Well it's mainly "utility functions", ie I need to define a (keplerian) orbit. Which is normally done by giving
semi-major axis, eccentricity, inclination, argument periapsis and longitude ascending node. However there are lots
of "variations": ie for parabolic orbits the semi major axis is replaced by semi latus rectum. Or you can just use
state variables at a point (position + velocity in 3 dimensions). Or you could replace the semi major axis +
eccentricity by peri + apo apsis.
