I have a question. I know VSOP87 is used for the planet modules, and ELP2000 for the Moon. Do you know what theories are used for the other modules (the minor planets, other moons, etc) ? This question is for versions up to 2016. I'm wanting to recreate ephems for these, but I don't know if they are just 2-body models or using JPL Horizon or DE ephems. Thanks.
