ln_get_equ_prec

public static void ln_get_equ_prec(LnEquPosn mean_position,
                                   double JD,
                                   LnEquPosn position)

void ln_get_equ_prec(struct ln_equ_posn *mean_position, double JD, struct ln_equ_posn *position) \param mean_position Mean object position \param JD Julian day \param position Pointer to store new object position. Calculate equatorial coordinates with the effects of precession for a given Julian Day. Uses mean equatorial coordinates and is only for initial epoch J2000.0 Equ 20.3, 20.4 pg 126

ln_get_equ_prec2

public static void ln_get_equ_prec2(LnEquPosn mean_position,
                                    double fromJD,
                                    double toJD,
                                    LnEquPosn position)

void ln_get_equ_prec2(struct ln_equ_posn *mean_position, double fromJD, double toJD, struct ln_equ_posn *position); \param mean_position Mean object position \param fromJD Julian day (start) \param toJD Julian day (end) \param position Pointer to store new object position. Calculate the effects of precession on equatorial coordinates, between arbitary Jxxxx epochs. Use fromJD and toJD parameters to specify required Jxxxx epochs. Equ 20.2, 20.4 pg 126

ln_get_ecl_prec

public static void ln_get_ecl_prec(LnLnlatPosn mean_position,
                                   double JD,
                                   LnLnlatPosn position)

void ln_get_ecl_prec(struct ln_lnlat_posn *mean_position, double JD, struct ln_lnlat_posn *position) \param mean_position Mean object position \param JD Julian day \param position Pointer to store new object position. Calculate ecliptical coordinates with the effects of precession for a given Julian Day. Uses mean ecliptical coordinates and is only for initial epoch J2000.0 \todo To be implemented.
