Not-to-scale sketch of the adopted axisymmetric geometry shown in the poloidal plane. The gray half-circle denotes the stellar photosphere, the dark rectangle represents the disk, which is assumed to be opaque and to extend to the innermost magnetic field line. The dotted lines represent the magnetosphere and its purely dipolar field lines, and the dash-dotted lines are parabolic trajectories that represent the disk wind streamlines. The inner and outer magnetospheric field lines intersect the disk at r_mi and r_mo, respectively, and the ring between r_di and r_do is the region where the disk wind is ejected. The inclination from the z-axis is given by θ, and ϑ₀ is the disk-wind launching angle.
