Chapter 31 Pg 206-207 Equ 31.1 31.2 , 31.3 using VSOP 87

ln_get_earth_solar_dist

public static double ln_get_earth_solar_dist(double JD)

double ln_get_earth_solar_dist(double JD); \param JD Julian day. \return Distance in AU Calculates the distance in AU between the Sun and Earth for the given julian day.

ln_get_earth_centre_dist

public void ln_get_earth_centre_dist(float height,
                                     double latitude,
                                     DoubleRef p_sin_o,
                                     DoubleRef p_cos_o)

void ln_get_earth_centre_dist (float height, double latitude, double *p_sin_o, double *p_cos_o); \param height Height above sea level in metres. \param latitude latitude in degrees. \param p_sin_o Pointer to hold p_sin_o \param p_cos_o Pointer to hold p_cos_o Calculate the quantities "p sin o" and "p cos o" needed in calculations for diurnal parallaxes, eclipses and occultations given the observers height in metres above sea level and there latitude in degrees.

ln_get_earth_rect_helio

public static void ln_get_earth_rect_helio(double JD,
                                           LnRectPosn position)

void ln_get_earth_rect_helio(double JD, struct ln_rect_posn *position) \param JD Julian day. \param position pointer to return position Calculate the Earths rectangular heliocentric coordinates for the given Julian day. Coordinates are in AU.
