Detailed Description

The detector structure. A detector posseses a collection of Smearer objects, each smearing some variable(s). It contains a detector-level smearing function which applies smearing of all its devices to the provided ParticleMCS. The detector can also generate event-wise smeared kinematics if provided with smeared particles from that event.

Here is the caller graph for this function:

void Smear::Detector::FillEventKinematics ( Event * event )

Calculate event-wise smeared kinematics for an event which has already had its particles smeared and stored in eventS. Newly calculated values are stored in eventS.

This uses the null momentum (m->0) approximation for the scattered lepton, so you should be careful about using low energy muons, and if for some strange reason you want to use taus, this probably won't work too well.

Also, the smeared lepton momentum (as opposed to energy) is used in the assumption that its smearing is less severe.

void Smear::Detector::SetEventKinematicsCalculator ( TString s )

Set the method for calculating event kinematics if FillEventKinematics is used. String must contain "NM" for null momentum approximation (using scattered lepton), "JB" for Jacquet Blondel method, or "DA" for double angle method. Strings not containing one of these turns the method off.

Remarks: Simply accessing the EventKinematicsComputer may be more straightforward

ParticleMCS * Smear::Detector::Smear ( const erhic::VirtualParticle & prt ) const

Detector level particle smearing. Returns a pointer to a new smeared particle, which is a version of the input Particle that has been smeared by all the detector's devices. Smearing is only be applied to final-state particles. If the input particle is unstable or an initial- or intermediate- state particle, returns a null ParticleS pointer.
