0006 This code is a general purpose QA histogram maker for the calorimeters. The code is modularized to run in p+p and Au+Au via flags, so please make sure you check the flags before you run!
0007
0008 To build the code, please make sure you're sourcing a local sPHENIX build and have your LD_LIBRARY_PATH and something analogous to your MYINSTALL directory set. Refer to the day-one tutorial for setting these environment variables and building a package
0009
0010 #Building:
0011 cd src
0012 mkdir build
0013 cd build
0014 $PWD/../autogen.sh --prefix=$MYINSTALL #this should be your unique installation directory
0015 make install -j8
0016
0017 Currently there are two versions of the constructor, one for Au+Au, and one for p+p:
0018
0019 void Fun4All_CaloHistGen(const int nEvents = 10000, const std::string &fnameCalib = "/direct/sphenix+lustre01/sphnxpro/production/run3auau/physics/caloy2calib/new_newcdbtag_v005/run_00068100_00068200/DST_CALO_run3auau_new_newcdbtag_v005-00068152-00000.root", const std::string &fnameRaw = "/direct/sphenix+lustre01/sphnxpro/production/run3auau/physics/caloy2fitting/new_newcdbtag_v005/run_00068100_00068200/DST_CALOFITTING_run3auau_new_newcdbtag_v005-00068152-00000.root",const std::string &outName = "commissioning.root", const std::string &dbtag = "ProdA_2024")//Constructor for Run 25 Au+Au
0020
0021 Run 68152 appeared to have decent performance in the offline QA:
0022 https://sphenix-intra.sdcc.bnl.gov/WWW/subsystem/QAHtml/mon.cgi?runnumber=68152&runtype=physics
0023
0024
0025 And the following is the constructor to look at Run 24 p+p data:
0026 void Fun4All_CaloHistGen(const int nEvents = 0, const std::string &fnameCalib = "/direct/sphenix+lustre01/sphnxpro/production/run2pp/physics/ana468_2024p012_v001/DST_CALO/run_00052000_00052100/dst/DST_CALO_run2pp_ana468_2024p012_v001-00052032-00000.root", const std::string &fnameRaw = "/direct/sphenix+lustre01/sphnxpro/production/run2pp/physics/ana468_2024p012_v001/DST_CALOFITTING/run_00052000_00052100/dst/DST_CALOFITTING_run2pp_ana468_2024p012_v001-00052032-00000.root",const std::string &outName = "commissioning.root", const std::string &dbtag = "ProdA_2024")
0027
0028 Again watch for updates to the file system.
0029
0030 Code walkthrough:
0031 Constructor: basically tells the module what input files you're running over. Note we have one for CaloFitting and one for Calo; why we need both of them is a bit in the weeds right now, so don't worry about it. Once you start looking at physics-level things you'll use the jet dst's. Also contains the name of the output file "commissioning.root" and the cdb tag "ProdA_2024", which as far as I know hasn't changed in 2025.
0032
0033 Flags and settings:
0034 To start off, the Fun4All macro snags the run number and system type from the file name (lines 35-47).
0035 Lines 50-52 are getting the CDB ready
0036 Lines 56-62 are creating the input managers which read in the input files you provide in the constructor
0037 Line 65 IS VERY IMPORTANT YOU NEED IT IN EVERY CALORIMETER-BASED FUN4ALL MACRO YOU WRITE EVER. It applies all the calibrations we have available, which you probably want. I, personally, enjoy looking at calibrated data.
0038
0039 Line 68 and onwards really sets up the analysis module. In short, you can see the macro tells the module whether or not you're in AuAu, and then what it should store/what node names it should look for.
0040
0041 Right now, there's really no harm in turning everything on. This code used to be an nTupleMaker, so it was vitally important to have this functionality to trim the output file size, but since everything is a histogram, it really doesn't matter.
0042
0043 Most of the settings deal with pi0 reconstruction, and you should feel free to play around with these parameters:
0044 setMaxAlpha: Maximum energy asymmetry between the di-cluster pair used in reconstruction
0045 setCluster#EMin: set the minimum energy for the leading and sub leading cluster
0046 peripheralOnlyPi0: in heavy ion collisions, use only "peripheral" collisions, meaning those with low total calo energy
0047 setCaloFrac: Fraction of max calo energy allowed in analysis. We guestimated the maximum calorimeter energy and this sets the maximum fraction of that total energy. So 0.2 means you only allow events that reach 20% of the max calo energy, which should map not-so-terribly to some peripheral part of the centrality phase space
0048 setTrig: what triggers do you want? Check the header file for more options. If you don't turn it on you get everything.
