Detailed Description

A class to calculate the particle eloss from track references. This code is used both in AliForwardMCCorrectionsTask and AliFMDMCEloss calculator.

Input:

• AliESDFMD object - from reconstruction
• Kinematics
• Track-References

Output:

• AliESDFMD object - content is # of track references/strip

Corrections used:

• None

Histograms:

• Incident angle vs number of track references
• Incident angle vs number of strips/cluster

Member Function Documentation

void AliFMDMCTrackELoss::BeginTrackRefs ( )

protectedvirtual

Called at before loop over track references

Reimplemented from AliBaseMCTrackDensity.

Definition at line 260 of file AliFMDMCTrackELoss.cxx.

Bool_t AliFMDMCTrackELoss::Calculate	(	const AliESDFMD &	esd,
		const AliMCEvent &	event,
		const TVector3 &	ip,
		Double_t	cent
	)

Loops over all the particles in the passed event. If primary is not null, then that histogram is filled with the primary particle information - irrespective of whether the particle actually hits the FMD or not. For each track (primary or secondary, unless only primary information is requested - see SetUseOnlyPrimary) loop over all track references to that particle and check if they come from the FMD. In that case, figure out which strip(s) to assign the track to, and fill the hits structure.

Parameters

esd	FMD ESD structure
event	MC event
ip	IP coordinates
cent	Event centrality

Returns

true
