0001 This package is designed to subtract jets using the jet multiplicity method.
0002 The expression for the subtracted jet energy is:
0003 * pt_sub = pt_reco - rho*(N_reco - <N_signal>(pt_reco))

0005 # Building
0006 1. Build the package in the [usual way](https://wiki.bnl.gov/sPHENIX/index.php/Example_of_using_DST_nodes#Building%20a%20package):
0007
0008 * Make a build directory inside the src directory:
0009
0010 cd src
0011 mkdir build
0012 cd build
0013
0014 * Setup the sPHENIX environment and install paths:
0015
0016 source /opt/sphenix/core/bin/sphenix_setup.csh -n (source /opt/sphenix/core/bin/sphenix_setup.sh)
0017 setenv MYINSTALL ~/install (export MYINSTALL=~/install)
0018 source /opt/sphenix/core/bin/setup_local.csh $MYINSTALL (source /opt/sphenix/core/bin/setup_local.sh $MYINSTALL)
0019
0020 * Compile your code:
0021
0022 /PATH_TO_YOUR_SOURCE_DIR/autogen.csh --prefix=$MYINSTALL (/PATH_TO_YOUR_SOURCE_DIR/autogen.sh --prefix=$MYINSTALL)
0023 make -j 4
0024 make install
0025
0026 2. Run the code using the Fun4All macro:
0027
0028 * Go to the macro directory:
0029
0030 cd ../../macro
0031
0032 * Get some files to run on using CreateFileList.pl, for example to get 1000 events of pythia dijets embeded in minimum bias HIJING:
0033
0034 CreateFileList.pl -n 1000 -type 11 -embed DST_CALO_CLUSTER DST_TRUTH_JET DST_GLOBAL
0035
0036 * Test run using Fun4All. The Fun4All macro takes in input file lists for the truth jet and calo cluster DSTs. For example, you can run:
0037
0038 root -b -q 'Fun4All_JetSub.C("dst_truth_jet.list", "dst_calo_cluster.list", "dst_global.list")'
0039
0040 * This will create an output file containing all the necessary information for the histogram making.
0041 ## Options in JetMultSub
0042 There are a few options you can specify in the Fun4All macro for the JetMultSub module:
0043 * setPtRange(low, high): set the pt range of TRUTH jets you are interested in keeping in your tree
0044 * setEtaRange(low, high): set the eta range of TRUTH jets you are interested in keeping in your tree
0045 * add_reco_input(string): add a reco jet input to the tree. The string should be the name of the reco jet node in the DST. Default is "AntiKt_Tower_r04"
0046 * add_kt_input(string): add a kt jet input to the tree. The string should be the name of the kt jet node in the DST. Default is "Kt_Tower_r04"
0047 * set_output_name(string): set the name of outout DST. default is "AntiKt_Tower_r04_sub"
