Column 1: ENZO

Next three columns: CHOLLA computing pressure from total internal energy or advacted internal enegy using $\eta_1=0.001$ and $\eta_2 =0.1$ ( same as Bryan 2014 )

Column 2: Phase diagram for All Gas ( top ) and Neutral Hydrogen ( bottom ). Temperature is internaly computed by Grackle on run time.

Column 3: Phase diagram for the fraction of the gas that uses the Total Internal Energy to compute pressure.

Column 4: Phase diagram for the fraction of the gas that uses the Adavected Internal Energy to compute pressure.

Last three columns: CHOLLA computing pressure from total internal energy or advacted internal enegy using $\eta_1=0.02$ and $\eta_2 =0.1$

Column 5: Phase diagram for All Gas ( top ) and Neutral Hydrogen ( bottom ). Temperature is internaly computed by Grackle on run time.

Column 6: Phase diagram for the fraction of the gas that uses the Total Internal Energy to compute pressure.

Column 7: Phase diagram for the fraction of the gas that uses the Adavected Internal Energy to compute pressure.
