Parameters ---------- cosmo : |Cosmology|-like, positional-only |Cosmology| to parse. format : bool or None or str, positional-only Whether to allow, before equivalence is checked, the object to be converted to a |Cosmology|. This allows, e.g. a |Table| to be equivalent to a |Cosmology|. `False` (default) will not allow conversion. `True` or `None` will, and will use the auto-identification to try to infer the correct format. A `str` is assumed to be the correct format to use when converting.

Parameters ---------- cosmo1, cosmo2 : |Cosmology|-like The objects to compare. Must be convertible to |Cosmology|, as specified by ``format``. format : bool or None or str or tuple thereof, optional keyword-only Whether to allow the arguments to be converted to a |Cosmology|. This allows, e.g. a |Table| to be given instead a |Cosmology|. `False` (default) will not allow conversion. `True` or `None` will, and will use the auto-identification to try to infer the correct format. A `str` is assumed to be the correct format to use when converting. Note ``format`` is broadcast as an object array to match the shape of ``cosmos`` so ``format`` cannot determine the output shape. allow_equivalent : bool, optional keyword-only Whether to allow cosmologies to be equal even if not of the same class. For example, an instance of |LambdaCDM| might have :math:`\Omega_0=1` and :math:`\Omega_k=0` and therefore be flat, like |FlatLambdaCDM|. Examples -------- Assuming the following imports >>> import astropy.units as u >>> from astropy.cosmology import FlatLambdaCDM Two identical cosmologies are equal. >>> cosmo1 = FlatLambdaCDM(70 * (u.km/u.s/u.Mpc), 0.3) >>> cosmo2 = FlatLambdaCDM(70 * (u.km/u.s/u.Mpc), 0.3) >>> cosmology_equal(cosmo1, cosmo2) True And cosmologies with different parameters are not. >>> cosmo3 = FlatLambdaCDM(70 * (u.km/u.s/u.Mpc), 0.4) >>> cosmology_equal(cosmo1, cosmo3) False Two cosmologies may be equivalent even if not of the same class. In these examples the |LambdaCDM| has :attr:`~astropy.cosmology.LambdaCDM.Ode0` set to the same value calculated in |FlatLambdaCDM|. >>> from astropy.cosmology import LambdaCDM >>> cosmo3 = LambdaCDM(70 * (u.km/u.s/u.Mpc), 0.3, 0.7) >>> cosmology_equal(cosmo1, cosmo3) False >>> cosmology_equal(cosmo1, cosmo3, allow_equivalent=True) True While in this example, the cosmologies are not equivalent. >>> cosmo4 = FlatLambdaCDM(70 * (u.km/u.s/u.Mpc), 0.3, Tcmb0=3 * u.K) >>> cosmology_equal(cosmo3, cosmo4, allow_equivalent=True) False Also, using the keyword argument, the notion of equality is extended to any Python object that can be converted to a |Cosmology|. >>> mapping = cosmo2.to_format("mapping") >>> cosmology_equal(cosmo1, mapping, format=True) True Either (or both) arguments can be |Cosmology|-like. >>> cosmology_equal(mapping, cosmo2, format=True) True The list of valid formats, e.g. the |Table| in this example, may be checked with ``Cosmology.from_format.list_formats()``. As can be seen in the list of formats, not all formats can be auto-identified by ``Cosmology.from_format.registry``. Objects of these kinds can still be checked for equality, but the correct format string must be used. >>> yml = cosmo2.to_format("yaml") >>> cosmology_equal(cosmo1, yml, format=(None, "yaml")) True This also works with an array of ``format`` matching the number of cosmologies. >>> cosmology_equal(mapping, yml, format=[True, "yaml"]) True F) __equiv__NotImplemented)rlrmrkeqs rcosmology_equalrrsfD  3 v   f % %   !!&))BN**UU Irc,t||| }|S)aTReturn element-wise cosmology non-equality check. .. note:: Cosmologies are currently scalar in their parameters. Parameters ---------- cosmo1, cosmo2 : |Cosmology|-like The objects to compare. Must be convertible to |Cosmology|, as specified by ``format``. out : ndarray, None, optional A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned. format : bool or None or str or tuple thereof, optional keyword-only Whether to allow the arguments to be converted to a |Cosmology|. This allows, e.g. a |Table| to be given instead a Cosmology. `False` (default) will not allow conversion. `True` or `None` will, and will use the auto-identification to try to infer the correct format. A `str` is assumed to be the correct format to use when converting. ``format`` is broadcast to match the shape of the cosmology arguments. Note that the cosmology arguments are not broadcast against ``format``, so it cannot determine the output shape. allow_equivalent : bool, optional keyword-only Whether to allow cosmologies to be equal even if not of the same class.
