Hi all. I was testing assist for generating asteroid ephems faster than I could ordinarily download from Horizons. This isn't precisely relevant for what I'm doing (I only need positions to medium precision) but there's a particularly unusual Centaur, 2004 TZ387, that made a close approach to Jupiter in 2015, to which an accurate orbit fit requires considering both the non-spherical Jupiter terms (mostly J2, I don't think it has significant odd harmonics) and the Galilean moons during its flyby. This actually caused problems for the MPC's default orbit integrator leading to spuriously high nongrav terms.
As a feature request, could there be an option to turn on those forces if suitable data is provided (e.g. jup310.bsp)?
