Struct EquinoctialElements 

pub struct EquinoctialElements {
    pub a: f64,
    pub h: f64,
    pub k: f64,
    pub p: f64,
    pub q: f64,
    pub lambda: f64,
    pub retrograde: RetrogradeFactor,
}

Equinoctial elements (a, h, k, p, q, lambda), mean-longitude form.

The p and q fields are inclination components, not the semi-latus rectum.

Fields

a: f64

Semi-major axis (km), finite for all supported equinoctial conics.

h: f64

Eccentricity component e sin(varpi).

k: f64

Eccentricity component e cos(varpi).

p: f64

Inclination component tan(i/2)^I sin(raan).

q: f64

Inclination component tan(i/2)^I cos(raan).

lambda: f64

Mean longitude (rad).

retrograde: RetrogradeFactor

Retrograde factor used to build the components.
