The Module parameter list class.
Base class for filters on a generic object type.
Definition: Filter.dcl.h:29
Filter for relations based on the polar angle difference and the time difference of the hits.
double m_ThetaCutDeltaL2
Filter relations in theta between hit states where the layer difference is +-2.
double m_ThetaCutDeltaL1
Filter relations in theta between hit states where the layer difference is +-1.
double m_DeltaTU
Cut on difference in u-side cluster time of the two hits.
TrackFindingCDC::Weight operator()(const std::pair< const VXDHoughState *, const VXDHoughState * > &relation) override
Return the weight based on azimuthal-angle separation and the time difference of the hits on both sid...
double m_ThetaCutDeltaL0
Cut on relations in theta for overlay region on same layer but different ladder.
double m_DeltaTV
Cut on difference in v-side cluster time of the two hits.
void exposeParameters(ModuleParamList *moduleParamList, const std::string &prefix) override
Expose the parameters.
Abstract base class for different kinds of events.
