Parameters

Pos1  Double

Position vector of observed object, with respect to origin at observer (or the geocenter), components in AU.

PosObs  Double

Position vector of observer (or the geocenter), with respect to origin at solar system barycenter, components in AU.

PosBody  Double

Position vector of gravitating body, with respect to origin at solar system barycenter, components in AU.

RMass  Double

Reciprocal mass of gravitating body in solar mass units, that is, Sun mass / body mass.

Pos2  Double

Position vector of observed object, with respect to origin at observer (or the geocenter), corrected for gravitational deflection, components in AU.
