Now we
start the photon 45 degress off the equatorial plane,
=
,
still with direction radially inwards,
= (-0.5,0,0).
We integrate the geodesic equation in 300 steps,
using a step size = 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.
