Function astro::planet::ecl_coords_to_FK5 [−] [src]

pub fn ecl_coords_to_FK5(JD: f64, ecl_long: f64, ecl_lat: f64) -> (f64, f64)

Computes a planet's geocentric ecliptic coordinates converted to the FK5 system

Returns

(ecl_long_FK5, ecl_lat_FK5)

ecl_long_FK5: Ecliptic longitude of the planet, converted to the FK5 system | in radians
ecl_lat_FK5 : Ecliptic latitude of the planet, converted to the FK5 system | in radians

Arguments

JD : Julian (Ephemeris) day
ecl_long: Ecliptic longitude of the planet on JD referred to the mean equinox of the date | in radians
ecl_lat : Ecliptic latitude of the planet on JD, referred to the mean equinox of the date | in radians
