MOID

Name

moid

Purpose (one Line Only)

Compute the minimum orbit intersection distance between two orbits

Description

Calling Sequence

distance = moid(orb1,orb2)

Inputs

orb1 - Anonymous structure containing the first orbit. The following
tags must be defined in the structure:
semi - semi-major axis in AU
ecc - orbital eccentricity
inc - orbital inclination (radians)
node - Longitude of the ascending node (radians)
arg - Argument of perihelion (radians)
manom - mean anomoly (radians)
jdepoch - Julian Date of the epoch of the orbit
orb2 - Structure with the second orbit (same tags as the first orbit)
