set_current

astropy.cosmology.core.set_current(cosmo)

Set the current cosmology.

Call this with an empty string (‘’) to get a list of the strings that map to available pre-defined cosmologies.

Warning

set_current is the only way to change the current cosmology at runtime! The current cosmology can also be read from an option in the astropy configuration file when astropy.cosmology is first imported. However, any subsequent changes to the cosmology configuration option using ConfigurationItem.set at run-time will not update the current cosmology.

Parameters :

cosmo : str or Cosmology instance

The cosmology to use.
