Update 07.19.2018 -- Run 9 data: gamma-rich purity (proper binning)

I think I've already uploaded a plot like this, but here's the gamma-rich purity as a function of 'eTtrg' binned according to our usual binning scheme.  The first plot is the "exclusive&quot

Update 07.19.2018 -- Run 9 data: charged recoil jet spectra vs. eTtrg (R = 0.2)

Below are the R = 0.2 charged recoil jet spectra for pi0 and gamma-rich triggers as a function of 'eTtrg'.  (Apologies for the wacky aspect ratios...)

Update 07.11.2018 -- Run 9 embedding: jet energy resolution, corrected response matrix

For reference, here's the jet energy resolution from the response matrix after correcting the reconstruction efficiency:

Update 07.11.2018 -- Run 9 embedding: unfolding binning check

The last time I attempted to unfold R = 0.3 charged jets, the result was pretty wiggly.  This might be due to the binning...

Update 07.10.2018 -- Run 9 embedding: match candidate qT distribution

Just for reference, here's the 'qT' distribution for all match candidates (i.e. all detector jets within acceptance with 'dR < Rjet' relative to the particle jet trying to be matched).

Update 07.10.2018 -- Run 9 embedding: our efficiency vs. h-jet efficiency

Before I had checked our efficiency compares to the corresponding efficiency from the h-jet analysis:

Update 07.09.2018 -- Run 9 embedding: response matrix before vs. after correcting reconstruction efficiency

Just to get an idea of how big the corrections are in the response matrix, I've compared the response matrix after fixing the reconstruction efficiency (which can be found in the 1st link) to the resp

Update 07.09.2018 -- Run 9 embedding: qT comparisons

After fixing the reconstruction efficiency (see link below), I was curious about how the 'qT' cuts affect the reconstruction efficiency and response matrix.  Here's a quick comparison:

Update 07.09.2018 -- Run 9 data: 1st stab at unfolding R = 0.3 charged pi0 recoil jets

Using the corrected reconstruction efficiency and response matrix (in the link below), I tried unfolding the R = 0.3 charged recoil jet (pi0 trigger) data.
