Detailed Description

copy and correct detectorhit properties

copy the position and time value from the detectorhit and then correct those values.

User definable Parameters:

AcqirisDetectors/%detectorname%/Particles/%particlename%/Corrections/{T0}
Time in ns that should be substracted from the recorded time of the detectorhit. Default is 0.

AcqirisDetectors/%detectorname%/Particles/%particlename%/Corrections/{CorrectX|CorrectY}
Position in mm that should be substracted from the x and y position of the detectorhit. Default is 0|0.

AcqirisDetectors/%detectorname%/%particlename%/Corrections/{ScaleX|ScaleY}
Factor by which the corrected position should be multiplied, to get a right sized image. Default is 1|1.

AcqirisDetectors/%detectorname%/Particles/%particlename%/Corrections/{Angle}
Angle in degree around which the corrected and scaled position should be roated. Default is 0.

particleHit_t HitCorrector::operator() ( const detectorHit_t & dethit ) const

correct the position in the detector plane

Create a particlehit. Then copy the position and the time from the dethit to the particlehit. Then correct this position, then scale the correted position and finaly rotate the corrected scaled positition around the given angle. Then substract _t0 form the time of the detectorhit
