    eintSwitch [REAL] [0.0]
        Valid Values: Unconstrained
        a rarely used switch which ensures that internal energy calculations
        maintain sufficient precision. Important only if energyTotal is
        dominated by energyKinetic. If (energyInternal <
        eintSwitch*energyKinetic) then some routines (Eos/Helmholtz,
        Hydro/hy_updateSoln) will NOT calculate energyInternal by subtraction,
        but rather through direct calculation.
    eos_entrEleScaleChoice [INTEGER] [6]
        Valid Values: 1 to 8
        selects a scale variant for representing electron entropy. See code in
        eos_idealGamma for the meaning of the various choices. The choice that
        corresponds most closely to the Sackur-Tetrode equation in physical
        units should be 3, closely followed by 2.

        is dominated by bulk kinetic energy. A value of -1 means to use the

        return in the EOS_TEMP part of eosData, when Eos is called in a mode for
        which EOS_TEMP is an output and different component temperatures can be
        returned. 1 for ion temperature EOS_TEMPION; 2 for electron temperature
        EOS_TEMPELE; 3 for radiation temperature EOS_TEMPRAD; 0 for the
        temperature that would result in the same specific internal energy as
        given if all components where equilibrated at the same temperature,
        which may be expensive to compute; -10 for undefined, i.e., we do not
        care what is returned. Currently only implemented for Multitype Eos.
