Centrality Framework Wiki

Installation

    cd centrality
    mkdir build install
    cd build
    source /path-to-root/thisroot.sh
    cmake -DCMAKE_INSTALL_PREFIX=../install
    make -j
    make install -j

Examples and short description

General

main has 3 arguments:

1. input file name
2. input histo name
3. is input histo is 2D (false or true)

Example how to run it with test input file:

./main ../input/test_input.root hMreco false

or in case of 2D histogram

./main ../input/test_input.root hMEcorr true

To modify options (centrality ranges, detector type, etc) change corresponding lines in file main.cpp:

bf.SetRanges( 10,0,100 );   // number of bins, min, max value

or

bf.SetRanges( {0,10,30,60,100} );  // centrality bins borders with array

bf.IsSpectator(true);  // true if impact parameter b correlated with estimator (spectators eneggy), false - anticorrelated (multiplicity of produced particles) 
std::string outfilename = "test.root";

Minimal example on how to obtain centrality for a given event:

cd macro
root -l TestGetter.C
