Toby has got a 'moon' point source that is fixed in the reference frame of the moon working in Gleam simulations. Next step in terms of fidelity would be to implement orbital parallax.
Toby has modified the flux package to allow an offset to be specified for the assignment of MC_SRC_ID values and Jim has implemented this as a hidden parameter for gtobssim. This allows some flexibility for creating distinct MC_SRC_ID values in models that are generated as separate runs for different components of the sky model.
