Mini-framework to study possible parameterizations of the QCD-multijet background

Usage

First, compile the code with scram b.

The central executable is called FitBackgroundModel and the available options are obtained with FitBackgroundModel -h. An example call would look like this:

FitBackgroundModel -b bukin

Use the flags -l to see the parameters of the chosen model and -m to modify the parameter settings from the command line.

Memory analysis with valgrind

valgrind --tool=memcheck --track-origins=yes \
 --suppressions=$CMSSW_RELEASE_BASE/src/Utilities/ReleaseScripts/data/cms-valgrind-memcheck.supp \
 --suppressions=$ROOTSYS/etc/valgrind-root.supp \
 FitBackgroundModel -b bukin

NB: Compile with the following flags in Analysis/BackgroundModel/BuildFile.xml and Analysis/BackgroundModel/bin/BuildFile.xml:

<flags CXXFLAGS="-g -O0" />

This is also useful for using gdb.
