Jet matching:
——————
	- AK4
	- pTgen>10 GeV
	- deltaR < R/2, R (not anti-kT: A_overlap < 75%, 50%)
	- matching criterion and parameters
	- propose to use R=0.4 with matching deltaR<Rcone/2=0.2 (loosest unambiguous match)
	- require pTgen>10 GeV, pTreco>20 GeV

Resolution
—————
	- 2 sigma fit, sigma/mu , mu (mu calibrated to 1.00)

Pile-up jet
—————
	- pile-up: Not matched within deltaR<R
	- signal: Matched within deltaR<R/2
	- gray: Matched within R/2<deltaR<R (important to know this fraction)

PU comparison
———————
	- use mu (MC truth Poisson mean) and PV,corr (=N_PU)
	- show <PV,corr> vs mu is linear at x=y (correct for any non-linearity for PV,corr)

Plots to show
——————
	- vs eta with natural segmentation
	- dpT/dmu, dpT/dPV,corr, sigma_PU from JER, 
	- JER: sigma_pT/pT = sqrt( sigma_PU^2/pT^2 + N0^2/pT^2 + S^2/pT + C^2)

Samples to use
———————
	- QCD Dijet Pythia, some tune

MET
——
	- Zmumu events
	- mean(u_parallel/pT)
	- width(u_parallel/pT)
	- width(u_perpendicular/pT)
	- width from Voigtian (or any fit with 1 sigma)
	- plot vs PU (mu), fit with sigma = sqrt(Npu*sigma_PU^2 + C^2)
