astro::ecl_frm_eq!

macro_rules! ecl_frm_eq {
    ($asc: expr, $dec: expr, $oblq_eclip: expr) => { ... };
}

Computes ecliptic coordinates from equatorial coordinates

Returns

(ecl_long, ecl_lat)

• ecl_long: Ecliptic longitude | in radians
• ecl_lat: Ecliptic latitude | in radians

Arguments

• $asc: Right ascension | in radians
• $dec: Declination | in radians
• $oblq_eclip: If $asc and $dec are corrected for nutation, then true obliquity. If not, then mean obliquity. | in radians
