pint.models

Pulsar timing models and tools for working with them.

The primary object for representing a timing model is TimingModel. This contains a collection of components (subclasses of Component), each of which should have a collection of parameters (subclasses of Parameter). These parameters carry values uncertainties and units and can be “frozen” or “free” to indicate whether fitters (subclasses of Fitter) should be allowed to modify them. Normally timing models are created using get_model() but it is possible to construct and modify them as python objects.

Binary models are implemented as Components, but they have somewhat special handling; they are implemented by deriving from PSR_BINARY, which provides some of the infrastructure needed to implement them conveniently.
