vice.singlezone.enhancement
===========================

Type : real number or ``<function>``

Default : 1.0

The ratio of the outflow to ISM metallicities. Real numbers will be
taken as constant. Functions must accept time in Gyr as the only
parameter. This will apply to all elements tracked by the simulation.

.. note::

	Saving this functional attribute with VICE outputs requires the
	package dill_, an extension to ``pickle`` in the Python_ standard
	library. It is recommended that VICE user's install dill_
	>= 0.2.0.
