Class BarHit

java.lang.Object

org.jlab.rec.atof.hit.ATOFHit

org.jlab.rec.atof.hit.BarHit

public class BarHit
extends ATOFHit

Represents a hit in the atof bar. Extends class ATOFHit. Is further defined by the two hits upstream and downstream composing a full bar hit. z position, time and energy are defined from the up/down hits.

BarHit

public BarHit()

Method Details

getHitUp

public ATOFHit getHitUp()

isInTime

public boolean isInTime()

Computes bar time sum and check if it is around the value the hits were aligned to. For now, 40ns cut. When calibrations are final, it should be refined to reflect the resolution.

setHitUp

public void setHitUp(ATOFHit hit_up)

getHitDown

public ATOFHit getHitDown()

setHitDown

public void setHitDown(ATOFHit hit_down)

computeZ

public final void computeZ()

Computes bar hit z coordinate from up/downstream hit times.

computeTime

public final void computeTime()

Computes bar hit time from up/downstream hit times. The time is set as the time of the most energetic hit. It is corrected for propagation time.

computeEnergy

public final void computeEnergy()

Computes bar hit energy from up/downstream hits. The energy of the up/downstream hits is corrected for attenuation now that z is known. The energy of the bar hit is the sum of the energy of the up/downstream hits.

main

public static void main(String[] args)

Parameters:

args - the command line arguments
