Semi-analytic problem definitions #48

Closed bprather closed 4 years ago

bprather commented 4 years ago

This adds a new problem demonstrating a small set of user-defined analytic emission profiles, as an example. The specific profiles included are from the EHT GRRT comparison (Gold et al 2020).

Marked [WIP] because it mysteriously doesn't match the published comparison numbers. I'm sure it's no big deal.

There. All fixed. We match every GRRT comparison problem to 2% MSE (turns out 4 != 4.063), and polarized transport of a completely unpolarized beam now works. Polarized flux matches ever so slightly better than it used to, now that it is measured at the camera instead of a step in front of it. Error handling has been improved so that error messages can include more context from callers, all the way out to main(). The thin disk problem has one fewer dead pixel.

I think this is ready, so opening for comments -- will merge upon review or early next week.
