NEOMOD: An advanced orbital distribution model for NEOs

Compute a probability of coming from a source. A version for kilometre-sized bodies. See examples.

Note: In this example, the orbits of Bennu and Ryugu are used. A user should select the corresponding CI-chondrite-like sources. A conclusion is that both come from Polana.
