Fields

a: f64

Semimajor axis in astronomical units (AU).

l: f64

Mean longitude at epoch.

k: f64

`e * lper.cos()``, where e is the eccentricity and lper is the longitude of the perihelion.

h: f64

`e * lper.sin()``, where e is the eccentricity and lper is the longitude of the perihelion (ϖ).

q: f64

(i/2.0).sin() * lan.cos() where i is inclination and *lan is the longitude of the ascending node (Ω).

p: f64

(i/2.0).sin() * lan.sin() where i is inclination and *lan is the longitude of the ascending node (Ω).
