Detailed Description

This is the base class of all analysis classes in Rivet.

There are three virtual functions which should be implemented in base classes:

void init() is called by Rivet before a run is started. Here the analysis class should book necessary histograms. The needed projections should probably rather be constructed in the constructor.

void analyze(const Event&) is called once for each event. Here the analysis class should apply the necessary Projections and fill the histograms.

void finalize() is called after a run is finished. Here the analysis class should do whatever manipulations are necessary on the histograms. Writing the histograms to a file is, however, done by the AnalysisHandler class.

Member Function Documentation

analysisDataPath()

std::string Rivet::Analysis::analysisDataPath ( const std::string & extn, const std::string & suffix = "" )

inline

Get the path to a data file associated with this analysis.

The searched-for filename will be <ANANAME>.<extn> of suffix is empty/unspecified, or <ANANAME>-<suffix>.<extn> if a non-zero suffix is specified.

References Rivet::findAnalysisDataFile(), and name().

analyze()

virtual void Rivet::Analysis::analyze ( const Event & event )

pure virtual

Analyze one event. A concrete class should here apply the necessary projections on the event and fill the relevant histograms. An overridden function must make sure it first calls the base class function.

Implemented in Rivet::MC_JETS_BASE, Rivet::MC_KTSPLITTINGS_BASE, and Rivet::MC_PARTICLES_BASE.

apply()

template<typename PROJ = Projection>

std::enable_if_t< std::is_base_of< Projection, PROJ >::value, const PROJ & > Rivet::ProjectionApplier::apply ( const Event & evt, const Projection & proj ) const

inlineinherited

Apply the supplied projection on event evt.

Apply the supplied projection on event evt (user-facing alias).

This creates points to match the reference data's x values and errors, but with the y values and errors zeroed... assuming that there is a reference histo with the same name: if there isn't, an exception will be thrown.

Using a SingleValueProjection, proj, giving the value of an experimental observable to be used as a centrality estimator, book a CentralityProjection based on the experimentally measured pecentiles of this observable (as given by the reference data for the calHistName histogram in the calAnaName analysis. If a preloaded file with the output of a run using the calAnaName analysis contains a valid generated calHistName histogram, it will be used as an optional percentile binning. Also if this preloaded file contains a histogram with the name calHistName with an appended "_IMP" This histogram will be used to add an optional centrality percentile based on the generated impact parameter. If increasing is true, a low (high) value of proj is assumed to correspond to a more peripheral (central) event.
