a/M varies (2nd example)

  Now we start the photon 45 degress off the equatorial plane, tex2html_wrap_inline292 = tex2html_wrap_inline1137 , still with direction radially inwards, tex2html_wrap_inline296 = (-0.5,0,0).

We integrate the geodesic equation in 300 steps, using a step size tex2html_wrap_inline300 = 0.20

In this movie, we again vary the rotation parameter a/M from 0.00 (no rotation) to 1.00 (the most extreme rotation possible).

The IDL script is mf_02.
