IonBase#

class fiasco.base.IonBase(ion_name, hdf5_dbase_root=None, **kwargs)[source]#

Base class for accessing data attached to a particular ion.

Note

This is not meant to be instantiated directly by the user and primarily serves as a base class for Ion.

Parameters:

ion_name (str) – Name of ion, e.g. for Fe V, ‘Fe 5’, ‘iron 5’, ‘Fe 4+’
hdf5_dbase_root (str, optional) – Path to the root of the CHIANTI HDF5 database. If not provided, the default path is used.
kwargs – Further keyword arguments are passed to fiasco.util.check_database.
