create_cosmology

randomfield.cosmotools.create_cosmology(*args, **kwargs)

Create a background cosmology model.

The created model will implement the astropy.cosmology.FLRW API. Input can either be a pre-defined name, or else a dictionary of parameters that can be used to initialize a new astropy.cosmology.FlatLambdaCDM. The valid names are ‘WMAP5’, ‘WMAP7’, ‘WMAP9’, ‘Planck13’.

If no arguments are specified, creates the ‘Planck13’ model.
