[FLASH-USERS] confusion regarding abar and zbar

[Jonathan Slavin]

​Hi Dean,

But if you look in section 15.4.1 it states something different:
"​This EOS can include contributions from radiation, partially or
completely ionized nuclei, and electrons. The desired (constant) ionization
level $ {\bar Z}$ of the nuclei should be specified with the
eos_singleSpeciesZ runtime parameter."
