Function astro::lunar::geocent_ecl_pos

pub fn geocent_ecl_pos(JD: f64) -> (EclPoint, f64)

Computes the geocentric ecliptic position of the Moon, referred to the mean equinox of the date

Returns

(moon_ecl_point, rad_vec)

• moon_ecl_point: Ecliptic point of the Moon | in radians
• rad_vec: Moon-Earth distance | in kilometers

This function uses the partial Chapront ELP-2000/82 lunar theory, so the accruacy of:

• moon_ecl_point.long: is 10 arcseconds
• moon_ecl_point.lat: is 4 arcseconds

Arguments

• JD: Julian (Ephemeris) day
