Parameters ---------- map : mapping Arguments into the class -- like "name" or "meta". If 'cosmology' is None, must have field "cosmology" which can be either the string name of the cosmology class (e.g. "FlatLambdaCDM") or the class itself. move_to_meta : bool (optional, keyword-only) Whether to move keyword arguments that are not in the Cosmology class' signature to the Cosmology's metadata. This will only be applied if the Cosmology does NOT have a keyword-only argument (e.g. ``**kwargs``). Arguments moved to the metadata will be merged with existing metadata, preferring specified metadata in the case of a merge conflict (e.g. for ``Cosmology(meta={'key':10}, key=42)``, the ``Cosmology.meta`` will be ``{'key': 10}``). cosmology : str, `~astropy.cosmology.Cosmology` class, or None (optional, keyword-only) The cosmology class (or string name thereof) to use when constructing the cosmology instance. The class also provides default parameter values, filling in any non-mandatory arguments missing in 'map'. Returns ------- `~astropy.cosmology.Cosmology` subclass instance Examples -------- To see loading a `~astropy.cosmology.Cosmology` from a dictionary with ``from_mapping``, we will first make a mapping using :meth:`~astropy.cosmology.Cosmology.to_format`. >>> from astropy.cosmology import Cosmology, Planck18 >>> cm = Planck18.to_format('mapping') >>> cm {'cosmology': , 'name': 'Planck18', 'H0': , 'Om0': 0.30966, 'Tcmb0': , 'Neff': 3.046, 'm_nu': , 'Ob0': 0.04897, 'meta': ... Now this dict can be used to load a new cosmological instance identical to the ``Planck18`` cosmology from which it was generated. >>> cosmo = Cosmology.from_format(cm, format="mapping") >>> cosmo FlatLambdaCDM(name="Planck18", H0=67.66 km / (Mpc s), Om0=0.30966, Tcmb0=2.7255 K, Neff=3.046, m_nu=[0. 0. 0.06] eV, Ob0=0.04897) Specific cosmology classes can be used to parse the data. The class' default parameter values are used to fill in any information missing in the data. >>> from astropy.cosmology import FlatLambdaCDM >>> del cm["Tcmb0"] # show FlatLambdaCDM provides default >>> FlatLambdaCDM.from_format(cm) FlatLambdaCDM(name="Planck18", H0=67.66 km / (Mpc s), Om0=0.30966, Tcmb0=0.0 K, Neff=3.046, m_nu=None, Ob0=0.04897) Nrmetazthere are unused parameters .)dictpop isinstancestrr_init_signature bind_partialapply_defaults parameterskeys argumentstuplevalueskindname TypeErrorargskwargs)maprrparamsbaklastpr s >> from astropy.cosmology import Planck18 >>> Planck18.to_format('mapping') {'cosmology': , 'name': 'Planck18', 'H0': , 'Om0': 0.30966, 'Tcmb0': , 'Neff': 3.046, 'm_nu': , 'Ob0': 0.04897, 'meta': ... The dictionary type may be changed with the ``cls`` keyword argument: >>> from collections import OrderedDict >>> Planck18.to_format('mapping', cls=OrderedDict) OrderedDict([('cosmology', ), ('name', 'Planck18'), ('H0', ), ('Om0', 0.30966), ('Tcmb0', ), ('Neff', 3.046), ('m_nu', ), ('Ob0', 0.04897), ('meta', ... Sometimes it is more useful to have the name of the cosmology class, not the object itself. The keyword argument ``cosmology_as_str`` may be used: >>> Planck18.to_format('mapping', cosmology_as_str=True) {'cosmology': 'FlatLambdaCDM', ... The metadata is normally included as a nested mapping. To move the metadata into the main mapping, use the keyword argument ``move_from_meta``. This kwarg inverts ``move_to_meta`` in ``Cosmology.to_format("mapping", move_to_meta=...)`` where extra items are moved to the metadata (if the cosmology constructor does not have a variable keyword-only argument -- ``**kwargs``). >>> from astropy.cosmology import Planck18 >>> Planck18.to_format('mapping', move_from_meta=True) {'cosmology': , 'name': 'Planck18', 'Oc0': 0.2607, 'n': 0.9665, 'sigma8': 0.8102, ... z3'cls' must be a (sub)class of dict or Mapping, not rrNc"i|] \}}|dv || S))r r).0r"vs r$ zto_mapping..s4   1((( q(((r&r ) issubclassrrr __class__ __qualname__rcopydeepcopyr rupdate_init_argumentsitems)rr'r(r)rmr s r$ to_mappingr9usP cD'? + +UScSSTTT A-=U (()BUkNAfI = ( (D d###  HH  !17799    & Hr&cTd}|dkrt|dto|dv}|S)zRIdentify if object uses the mapping format.
