Supported models
================

Peculiar-velocity models
------------------------

These models work in units of :math:`h^{-1}\,\mathrm{Mpc}` and can be analysed
jointly via :class:`~candel.model.base_pv.JointPVModel` with user-specified
shared parameters.

- **Tully--Fisher relation** (:class:`~candel.model.model_PV_TFR.TFRModel`):
  2MTF, SFI++, CF4-TFR
- **Type Ia supernovae** (:class:`~candel.model.model_PV_SN.SNModel`):
  LOSS, Foundation
- **Pantheon+** (:class:`~candel.model.model_PV_PantheonPlus.PantheonPlusModel`):
  Pantheon+ with full covariance matrix
- **Fundamental Plane** (:class:`~candel.model.model_PV_FP.FPModel`):
  6dFGS-FP, SDSS-FP

:math:`H_0` inference
---------------------

- **Cepheid-calibrated** :math:`H_0`
  (:class:`~candel.model.model_H0_CH0.CH0Model`):
  35 Cepheid host galaxies from SH0ES
