vice.elements.yields.ccsne
==========================

Type : real number or <function>

The current yield setting for core collapse supernovae (CCSNe). If
this is a real number, it will be interpreted as a constant,
metallicity-independent yield. If it is a function, it must accept
the metallicity by mass :math:`Z` as the only parameter.

These values can be calculated by calling vice.yields.ccsne.fractional.

.. note:: Modifying yield settings here is equivalent to modifying
	vice.yields.ccsne.settings.

Example Code
------------
>>> import vice
>>> vice.elements.Fe.yields.ccsne = 0.0012
>>> vice.elements.O.yields.ccsne = 0.015
>>> def z_dep_o_yield(z):
	return 0.015 * (z / 0.014)**0.5
>>> vice.elements.O.yields.ccsne = z_dep_o_yield
