Below are the 1st stabs at unfolding the R = 0.2 and R = 0.5 pi0-triggered charged recoil jet spectra using the new (and improved) response matrices.  Here are the R = 0.2 and R = 0.5 charged response matrices:

I apologize for the odd 'eTtrg' range; however, the differences between the 'eTtrg = 9 - 20' GeV and 'eTtrg = 9 - 15' GeV should be small to nonexistent.  Though I still need to check that... First are the performance plots for the different binning schemes and jet radii.

R = 0.2, 'pTbin = 1' GeV:

R = 0.2, 'pTbin = 2' GeV:

R = 0.2, variable binning:

R = 0.2, bigger variable binning:

R = 0.5, 'pTbin = 1' GeV:

R = 0.5, 'pTbin = 2' GeV:

R = 0.5, variable binning:

R = 0.5, bigger variable binning:

I'm not sure what yet, but something's going on with the SVD algorithm.  Either way, here are the backfolding results for various binning schemes and regularization parameters.

R = 0.2:

R = 0.5:

And here are the corresponding unfolded distributions (for various different regularization parameters).
