Geometry of the projected orbit which is indicated by green ellipse and lies in X − Y plane. The orbit is elongated along the Y−axis. The Z−axis is perpendicular to X − Y plane, i.e., the plane of the orbit. The viewing angle θobs and i are the polar coordinate of the line-of sight. The inclination angle i is measured from the Z−axis. The angle θobs is measured from the line θ = 0. The azimuthal angle ψ is the angle in the plane of the orbit and it’s defined to be zero at the line of nodes.
