Detailed Description
Smearing class describing ePHENIX momentum resolution.
The ePHENIX momentum resolution is too complicated to handle with a simple parameterisation via the Smear::Device class. Therefore we define a custom Smearer class to implement the resolution. See the email in comments at the end of the file for details of the resolution values we use.

Constructor & Destructor Documentation
◆ ~EPhenixMomentum()
|
virtual |
Destructor.
Definition at line 117 of file ePHENIXDetector.cpp.
◆ EPhenixMomentum()
| EPhenixMomentum::EPhenixMomentum | ( | bool | multipleScattering = true | ) |
Constructor.
If multipleScattering is true, apply the multiple scattering resolution in the region where it is known, 2 < eta < 4. Otherwise apply only the linear resolution term.

Member Function Documentation
◆ Clone()
|
virtual |
Duplicate this object.
Implements Smear::Smearer.
Definition at line 177 of file ePHENIXDetector.cpp.
◆ computeMultipleScattering()
|
virtual |
Return sigma(P) due to multiple scattering.
Note this means sigma(P) (GeV) not sigma(P)/P
Definition at line 216 of file ePHENIXDetector.cpp.
◆ Draw()
|
virtual |
Draw all graphs.
Definition at line 240 of file ePHENIXDetector.cpp.
◆ Graphs()
| TMultiGraph * EPhenixMomentum::Graphs | ( | ) |
Returns a pointer to the graphs.
Initialises all graphs if not yet done.
Definition at line 170 of file ePHENIXDetector.cpp.
◆ Initialise()
| void EPhenixMomentum::Initialise | ( | ) |
Initialise the object.
This is called automatically by the smearing routine, so the user needn't call it themselves before smearing.
Definition at line 124 of file ePHENIXDetector.cpp.
◆ Smear()
|
virtual |
Smears the input ParticleMC and stores the results in the ParticleMCS.
Implements Smear::Smearer.
Definition at line 185 of file ePHENIXDetector.cpp.
