# CHOLLA_PM: Power Spectrum No half update

**Column 1:** ENZO

**Column 2:** Phase diagram for All Gas ( top ) and Neutral Hydrogen ( bottom ). Temperature is internally 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.

**Column 5:** Phase diagram showing the temperature computed from the Total Internal Energy for ALL the gas.

**Column 6:** Phase diagram showing the temperature computed from the Advected Internal Energy for ALL the gas.

Here is a comparison of the phase diagram using for all the reconstruction methods without the half-step update.

**Row 1:** PCM

**Row 2:** PLMP

**Row 3:** PLMC

**Row 4:** PPMC

For some reason PPMP crashes immediately.
