Parameters ---------- row : `~astropy.table.Row` The object containing the Cosmology information. 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 'table'. Returns ------- `~astropy.cosmology.Cosmology` subclass instance Examples -------- To see loading a `~astropy.cosmology.Cosmology` from a Row with ``from_row``, we will first make a `~astropy.table.Row` using :func:`~astropy.cosmology.Cosmology.to_format`. >>> from astropy.cosmology import Cosmology, Planck18 >>> cr = Planck18.to_format("astropy.row") >>> cr cosmology name H0 Om0 Tcmb0 Neff m_nu Ob0 km / (Mpc s) K eV str13 str8 float64 float64 float64 float64 float64[3] float64 ------------- -------- ------------ ------- ------- ------- ----------- ------- FlatLambdaCDM Planck18 67.66 0.30966 2.7255 3.046 0.0 .. 0.06 0.04897 Now this row can be used to load a new cosmological instance identical to the ``Planck18`` cosmology from which it was generated. >>> cosmo = Cosmology.from_format(cr, format="astropy.row") >>> 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) nameNr metar )columnsrdictcopydeepcopyr_tableitercolsinforupdate setdefaultpopr )rowr r rrcolmappings 8lib/python3.11/site-packages/astropy/cosmology/io/row.pyfrom_rowr sd!CK//3v;;TD tT]3844 5 5Dz""$$11 8= 1 N ! !#(- 0 0 03iiGGFO {DHH[$$?$?@@@4jjGFO li P P PP)cosmology_in_meta table_clsc:ddlm}||||}|dS)aSerialize the cosmology into a `~astropy.table.Row`.

Default is :class:`~astropy.table.QTable`. cosmology_in_meta : bool Whether to put the cosmology class in the Table metadata (if `True`) or as the first column (if `False`, default). Returns ------- `~astropy.table.Row` With columns for the cosmology parameters, and metadata in the Table's ``meta`` attribute. The cosmology class name will either be a column or in ``meta``, depending on 'cosmology_in_meta'. Examples -------- A Cosmology as a `~astropy.table.Row` will have the cosmology's name and parameters as columns. >>> from astropy.cosmology import Planck18 >>> cr = Planck18.to_format("astropy.row") >>> cr cosmology name H0 Om0 Tcmb0 Neff m_nu Ob0 km / (Mpc s) K eV str13 str8 float64 float64 float64 float64 float64[3] float64 ------------- -------- ------------ ------- ------- ------- ----------- ------- FlatLambdaCDM Planck18 67.66 0.30966 2.7255 3.046 0.0 .. 0.06 0.04897 The cosmological class and other metadata, e.g. a paper reference, are in the Table's metadata. r)to_table)clsr r)tabler#)r r r!argsr#r%s rto_rowr'Ss7R  HYIAR S S SE 8OrcTd}|dkrt|dto|dv}|S)z_Identify if object uses the `~astropy.table.Row` format.
