vice.elements.yields.sneia
==========================

Type : real number or <function>

The current yield setting for type Ia supernovae (SNe Ia). 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.sneia.fractional.

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

Example Code
------------
>>> import vice
>>> vice.elements.Fe.yields.sneia = 0.0017
>>> vice.elements.O.yields.sneia = 0
>>> def z_dep_fe_yield(z):
	return 0.0017 * (z / 0.014)**0.5
>>> vice.elements.Fe.yields.sneia = z_dep_fe_yield
