compute

public void compute(double JD,
                    javax.vecmath.Tuple3d pos,
                    double precision)

Calculate the rectangular geocentric lunar coordinates to the inertial mean ecliptic and equinox of J2000. The geocentric coordinates returned are in units of UA. The truncation level of the series in radians for longitude and latitude and in km for distance. (Valid range 0 - 0.01, 0 being highest accuracy) This function is based upon the Lunar Solution ELP2000-82B by Michelle Chapront-Touze and Jean Chapront of the Bureau des Longitudes, Paris. ELP 2000-82B theory param JD Julian day, rect pos, precision
