ln_get_venus_equ_coords

public static void ln_get_venus_equ_coords(double JD,
                                           LnEquPosn position)

void ln_get_venus_equ_coords(double JD, LnEquPosn *position); \param JD Julian Day \param position Pointer to store position Calculates Venus'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_venus_helio_coords

public static void ln_get_venus_helio_coords(double JD,
                                             LnHelioPosn position)

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

ln_get_venus_earth_dist

public static double ln_get_venus_earth_dist(double JD)

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

ln_get_venus_solar_dist

public static double ln_get_venus_solar_dist(double JD)

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

ln_get_venus_magnitude

public static double ln_get_venus_magnitude(double JD)

double ln_get_venus_magnitude(double JD); \param JD Julian day \brief Calculate the visible magnitude of Venus \return Visible magnitude of venus Calculate the visible magnitude of Venus for the given julian day.

ln_get_venus_rst

public static int ln_get_venus_rst(double JD,
                                   LnLnlatPosn observer,
                                   LnRstTime rst)

double ln_get_venus_rst(double JD, LnLnlatPosn *observer, LnRstTime *rst); \param JD Julian day \param observer Observers position \param rst Pointer to store Rise, Set and Transit time in JD \return 0 for success, else 1 for circumpolar. Calculate the time the rise, set and transit (crosses the local meridian at upper culmination) time of Venus for the given Julian day. Note: this functions returns 1 if Venus is circumpolar, that is it remains the whole day either above or below the horizon.

ln_get_venus_sdiam

public static double ln_get_venus_sdiam(double JD)

double ln_get_venus_sdiam(double JD) \param JD Julian day \return Semidiameter in arc seconds Calculate the semidiameter of Venus in arc seconds for the given julian day.

ln_get_venus_rect_helio

public static void ln_get_venus_rect_helio(double JD,
                                           LnRectPosn position)

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