Library to compute distance between elliptic orbits (MOID)
This C++ library allows to compute the Minimal Orbital Intersection Distance (MOID) between two elliptic confocal orbits using the method by Kholshevnikov & Vassiliev (1999), Cel. Mech. Dyn. Astr., 75, 75. The implementation of the method is described in (Baluev & Mikryukov 2019), Astronomy & Computing, 27, 11.
It employs numeric error control and deals carefully with nearly degenerate cases (like almost circular and almost coplanar orbits).
Library also includes auxiliary functions...
