Subtracting the primary's RV (which already includes reflex motion from
every companion) accounts for the Jacobi offset of interior companions,
so the explicit RV perturbation term counted it twice. Remove it, and
scale each companion's barycentric RV by the mass interior to its orbit
rather than the stellar mass alone.
