cogwheel.gw_prior.combined

Define some commonly used priors for the full set of parameters, for convenience.

Prior classes defined here can be used for parameter estimation and are registered in a dictionary prior_registry.

Note on registered prior class names:

• LVC*, IAS* and Volumetric* priors differ on the distribution of component spins: LVC is isotropic and uniform in magnitude, IAS is uniform in the effective spin, and Volumetric is isotropic and uniform in the magnitude cubed.

• Intrinsic* priors are for the intrinsic parameters only, these priors may be paired with a likelihood that marginalizes over extrinsic parameters.

• Cartesian* priors try to avoid polar coordinates for the inplane spin components, these are better suited for samplers that don’t implement periodic parameters.
