Cold runs, recentered

Here are the power law cold runs, done with the updated recentering algorithm.   The initial conditions for these runs is $\rho \propto x^a$ with $a=-0.5, -0.7, -0.8, -0.3, +0.5$  They all have 10k particles.

Also, here is the run with $a=-0.2$, and 80k particles.

The cold runs with slope <-0.5 appear to exhibit the same flattening in the center as the warm runs.  Qualitatively, the warm and cold appear indistinguishable.  However, runs with initial slope >-0.5 do not appear to retain their original scaling, and they do not go to the attractor behavior, even when they are cold.   The run with initial slope >0 appears to do something like the attractor behavior, oddly enough.
