Abstract:
The integrals of photon motion in the Kerr spacetimes are given in terms of the emission angles related to emitters moving along the circular geodesic orbits. The local frames of the circular geodesic emitters are given in relation to the locally nonrotating frames and local directional angles of the escape cones are given in terms of the motion constants of photons.
