flow of one narrow stream (case 4).
