Comments:

This run is part of a density scan performed on 2279. The density is simply multiplied by 1.5 throughout the entire run. The results are impressive, an average bootstrap fraction of 56% and a peak of 71%. This is a great run and would be good to use the input chi's to really simulate the barrier in temperature. The temperature stays pretty high in this run, over 8 keV even with the increased density.
