Schematic illustration of the emission and scattering geometry invoked to explain the polarization properties of E1821+643. The broad-line emission originates in two components of gas characterized by different bulk velocities and velocity dispersions (R1 and R2). Both velocity vectors are aligned with the symmetry axis of the scattering region and the observer's line of sight is inclined at angle α to this axis. The scattering is far-field in the sense that the emission regions effectively constitute a single point source as viewed from the scattering region.
