Eilers (MIT) started the day with a discussion of how, specifically, to modify our paper given Friday's discussion of potential perturbations and realism in steady-state dynamical models. It is obvious that a mixture of rigidly rotating fixed patterns can mock up what we want for our potential perturbation, but then computing each of these is not simple, since resonances occur. So what to do to mock up something that is more like a continuous integral over an infinite family such perturbations, which would have no such pathologies? We have various hacks in mind, but there are trade-offs between having more complete math and having more discursive discussion about the math. I usually prefer the latter. But if part of our audience is graduate students trying to reproduce the result, it might make sense to get more math in there.
