The Module parameter list class.
Base class for filters on a generic object type.
Definition: Filter.dcl.h:29
AObject Object
Type of the object to be analysed.
Definition: Filter.dcl.h:33
Class that allows the calculation of simple variables to estimate the quality of a triplet of hits.
Filter for two hits plus a virtual IP.
TrackFindingCDC::Weight operator()(const BasePathFilter::Object &pair) override
Return the weight based on the ThreeHitVariables.
ThreeHitVariables m_threeHitVariables
Construct empty ThreeHitVariables instance.
void beginRun() override
set BField value for estimator
double m_cosRZCut
cut for cosine in RZ between the two vectors (oHit - cHit) and (cHit - iHit)
double m_circleIPDistanceCut
cut on the difference between circle radius and circle center position in the x-y plane to check if t...
void exposeParameters(ModuleParamList *moduleParamList, const std::string &prefix) override
Expose the parameters.
Abstract base class for different kinds of events.
