    1112 * '''''{{{gamma:}}}'''''  The constant ideal gas value of [[latex($\gamma$)]].  AstroBEAR generally assumes that the gases within the problem domain are monatomic, so [[latex($\gamma$)]] should be {{{1.6667}}} for non-isothermal problems.  For isothermal problems we use {{{1.001}}}.  Normally [[latex($\gamma_{isothermal} = 1$)]], but a [[latex($\gamma$)]] of exactly 1 is hard for our solvers to process, so we just get as close to 1 as we can.
    1213
    13  * '''''{{{gammac:}}}'''''  Used if iEOS = 1.  Can be a different real gas gamma value.
     14 * '''''{{{gammac:}}}'''''   The isentropic gamma of a real gas.  This feature is not yet implemented in AstroBEAR 2.0, so this parameter can be ignored.
    1415
    1516 * '''''{{{Xmu:}}}'''''  The mean molecular weight of the gas.  Generally specified to be 1.0 for Hydrogen.
