Following up from earlier today:

I wanted to check what happens when I unfold with a response matrix created for each bin of eTtrg, e.g. eTtrg = (9, 11) GeV.  Using the same unfolding parameters as I used in the link above, I unfolded each bin of eTtrg using the corresponding response matrix.  It doesn't seem to make a big difference...

eTtrg = 9 - 11 GeV:

eTtrg = 11 - 15 GeV:

eTtrg = 15 - 20 GeV:

The discrepancies between the unfolded and Pythia, by eye, are still present (and in the same direction) as previously.
