Notes. Azimuths are angles in degrees counted from the line joining the two stars, positive in the direction of disk rotation. MWD and MRG are the mass of the WD and RG, i and a the orbital inclination and separation, and RRG is the radius of the Roche lobe. Next, ri and Vi are the closest distance to the WD and the velocity at that point of the accretion stream on a fly-by trajectory around the WD (thus, ri is the minimum radius of the disk to intercept the stream, at ∼159° azimuth). Then, rc, θc, and Vc are the disk’s circularization radius and for the impacting stream the corresponding azimuth and velocity. ro, θo, and Vo are the corresponding values for the outer disk radius in the ro = 2 × rc approximation. Finally, the last column reports about eclipsing of the hot spot by the RG (“grz” stands for the grazing condition).
