velocity DF

Open joshspeagle opened this issue 5 years ago • 0 comments

Thanks to the efforts of @gusbeane, we now have an implementation of a velocity distribution function based on galpy and jeans modelling!

The goal with this issue is to track the steps needed to get this up and running:

  • [ ] Merge the velocity DF branch into the main branch.
  • [ ] Reorganize functions so that they are internally consistent (total mass vs f_at_solar) and track input arguments.
  • [ ] Pre-compute the grid of first+second moments for each component of the disk and each component of the observed quantities over the defaults.
  • [ ] Convert the corresponding outputs to observational quantities (RV, PM_RA, PM_DEC).
  • [ ] Integrate this into the BruteForce fitting evaluation by allowing users to pass proper motions.
