Detailed Description

A class to calculate the particle density from track references. This code is used both in AliForwardMCCorrectionsTask and AliFMDMCDensity 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

Bool_t AliFMDMCTrackDensity::Calculate	(	const AliESDFMD &	esd,
		const AliMCEvent &	event,
		const TVector3 &	ip,
		AliESDFMD &	output,
		TH2D *	primary
	)

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.
