Detailed Description

template<typename T = Histo1DPtr, typename MDist = MergeDistance>
class Rivet::CentralityBinner< T, MDist >

CentralityBinner contains a series of AnalysisObject of the same quantity each in a different percentiles of another quantity. For example, a CentralityBinner may e.g. contain histograms of the cross section differential in \( p_T \) in different centrality regions for heavy ion collisions based on forward energy flow.

Constructor & Destructor Documentation

CentralityBinner()

template<typename T = Histo1DPtr, typename MDist = MergeDistance>

Rivet::CentralityBinner< T, MDist >::CentralityBinner ( int  maxbins = 200, double  wlim = 0.02  )

inline

Create a new empty CentralityBinner. maxbins is the maximum number of bins used by the binner. Default is 1000, which is typically enough. wlim is the mximum allowed error allowed for the centrality limits before a warning is emitted.

Member Function Documentation

add()

template<typename T = Histo1DPtr, typename MDist = MergeDistance>

void Rivet::CentralityBinner< T, MDist >::add ( T  t, double  cmin, double  cmax, double  cestmin = -1.0, double  cestmax = -1.0  )

inline

Add an AnalysisObject in the region between cmin and cmax to this set of CentralityBinners. The range represent percentiles and must be between 0 and 100. No overlaping bins are allowed. Note that (cmin=0, cmax=5), means the five percent MOST central events although the internal notation is reversed for convenience. Optionally supply corresponding limits cestmin and cestmax of the centrality extimator.

const PROJ & Rivet::ProjectionApplier::declare ( const std::string &  name, const PROJ &  proj  ) const

inlineprotectedinherited

Register a contained projection (user-facing, arg-reordered version)

Todo:

edges()

template<typename T = Histo1DPtr, typename MDist = MergeDistance>

map< double, double > Rivet::CentralityBinner< T, MDist >::edges ( ) const

inline

Return a map bin edges of the centrality extimator indexed by the corresponing percentile.

estimator()

template<typename T = Histo1DPtr, typename MDist = MergeDistance>

double Rivet::CentralityBinner< T, MDist >::estimator ( ) const

inline

Return the value of the centrality estimator set in the latest call to select().

finalize()

template<typename T , typename MDist >

void Rivet::CentralityBinner< T, MDist >::finalize

(

)

At the end of the run, calculate the percentiles and fill the AnalysisObjectss provided with the add() function. This is typically called from the finalize method in an Analysis, but can also be called earlier in which case the the select functions can be continued to run as before with the edges between the centrality regions now fixed.

Return one of the AnalysisObjects in the CentralityBinner for the given event.

This should be the weight that will be used to fill the AnalysisObject. If the centrality estimate is less than zero, the _devnull object will be returned.
