  The studies of influence of spin on a photon's motion in a Schwartzschild
spacetime is continued. In the previous paper [13] the first order correction
to the geodesic motion is found for the first half of the photon world line.
The system of equations for the first order correction to the geodesic motion
is reduced to a non-uniform linear ordinary differential equation. The equation
obtained is solved by the standard method of integration of the Green function.
