Struct vsop87::SphericalCoordinates

pub struct SphericalCoordinates { /* fields omitted */ }

Structure representing spherical coordinates of a body.

Methods

impl SphericalCoordinates

fn longitude(&self) -> f64

Gets the ecliptic longitude of the body, in radians.

This value represents the angular distance of an object along the ecliptic plane from the primary direction. In the case of heliocentric coordinates, it represents the l parameter, in geocentric coordinates, represents the λ parameter.

fn latitude(&self) -> f64

Gets the ecliptic latitude of the body, in radians.

This value represents the angular distance of an object from the ecliptic towards the north ecliptic pole. In the case of heliocentric coordinates, it represents the b parameter, in geocentric coordinates, represents the β parameter.

fn distance(&self) -> f64

Gets the distance to the center of mass, in astronomical units (AU).

In the case of heliocentric coordinates, it represents the r parameter, in geocentric coordinates, represents the Δ parameter.
