int GravityEngine2.GravityJ2.status

static

Apply the addition force change due to oblate gravity modeled by a J2 dipole term.

The equation for the perturbing force is taken from Gravity (Poisson) (3.90) p166

This routine is called for each massive (i,j) pair. Those that have a "from body" with a non-zero J2 will apply the non-spherical perturbing force to the other.

There really should be an equal and opposite force on the source of the J2 force but since this is most often used for a planet force on a satellite, this is neglected since it's so small.
