The only changes appear to be in the code that deals with the MC response of the detector.  The clustering algorithm hasn't change and the nonlinear correction is the very thing we are discussing:  it worked, then it didn't.

We will retune once we get the green light that all low level changes have been made and propagated into the master for use.
