Many thanks John, this looks good.

Looking through this, I do wonder whether we need more tests of this model. We only have a single test but there are lots of possible decay modes and two different possible values of the whichfit parameter and so we should probably try to cover all of those possibilities. Perhaps we can ask the authors of the model to help out with those. If you agree, perhaps you could make a task for this so we don't forget about it? This revision can be landed as-is, however.

This revision is now accepted and ready to land.Dec 16 2022, 4:51 PM

Add tests for Bc -> J/psi pi pi0 & psi(2S) pi BC_VHAD modes.

I have added some example tests for this, and have also created a task where we could add more tests for other models in the future: https://phab.hepforge.org/T205
