ln_get_saturn_equ_coords

public static void ln_get_saturn_equ_coords(double JD,
                                            LnEquPosn position)

void ln_get_saturn_equ_coords(double JD, LnEquPosn position); \param JD julian Day \param position Pointer to store position Calculates Saturn's equatorial position for given julian day. This function includes calculations for planetary aberration and refers to the FK5 reference frame. To get the complete equatorial coordinates, corrections for nutation have to be applied. The position returned is accurate to within 0.1 arcsecs..

ln_get_saturn_helio_coords

public static void ln_get_saturn_helio_coords(double JD,
                                              LnHelioPosn position)

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

ln_get_saturn_earth_dist

public static double ln_get_saturn_earth_dist(double JD)

double ln_get_saturn_earth_dist(double JD); \param JD Julian day \brief Calculate the distance between Saturn and the Earth in AU \return Distance in AU Calculates the distance in AU between the Earth and Saturn for the given julian day.

ln_get_saturn_solar_dist

public static double ln_get_saturn_solar_dist(double JD)

double ln_get_saturn_solar_dist(double JD); \param JD Julian day \brief Calculate the distance between Saturn and the Sun in AU \return Distance in AU Calculates the distance in AU between the Sun and Saturn for the given julian day.

ln_get_saturn_magnitude

public static double ln_get_saturn_magnitude(double JD)

double ln_get_saturn_magnitude(double JD); \param JD Julian day \brief Calculate the visible magnitude of Saturn \return Visisble magnitude of saturn \todo Calculate rings brightness Calculate the visible magnitude of Saturn for the given julian day.

ln_get_saturn_rst

public static int ln_get_saturn_rst(double JD,
                                    LnLnlatPosn observer,

public static double ln_get_saturn_pol_sdiam(double JD)

double ln_get_saturn_pol_sdiam(double JD) \param JD Julian day \return Semidiameter in arc seconds \todo Use Saturnicentric lat of Earth Calculate the polar semidiameter of Saturn in arc seconds for the given julian day.

ln_get_saturn_rect_helio

public static void ln_get_saturn_rect_helio(double JD,
                                            LnRectPosn position)

void ln_get_saturn_rect_helio(double JD, LnRectPosn position) \param JD Julian day. \param position pointer to return position Calculate Saturns rectangular heliocentric coordinates for the given Julian day. Coordinates are in AU.
