Compute the L2L3Residuals calibration within the JetMET group of CMS as described by the JERC sub-group. This is done by combining the outputs from the photon+jet, dijet and Z+jet analyses.

Dependencies

An installation of ROOT is required to run the scripts.

How to run

Copy the outputs of the different analyses to a common directory with

python arrange_L2L3Res_inputs.py -v version -o work

Run the L2L3Residuals, recompiling the libraries, with

python L2L3Res.py -y all -v version

This script executes the following actions:

• make clean
• make
• Compute the L3Res doing a global fit and show the different contributions running python minitools/runAllIOVs.py -v version
• change version and year in L2Res.C and run root -l -b L2Res.C+g to compute the L2Res
• change version and year in createL2L3ResTextFile.C and run root -l -b createL2L3ResTextFile.C+g to create the text file containing the L2L3Residuals

To run the JERSF calculation, use

root -l -b -q JERSF.C+g
