Detailed Description

Correct for light deflection due to solar gravitation.

Function Documentation

void ae_relativity	(	double	p[],
		double	q[],
		double	o[]
	)

Correct for light deflection due to solar gravitation.

Note that this blows up if the object is very near (or is) the sun. Therefore, if the sun-object or sun-object distance is zero, no correction is made.

See AA page B37.

Parameters

p	The unit vector from observer to an object; this routine returns the corrected vector in this parameter.
q	The heliocentric ecliptic rectangular coordinates of the object.
o	The heliocentric ecliptic rectangular coordinates of the observer.
