bool DTrackingResolution::Efficiency ( int  geanttype, const TVector3 &  mom  )

inherited

Return a boolean saying whether this event would be reconstructed or not. The value returned will vary in that if mom points to an area of the detector with 80% efficienct, then this will return "true" 80% of the time and "false" 20% of the time.

Geometric acceptance is also included so values of mom pointing away from the detector will always returen "false".

This works by calling the GetEfficiency method and then picking a random number between 0 and 1. If the random number is less than or equal to the efficiency value, then true is returned . Otherwise, false is returned.

double DTrackingResolutionGEANT::GetEfficiency ( int  geanttype, const TVector3 &  mom  )

virtual

Return the reconstruction efficiency for a charged particle based on results from GEANT-based Monte Carlo studies.

Implements DTrackingResolution.

void DTrackingResolutionGEANT::GetResolution ( int  geanttype, const TVector3 &  mom, double &  pt_res, double &  theta_res, double &  phi_res  )

virtual

Return the momentum and angular resolutions for a charged particle based on results from GEANT-based Monte Carlo studies.

Implements DTrackingResolution.

Definition at line 95 of file DTrackingResolutionGEANT.cc.

bool DTrackingResolution::Smear ( int  geanttype, TVector3 &  mom  )

inherited

Smear the momentum vector of a charged particle based on reolutions obtained from the GetResolution method.

The value of geanttype should specify the particle type using the GEANT particle ids.

The units of mom should be GeV/c
