class astropy.cosmology.FlatCosmologyMixin[source]¶

Bases: object

Mixin class for flat cosmologies. Do NOT instantiate directly. Note that all instances of FlatCosmologyMixin are flat, but not all flat cosmologies are instances of FlatCosmologyMixin. As example, LambdaCDM may be flat (for the a specific set of parameter values), but FlatLambdaCDM will be flat.
