Caption

Graph showing the time-dependent geometry of a pulsar. Dark matter cosine as viewed by the observer. The Z axis goes from the observer to the pulsar (dot on the left). The point of closest approach is a distance D along the X axis. The Y coordinate is upward along the projected speed of the mass concentration. The displacement along Y is taken as V t. The mass concentration is in the plane at (D,Vt).
