class peebee.models.GalaPotential(pot, **kwargs)

Bases: Model

Wrapper for Gala potential objects.

Allows use of any instantiated Gala potential object within the peebee modeling framework. Requires the Gala package to be installed.

Methods Summary

accel(x, y, z, **kwargs)	Compute acceleration using Gala potential.
set_params(params[, ignore_name_check])	Set all model parameters from a dictionary.
update_params(params)	Update a subset of model parameters by name.
