Functions
template<typename units >
units::realT	mx::astro::orbitPeriod (typename units::realT m1, typename units::realT m2, typename units::realT a)
	Calculate the period of an orbit, given the masses and semi-major axis.
template<typename units >
units::realT	mx::astro::orbitSemiMaj (typename units::realT m1, typename units::realT m2, typename units::realT P)
	Calculate the semi-major axis of an orbit, given the masses and Period, using SI units.
template<typename realT >
realT	mx::astro::orbitMeanAnol (realT t, realT t0, realT P)
	Calculate the mean anomaly at time t, given the time of pericenter passage t0 and period P.
template<typename realT >
long	mx::astro::orbitElements (realT &r, realT &f, realT E, realT D, realT e, realT M, realT a, realT tol=KEPLER_TOL, long itmax=KEPLER_ITMAX)
	Calculate the separation and true anomaly for an orbit at the specified mean anomaly.
template<typename realT >
realT	mx::astro::orbitPhaseCosine (realT f, realT w, realT inc)
	Get the orbital phase at true anomaly f. Calculates the cos(alfa) where alfa is the orbital phase.

	Calculate the radial velocity of an orbiting body inclined relative to an observer.
template<typename vectorT , typename realT >
int	mx::astro::orbitCartesianWork (vectorT *x, vectorT *y, vectorT *z, vectorT *r, vectorT *rProj, vectorT *f, vectorT *cos_alf, vectorT *phi, const vectorT &t, const size_t N, realT a, realT P, realT e, realT t0, realT i, realT w, realT W)
	Calculate various quantities of an orbit given the keplerian elements and a vector of times.
template<typename vectorT , typename arithT >
int	mx::astro::orbitCartesian2DPhi (vectorT &x, vectorT &y, vectorT &r, vectorT &rProj, vectorT &phi, const vectorT &t, const size_t N, arithT a, arithT P, arithT e, arithT t0, arithT i, arithT w, arithT W)
