Class for accessing objects in the database.
Definition: DBObjPtr.h:21
The module implements charged particle identification using ECL-related observables.
virtual ~ECLChargedPIDModule()
Destructor, use to clean up anything you created in the constructor.
virtual void initialize() override
Use this to initialize resources or memory your module needs.
DBObjPtr< ECLChargedPidPDFs > m_pdfs
Interface to get the DB payload for ECL charged PID PDFs.
virtual void event() override
Called once for each event.
virtual void endRun() override
Called once when a run ends.
virtual void terminate() override
Clean up anything you created in initialize().
double getPdfVal(const double &x, const TF1 *pdf)
Extract the PDF value for a given variable from the TF1 object.
static constexpr double c_sqrt2
Defintion of sqrt(2)
ECLChargedPIDModule()
Constructor, for setting module description and parameters.
int linIndex(int i, int j, int m)
Get the index corresponding to element i,j in a linearised n*m array.
StoreObjPtr< EventMetaData > m_eventMetaData
The event information.
static constexpr double c_dummyLogL
Dummy value of Log Likelihood for a particle hypothesis.
void transfoGaussDecorr(const unsigned int pdg, const int charge, const double &p, const double &theta, std::vector< double > &variables)
Transform input variables according to:
void checkPdfsDB()
Check the PDFs payload for consistency everytime they change in the database.
virtual void beginRun() override
Called once before a new run begins.
std::unordered_map< ECLChargedPidPDFs::InputVar, double > m_variables
Map to contain ECL shower observables.
StoreArray< Track > m_tracks
Array of Track objects.
bool m_applyClusterTimingSel
Apply cluster timing selection.
StoreArray< ECLPidLikelihood > m_eclPidLikelihoods
Array of ECLPidLikelihood objects.
@ c_DeltaL
DeltaL (track depth)
@ c_E
Energy of maxE shower.
@ c_LAT
Lateral shower shape.
Base class for Modules.
Definition: Module.h:72
Accessor to arrays stored in the data store.
Definition: StoreArray.h:113
Type-safe access to single objects in the data store.
Definition: StoreObjPtr.h:96
Abstract base class for different kinds of events.
