For some reason, I'm having a lot of trouble getting the SVD algorithm to behave during unfolding.  To compare the two, I tried unfolding our R = 0.2 (pi0-triggered) charged recoil jets.  Here is the chi2 between the measured distribution and the backfolded distribution as a function of the regularization parameter:

And here are some selected unfolded and backfolded distributions:

So something seems to be off...
