Number fractions and mass fractions for the Z elements through Ni are given for Cunha 2006 below.  This set is based upon the AGS05 set with Ne enhanced by nearly a factor of 2.  Heavier elements are included in the computation of the fractions, but are a very small part of the 6th decimal place.  Li, Be, B are not included due to their small abundances too.
