Constructor & Destructor Documentation

◆ TReconstProcessor() [1/2]

TReconstProcessor::TReconstProcessor ( )

Default constructor.

From telescope object and beam (tracking) object, it calculate the Ecm assuming reaction position is z = 0 for solid target.

Need variables in the steering file:

InputCollection: telescope object, inherit from art::TTelescopeData
InputTrackCollection: tracking object, inherit from art::TTrack
OutputCollection: name of output branch, inherit from art::TReactionInfo
ParticleZArray: [Z1, Z2, Z3, Z4]
ParticleAArray: [A1, A2, A3, A4]
- assuming two body reaction (NEED size 4 aray)
- [beam, target, fragment, residual]
- example: A(a,b)B reaction,
- the order is [a, A, b, B]
- this is "inverse kinematics", so we assume the detected particle is "B"

Option:

ExcitedEnergy: if you want to treat excited state transition, input the excited energy (MeV) of Z3 particles
UseCenterPosition: use center position at the detector.
- if DSSSD is not working, this flag is used.
