Update 07.27.2018 -- Run 9 pp: R = 0.5 charged jets unfolding (binned according to JER)
Previously, I tried unfolding R = 0.2 charged jets using a bin size determined by the JER:
Update 07.26.2018 -- Run 9 pp: Weird SVD Behavior
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. He
Update 07.26.2018 -- Run 9 pp: Systematic Errors, Prior (R = 0.2)
After re-establishing my binning (see the link below), I tried varying the prior used in the unfolding process to get an idea of the corresponding systematic error.
Collaboration Meeting Follow-Up [07.18.2018] -- EtTrg = (9, 15) Response vs. EtTrg = (9, 20) Response
During my presentation in the JetCorr parallel session of the 2018 Collaboration Meeting at Lehigh University, a listener inquired about how different the response matrices are between using 'eTtrg =
Collaboration Meeting Follow-Up [07.18.2018] -- Variable Binning According To Jet Energy Resolution
One of the comments I received during my presentation at the 2018 Collaboration Meeting at Lehigh University (see link below) was that the extreme wiggles in the unfolded distributions on slide 10 are
Update 07.19.2018 -- Run 9 data: comparing different binning schemes for unfolded R = 0.2 charged spectra
My first attempt at unfolding R = 0.2 and R = 0.5 spectra yielded some very spiky distributions:
Update 07.19.2018 -- Run 9 data: unfolded R = 0.2 and R = 0.5 charged recoil jet spectra (pi0)
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 res
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"
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 07.19.2018 -- 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...
