Detailed Description

Author: Christian Holm Christensen cholm.nosp@m.@nbi.nosp@m..dk Task to convert AOD MC tables into HepMC event structure

This assumes that the following tables are available on the input:

o2::aod::McCollisions
o2::aod::McParticles
o2::aod::HepMCXSections
o2::aod::HepMCPdfInfos
o2::aod::HepMCHeavyIons

The application o2-sim-mcevent-to-aod publishes these tables.

Ideally, this application should work with the case where only

This is selected by the option --hepmc-no-aux

The thing to remember here, is that each task process is expected to do a complete job. That is, a process cannot assume that another process has been called before-hand or will be called later, for the same event in the same order.

That is, each process will get all events of a time-frame and then the next process will get all events of the time-frame.

Processed do not process events piece-meal, but rather in whole.

AodToHepmc::configs

◆ doPlain

decltype(o2::framework::ProcessConfigurable{&AodToHepmc::processPlain, "hepmc-no-aux", false, "Do not process auxiliary " "information"}) AodToHepmc::doPlain

Initial value:

= o2::framework::ProcessConfigurable{&AodToHepmc::processPlain,
                                                 "hepmc-no-aux", false,
                                                 "Do not process auxiliary "
                                                 "information"}

Make a process option.

Instead of using the provided preprocessor macro, we instantise the template directly here. This is so that we can specify the command line argument (--hepmc-no-aux) rather than to rely on an auto-generated name (would be --processPlain).

◆ dump

o2::framework::Configurable<std::string> AodToHepmc::dump

Initial value:

{"hepmc-dump", "",

◆ onlyGen

o2::framework::Configurable<bool> AodToHepmc::onlyGen

Initial value:

{"hepmc-only-generated", false,

"Only export generated"}

Option for only storing particles from the event generator. Note, if a particle is stored down, then its mothers will also be stored.

Definition at line 60 of file o2aod_mc_to_hepmc.cxx.

◆ precision

o2::framework::Configurable<int> AodToHepmc::precision

Initial value:

{"hepmc-precision", 8,

o2::framework::Configurable<bool> AodToHepmc::recenter

Initial value:

{"hepmc-recenter", false,

"Recenter the events at (0,0,0,0)"}

Recenter event at IP=(0,0,0,0).

"Export as tree"}

Use HepMC's tree parsing for building event structure
